Description

  The present invention relates to a production management technology for a product, and more particularly to a technology for creating a checklist and managing work results.

  2. Description of the Related Art Conventionally, for example, in a production line of a machine assembly factory, a work management sheet that serves as both a work instruction called a check sheet and a work performance record flows along the work target member.

  The worker looks at the check sheet, confirms the work contents in his process, and records the work result. Specifically, the operator confirms that the necessary work has been performed without fail while performing the assembly work, and the serial number of the parts used in the product, and the in-process inspection result included in the assembly work. Etc. on the check sheet with your signature.

  The person in charge of quality assurance can confirm that necessary work has been performed by an appropriate worker by referring to the check sheet later. In addition, if a defect occurs in the product after shipment, etc., the quality assurance staff will check the numerical value of the inspection result related to the defect based on the contents recorded on the check sheet, To track production lots of parts.

  However, since the check sheet that has been used conventionally is a paper check sheet, it takes a lot of time and effort to confirm the work contents later. For example, if a problem occurs in a certain product, it is possible to check the work results of that product and the details of the parts used in that product from the huge number of paper files stored at the manufacturing site. This is because the quality assurance staff needed to find the check sheet.

  Also, in the case of a paper check sheet, if the product is not manufactured at one factory, but the product is manufactured in parts at multiple locations, it is difficult to collectively manage the manufacturing history There are many. In particular, in recent years, there have been cases where manufacturing bases are located in other countries, for example, core parts such as engines are manufactured in Japan and peripheral parts are manufactured in factories in emerging countries close to the market. As the distribution of the process proceeds, it is becoming more difficult to manage the manufacturing history of the paper check sheet.

  Against this backdrop, with the progress of recent information communication technology (Information Communication Technology), manufacturing history can be managed in real time regardless of the location of the manufacturing line, and the search and analysis of results The introduction of electronic check sheets that can be easily performed has been studied.

  For example, a work instruction system is provided with a database in which work instruction data such as work procedure information including design information, equipment, jigs, etc. of each product to be manufactured is stored in advance and an information terminal installed at a work site. Work instruction data corresponding to the product is distributed to the information terminal used by the worker. A technique has been proposed in which work progress information is collected via an information terminal and work instructions according to the progress are presented in a timely manner (see, for example, Patent Document 1).

JP 09-262745 A

  Here, in this prior art, a check sheet (work instruction data) in which work procedures and the like corresponding to one-to-one are described in advance for the product type name to be manufactured (name indicating the product model specification) is prepared. Must be stored in the database. That is, as the types of products increase, the person in charge needs to prepare check sheets for the increased product model specifications in a timely manner in time for manufacturing.

  However, in recent years, production lines that have been manufactured in a variety of small quantities have a total number of model specifications of products manufactured in one line, which may exceed 1,000 types. It may be difficult in practice to continue to maintain.

  In addition, when using a design method such as modular design or front loading, a check sheet for each product is created by linking the system that manages the design information with the production design process to deal with requirements in the manufacturing process. Although it is possible to develop a system that creates and maintains a system in a timely manner, time and a large investment are required.

  Accordingly, an object of the present invention is to provide a technology that can easily create a check sheet corresponding to the model specifications of individual products to be manufactured in a manufacturing line characterized by high-mix low-volume production.

  The checklist creation apparatus according to the first aspect of the present invention is model specification data that defines specifications of a plurality of products belonging to a predetermined product group, and includes a plurality of functions indicating features of the functions of the plurality of products. A feature item, a feature option item indicating one or more feature options belonging to each of the plurality of functional feature items, and a feature option indicated by the feature option item are selected by each of the plurality of products. A first storage unit that stores model specification data including a model specification item indicating whether or not there are, a plurality of check items respectively indicating check processing performed on any product belonging to the product group, Each check process indicated by a plurality of check items is selected as the feature option indicated by each feature option item. A second storage unit that stores check item data including an execution selection item indicating whether or not to perform the operation, and a first product belonging to the product group based on the model specification data and the check item data A list creation unit that creates a check item list in which the check items indicating the check processing performed are arranged, and the list creation unit includes the model specification of the model specification data of the first product The implementation selection corresponding to the first check item of the check item data indicates that the option of the feature indicated by the first feature option item belonging to any of the plurality of functional feature items is selected. When the item indicates that the check process is performed on the feature option indicated by the first feature option item, It is intended to include the check items in the check items list.

  The checklist creation method according to the second aspect of the present invention is model specification data that defines specifications of a plurality of products belonging to a predetermined product group, and a plurality of functions indicating features of the functions of the plurality of products. A feature item, a feature option item indicating one or more feature options belonging to each of the plurality of functional feature items, and a feature option indicated by the feature option item are selected by each of the plurality of products. A first storage unit that stores model specification data including a model specification item indicating whether or not there are, a plurality of check items respectively indicating check processing performed on any product belonging to the product group, Each check process indicated by a plurality of check items is selected as the feature option indicated by each feature option item. A check list creation method used in a check list creation apparatus comprising: a second storage unit that stores check item data including an execution selection item indicating whether or not to perform the operation, wherein the model specification data and A list creation step for creating a check item list in which the check items indicating the check processing performed on the first product belonging to the product group are arranged based on the check item data; The model specification item of the model specification data of the first product indicates that the option of the feature indicated by the first feature option item belonging to any of the plurality of function feature items is selected, The execution selection item corresponding to the first check item of the check item data is determined by the first feature option item. If the relative selection of the feature to be indicating that the checking process is performed, in which the first check item is included in the check item list.

  According to these configurations, model specification data that associates a product with features of the function of the product, a check item that indicates a check process, and a check item that associates a choice of a feature with which the check process is performed If each data is created, a check item list for each product can be created. Here, the feature of the function widely indicates the feature of the product, and may include not only the function of the product but also the place or area where the product is used.

  When creating and storing check item lists from scratch for each product, create various types of check item lists, taking into account the combination of the features of each product and the check items. In many cases, a large amount of labor is required for the maintenance of the check item list. However, a number of data structures with a simple correspondence, such as model specification data and check item data with the above configuration, are stored, and if necessary, information is aggregated to create a check item list By doing so, it becomes possible to reduce a load compared with the case where the check item list is maintained for each product. By using this check item list, it is possible to operate individual check sheets for each product corresponding to high-mix low-volume production without introducing a large-scale mechanism linked with the design management system.

  The work performance management system according to a third aspect of the present invention is the work terminal installed in the work area to which the production processes of the plurality of products are assigned, and is connected to the work terminal in a communicable manner. The work terminal management system has a check list creation device, wherein the work terminal includes a display unit and a product identifier that identifies a target product that is a target of work performed in the work area, in the check list creation device. A first acquisition unit that transmits and receives the check item list of the target product specified by the product identifier from the check list creation device; and the check item included in the check item list on the display unit A second acquisition unit that displays the execution result of the check process indicated by the check item input by the user; A transmission unit that transmits the execution result acquired by the unit to the check list creation device, the check list creation device receives the product identifier from the work terminal, and is included in the check item list A communication unit that receives an execution result of the check process indicated by the check item from the work terminal, and the list creation unit uses the target product specified by the product identifier as the first product as the first product. A check item list is created, and the communication unit transmits the created check item list to the work terminal.

  According to this configuration, the worker who is the user can easily and clearly grasp the check process to be performed at the work place from the displayed check items, and also the electronic result of the check process, that is, the work Achievements can be entered. Since the work results are collected in the check list creation device, the person in charge of production can grasp the work progress in real time by referring to the collected work results regardless of the production base. In addition, if there is a problem with the product after shipment, the quality assurance staff can immediately grasp the manufacturing history or measurement values by referring to the work results collected in the checklist creation device. It becomes.

  The work performance management system described above may further include a storage device configured to be communicable with the terminal device and storing related documents related to the check items. The check item data stored in the second storage unit may further include a document identifier that identifies the related document associated with each of the plurality of check items. The storage device may store the related document in association with the document identifier. The work terminal includes a third acquisition unit that acquires the document identifier selected by the user, and the related document stored in the storage device in association with the document identifier acquired by the third acquisition unit. A display control unit that receives the information from the storage device and displays it on the display unit.

  According to this configuration, the user can immediately refer to related documents related to the check items, such as design drawings and procedure manuals, by simply selecting the document identifier. That is, the user can easily check the necessary work procedure manual and test procedure manual without leaving the production line, so that the work quality can be improved.

  Moreover, in the above-described work performance management system, the check item data stored in the second storage unit further includes the check process indicated by the check item associated with each of the plurality of check items. Order information indicating the order of execution and checkpoint information indicating whether or not it is necessary to observe the order of execution of the check processing indicated by the order information may be included. The second acquisition unit needs to protect the check point information stored in the second storage unit in association with the check item of the execution result input by the user in order of execution of the check processing. In the case of indicating that there is, the user only when the execution result of the check item corresponding to the order information indicating the order before the order indicated by the order information corresponding to the check item is acquired. You may acquire the said implementation result input by.

  According to this configuration, when the checkpoint information stored in the second storage unit in association with the check item of the execution result input by the user indicates that the order of execution of the check processes needs to be observed The second acquisition of the execution result input by the user is obtained only when the execution result of the check item corresponding to the order information indicating the order before the order indicated by the order information corresponding to the check item is acquired. Acquired by the department. In other words, when the execution result of the check item corresponding to the order information indicating the order before the order indicated by the order information corresponding to the check item is not acquired, the execution result input by the user is the second Not acquired by the acquisition unit. Therefore, for a check process that needs to observe the order of execution, it is possible to allow the user to observe the order of execution of the check process.

  Moreover, in the above-described work performance management system, the check item data stored in the second storage unit further includes the check process indicated by the check item associated with each of the plurality of check items. Optional input information indicating whether or not the implementation is optional may be included. The second acquisition unit needs to protect the check point information stored in the second storage unit in association with the check item of the execution result input by the user in order of execution of the check processing. In the case of indicating that there is a check item corresponding to the order information indicating the order before the order indicated by the order information corresponding to the check item, The execution result input by the user may be acquired only when the execution result of the check item indicating that the execution is not arbitrary is acquired.

  According to this configuration, when the execution of the check process is not arbitrary, it is possible to allow the user to observe the order of execution of the check process. In addition, check items for which the execution of the check process is optional can be set based on the arbitrary input information. Therefore, the person in charge of production management can secure the outline of the order of execution of necessary check processing while maintaining a certain degree of flexibility in the order of execution of check processing for work on the production line.

  Moreover, in the above-described work performance management system, the check item data stored in the second storage unit further includes the check process indicated by the check item associated with each of the plurality of check items. Optional input information indicating whether or not the implementation is optional may be included. When the product identifier received from the work terminal includes an additional code indicating a custom specification, the list creation unit is specified by an identifier obtained by removing the additional code from the product identifier. The check item list is created with the target product as the first product, and the optional input information indicating that the execution of the check process indicated by all the check items is optional as the optional input information It may be included in the item list.

  According to this configuration, when the product is a custom specification, a check item list of the base product is created. In addition, since the execution of all the check processes is arbitrary, it is possible to create a check item list for products that are not custom specifications and a check item list for products that have custom specifications in the same system.

  In the work performance management system described above, the check item data stored in the second storage unit further includes the feature indicated by the feature option item associated with each of the plurality of check items. Character information related to the option may be included. The character information is indicated by a part of the feature option items among the feature option items in which the model specification item of the model specification data of the first product belongs to one of the plurality of function feature items. A character representing the functional feature item to which the feature option item belongs when the feature option item is selected and the feature option item indicated by the remaining feature option item is not selected. It may include a character string in which a column and a character string representing the feature option item indicated to be selected by the model specification item are combined.

  According to this configuration, it is indicated that a feature option indicated by some of the feature option items belonging to any one of the plurality of function feature items is selected, and the remaining feature option items When it is indicated that the feature option indicated by is not selected, a character string representing the feature option item indicated to be selected is included in the check item data. For this reason, the feature of a product can be displayed as a character string. As a result, the user can easily confirm the contents of the check item data, such as whether or not the feature option is correctly selected.

  Further, in the above-described check list creation device, the check processing that is master information created based on the model specification data and the check item data and that is performed for any product that belongs to the product group The plurality of check items respectively indicating order, the order information provided corresponding to the plurality of check items and indicating the order of execution of the check processing, and the order information provided corresponding to the plurality of check items, respectively. Check-related information having checkpoint information indicating whether or not it is necessary to observe the order of execution of the check processing indicated by each, and each product provided corresponding to each of the plurality of check items and belonging to the product group Master information including model specification information indicating whether or not the check process is performed. A master information storage unit for storing a master information management unit for managing the master information may further comprise a. The master information storage unit includes first check related information as the check related information, first master information including first model specification information as the model specification information, and second check related information as the check related information. , Second master information including second model specification information may be stored as the model specification information. The second master information may be created by changing a part of the first master information. The master information management unit determines whether the first check related information and the second check related information other than the order information include the same content, and the first check related information The first integrated information including the contents included in the second check related information so as not to overlap may be generated. The master information management unit determines whether the same product is redundantly included in the first model specification information and the second model specification information, and the first model specification information and the second model specification are determined. The second integrated information including the products included in the information so as not to overlap may be generated. The master information management unit corresponds to the first check related information corresponding to each combination of the check item included in the first integrated information and each product included in the second integrated information. A first element indicating whether the check process indicated in the check item is executed, not executed, or the first check related information is not included in the first integrated information, and the second check related A difference composed of a second element indicating whether the check process indicated by the check item corresponding to the information is executed, not executed, or the second check related information is not included in the first integrated information Each vector may be generated. The master information management unit may generate difference information indicating a difference of the second master information with respect to the first master information for each product included in the second integrated information, using the difference vector.

  According to this configuration, it is determined whether or not the same content is redundantly included in the first check related information and the second check related information other than the order information. First integrated information including the contents included in the first check related information and the second check related information so as not to overlap is generated.

  If it is determined that the order of execution of the check processing is different and the contents are not the same in consideration of the order information, all the contents other than the order information are included in the first integrated information. become. In that case, the first integrated information becomes complicated.

  However, according to this configuration, even if the execution order of the check processing is different, if the contents other than the order information are the same, the same contents are duplicated in the first check related information and the second check related information. It is judged that it is included. Therefore, it is possible to prevent the first integrated information from becoming complicated.

  Moreover, according to this structure, the difference information which shows the difference of 2nd master information with respect to 1st master information for every product contained in 2nd integrated information using a difference vector is produced | generated. Therefore, when it is already known that the first master information has been correctly created, it is possible to easily determine whether the second master information has been correctly created by checking only the difference information. it can.

  In the check list creation apparatus described above, the check point information indicating that the order of execution of the check processes needs to be observed may be defined as first check point information. The master information management unit represents a group of check items divided for each first checkpoint information in the order indicated by the order information in the first check related information and the second check related information, respectively. Information may be generated. The master information management unit may determine whether or not the same information is duplicated in the first check related information and the second check related information within the same range of the group information.

  According to this configuration, in the first check related information and the second check related information, group information representing the check item group divided for each first check point information is generated in the order indicated by the order information. . It is determined whether or not the same information is included in the first check related information and the second check related information in the same range. For this reason, a determination can be made easily.

  In the check list creation apparatus described above, the check point information indicating that the order of execution of the check processes needs to be observed may be defined as first check point information. In the first check related information and the second check related information, the master information management unit includes the first check point information in both the first check related information and the second check related information, respectively. And when the contents corresponding to the first checkpoint information are the same, group information representing a check item group divided for each first checkpoint information may be generated. The master information management unit may determine whether or not the same information is duplicated in the first check related information and the second check related information within the same range of the group information.

  According to this configuration, in the first check related information and the second check related information, the first check point information exists in both the first check related information and the second check related information, respectively, and the first check point When the contents corresponding to the information are the same, group information representing a check item group divided for each first checkpoint information is generated. For this reason, even if the check point information is changed in the second master information with respect to the first master information, the group information is not shifted between the first check related information and the second check related information. As a result, it is possible to easily determine whether or not the same content is included in the first check related information and the second check related information in the same range.

  According to the present invention, it is possible to easily create a check sheet corresponding to the model specifications of individual products to be manufactured in a manufacturing line characterized by high-mix low-volume production.

<First Embodiment>
<Overview>
A production line of products produced by a plurality of processes, for example, a production line of a machine assembly factory, is divided into work areas called stations, and a series of work in the station is a unit of a process to be managed. .

  Hereinafter, a first embodiment according to the present invention will be described with reference to the drawings.

<Overall configuration>
FIG. 1 is a diagram schematically showing the overall configuration of the work performance management system 100. The work performance management system 100 includes a management server device 1000, a file server device 1800, a production management system 1900, a work terminal device 2000A, a work terminal device 2000B, a network 101, a radio base station 120A, and a radio base station 120B.

  In addition, in this specification, when referring generically, it shows with the reference symbol which abbreviate | omitted the suffix, and when referring to an individual structure, it shows with the reference symbol which added the suffix. Further, FIG. 1 shows two work terminal devices 2000A and 2000B, but more may be provided, and two radio base stations 120A and 120B are shown. However, more may be provided.

  The work terminal device 2000 is installed in one-to-one correspondence with the station. The work terminal device 2000A is provided in the station 1, and the work terminal device 2000B is provided in the station 2. The work terminal device 2000A includes a card reader 2500A, and the work terminal device 2000B includes a card reader 2500B.

  The work terminal device 2000 is connected to the management server device 1000 via the network 101 and the radio base station 120. The network 101 is a factory network, for example, a wired LAN (Local Area Network) compliant with the Ethernet (registered trademark) standard. The wireless base station 120 is, for example, a wireless LAN base station that conforms to the WiFi (registered trademark) standard.

  Stations 1 and 2 in FIG. 1 are work areas in the production line 110, respectively. In the stations 1 and 2, operations of processes assigned to the stations are performed. Therefore, in the case of a product produced by a plurality of processes, a station for that process is provided. In FIG. 1, the process performed at the station 2 is assumed to be a subsequent process of the process performed at the station 1. That is, in the production line 110, the work object such as an assembly machine processed at the station 1 is then processed at the station 2.

  A process instruction card 2510 is added to each work object. The process instruction card 2510 moves through the station together with the work object. The process instruction card 2510 describes information for specifying a work object. When the process instruction card 2510 is read by the card reader 2500, a check sheet is displayed on the work terminal device 2000. In the present embodiment, the production order number is used as information for specifying the work object. That is, the work in the station is distinguished by the manufacturing order number in which one completed product is a unit.

  Each worker who performs work at the station is assigned a worker ID (Identification Data). It is assumed that the worker includes a worker ID card 2610 on which the worker ID is described. In principle, the worker registers his / her worker ID in the work terminal device 2000 when entering the station, and deletes the registration of the worker ID when leaving the station. In FIG. 1, two workers are shown at station 1 and one worker is shown at station 2, but the number is not limited to this.

  When the worker reads the process instruction card 2510 attached to the work object flowing through the production line 110, for example, a part necessary for the assembly work, into the card reader 2500, the work terminal apparatus 2000 checks. A sheet is displayed. The process instruction card 2510 is issued for each manufacturing order number that is an identifier for specifying one completed product.

  The worker performs work such as assembly work according to the check sheet displayed on the work terminal device 2000, and when the work is completed, inputs the results of the work to the check sheet displayed on the work terminal device 2000. . The work results of each station input to each work terminal device 2000 are collected and managed in the management server device 1000.

<Check sheet>
FIG. 3 is a diagram illustrating an example of a check screen WIN displayed on the display unit 2300 (FIG. 2) of the work terminal device 2000.

  A check sheet 20 is displayed on the check screen WIN. In the upper left of the check screen WIN, the identification information 10 of the displayed check sheet 20 is displayed. In FIG. 3, the check sheet 20 of the product having the production order number “J040023”, the model “MS03-A1J”, and the production date “2014/10/1” is displayed by the identification information 10. I understand.

  When the worker reads the manufacturing order number “J040023” of the process instruction card 2510 using the card reader 2500 of the work terminal device 2000, a check screen WIN as shown in FIG. 3 is displayed on the display unit 2300 ( 2).

  The check sheet 20 includes seven items: a check item 21, an optional input item 22, an item type 23, an input field 24, an input time 25, an input person 26, and a related book 27.

  Of the seven items of the check sheet 20, the four items of the check item 21, the optional input item 22, the item type 23, and the related book 27 are items that are already set when the check sheet 20 is displayed. The three items of the input field 24, the input time 25, and the input person 26 are items that the worker inputs as work results. Specifically, when the worker inputs the work result in the input field 24, the work terminal device 2000 sets the time at the time of input to the input time 25 and sets the operator identifier to the input person 26.

  The check item 21 indicates a check process performed by the worker. Check items 21 are displayed from the top in the order in which the check processing is performed. The arbitrary input item 22 indicates whether or not the input to the input field 24 is arbitrary. “O” displayed as the optional input item 22 indicates that input to the input field 24 is optional. In other words, it is indispensable to perform the check process indicated by the check item 21 in the row where “◯” is not displayed as the optional input item 22. On the other hand, the check process indicated by the check item 21 in the row where “◯” is displayed as the optional input item 22 may not be performed.

  The item type 23 indicates the type of data to be input to the input field 24. For example, the operator inputs “re” (check mark) to the input field 24 in the row where “check” is displayed as the item type 23. In addition, the worker inputs a numerical value into the input field 24 in the row where “Numeric Value” is displayed as the item type 23.

  The input field 24 indicates the execution result of the check process indicated in the check item 21. The input time 25 indicates the time when the implementation result is input in the input field 24. The input person 26 indicates an operator who has input the execution result in the input field 24. The related book 27 indicates a related book name indicating a related book related to the check process shown in the check item 21, for example, a drawing, a work procedure manual, a test procedure manual, and the like. For example, when the operator wants to confirm the procedure for the check process indicated as “driving unit test run” as the check item 21, the “procedure 002” displayed as the related book 27 in the row is displayed as a mouse or the like. Select with. Then, another window is opened and the contents of the document file indicated by “procedure 002” are displayed.

  When performing assembly work, not only a check sheet, but also a work procedure manual and a test procedure document detailing the work are required. Prior to actual manufacturing work, workers are educated based on these books. However, during work on the production line 110, the worker may want to check these related books.

  However, since the operator cannot easily leave the production line 110, it has been difficult to confirm in the past. In the work performance management system 100, if the worker selects a related book name displayed in the related book 27 of the check sheet 20, the contents of a desired document file are displayed. For this reason, the operator can easily confirm the necessary work procedure manual and test procedure manual without leaving the production line 110. As a result, work quality is improved.

  The worker looks at the check item 21 on the check sheet 20 and grasps the procedure of the check processing work. When the work is completed, the worker inputs the record information in a predetermined format in the input field 24 according to the display contents in the optional input item 22 and the item type 23. For example, after specifying the input field 24 with a mouse, for example, double-clicking to input a check mark, or inputting a measurement value or text using a keyboard or the like, the result information is input to the input field 24. .

  With respect to the check sheet 20 displayed on the check screen WIN described above, the worker inputs result information regarding the work performed at his / her station. For example, the operator of the station 1 indicated by the identifier “Taro Shinko” performs the check processing indicated by the three check items 21 from the first to third lines of the check sheet 20, and records the results in the input field 24. The information is input and the work object is sent to the station 2.

  Then, when the worker of the station 2 of the next process reads the manufacturing order number “J040023” of the process instruction card 2510 using the card reader 2500 of the work terminal device 2000, the input field 24 as shown in FIG. The check sheet 20 on which the result information is displayed by the first to third lines is displayed. The operator of the station 2 performs the check process indicated by the fourth check item 21. In this way, the worker performs assembly work at each station on the parts and the like that are work objects flowing through the production line 110 to create a finished product.

<Configuration of management server device and work terminal device>

  The display unit 1300 includes an LCD or the like, for example, model specification data 3010 (FIG. 4) stored in the model specification information storage unit 3000, and check item data 3110 (FIG. 4) stored in the check item information storage unit 3100. 5) etc. are displayed.

  The operation unit 1400 includes a keyboard or the like, and is operated by a user for data input to the model specification data 3010 and the check item data 3110 displayed on the display unit 1300, for example.

  A model-specific item list creation unit 1600 (an example of a list creation unit) includes model specification data 3010 stored in the model specification information storage unit 3000 and check item data 3110 stored in the check item information storage unit 3100. Then, a model-specific check item list 3310 (FIG. 6) corresponding to the model of the ordered product specified by the production order number is created.

  The model-specific item list creation unit 1600 stores the created model-specific check item list 3310 in the model-specific item list storage unit 3300. The model specification data 3010 and the check item data 3110 are described in the section <Data>. A method for creating the model-specific check item list 3310 will be described in the section <Model-specific check item list creation method>.

  The work record collection unit 1700 reads the model-specific check item list 3310 corresponding to the manufacturing order number transmitted from the work terminal device 2000 from the model-specific item list storage unit 3300 and transmits it to the work terminal device 2000. The work record collection unit 1700 stores the work record information received from the work terminal device 2000 in the work record information storage unit 3400. The work record collection unit 1700 creates a work record table 3410. The work record collection unit 1700 stores the created work record table 3410 in the work record information storage unit 3400.

  The model specification information storage unit 3000 (an example of a first storage unit) stores a function for each model as model specification data 3010. The model specification data 3010 is created by a production engineer.

  The check item information storage unit 3100 (an example of a second storage unit) stores check items for each function as check item data 3110. The check item data 3110 is created by a production engineer.

  The input confirmation unit 1450 confirms the data input by the production engineer using the operation unit 1400 against the model specification data 3010 and the check item data 3110. The input confirmation unit 1450 creates model specification data 3010 and check item data 3110 based on the confirmed data input. The input confirmation unit 1450 stores the created model specification data 3010 in the model specification information storage unit 3000. The input confirmation unit 1450 stores the created check item data 3110 in the check item information storage unit 3100.

  The model-specific item list storage unit 3300 stores a model-specific check item list 3310 for each model. The model-specific check item list 3310 is created by the model-specific item list creation unit 1600 and stored in the model-specific item list storage unit 3300.

  The work record information storage unit 3400 stores a work record table 3410 for each manufacturing order number. The work record table 3410 is created by the work record collection unit 1700 and stored in the work record information storage unit 3400.

  The file server device 1800 (an example of a storage device) is communicably connected to the management server device 1000. The file server apparatus 1800 is communicably connected to the work terminal apparatus 2000 via the management server apparatus 1000. The file server apparatus 1800 stores and manages a document file (an example of a related document) related to the check process. For example, the document file is stored in a general-purpose format such as PDF (Portable Document Format).

  When the worker selects a related book name displayed in the related book 27 of the check sheet 20, the work terminal device 2000 transmits the related book name to the file server device 1800 via the management server device 1000. Upon receiving the related book name from the work terminal device 2000, the file server device 1800 reads the document file specified by the received related book name, and transmits the read document file to the work terminal device 2000.

  Note that the document file stored in the file server apparatus 1800 may be stored in the management server apparatus 1000. In this case, the work terminal apparatus 2000 transmits the related book name to the management server apparatus 1000. The management server apparatus 1000 reads the document file specified by the related book name received from the work terminal apparatus 2000, and transmits the read document file to the work terminal apparatus 2000.

  The production management system 1900 manages a plan from product order to delivery. Further, the production management system 1900 is connected to the management server device 1000 so as to be communicable. In the present embodiment, the production management system 1900 stores order information in which the production order number is associated with the ordered product (model). The production management system 1900 receives the manufacturing order number from the work terminal device 2000 via the management server device 1000.

<Data>
Hereinafter, data used in the work performance management system 100 will be described.

<Model specification information storage unit 3000>
FIG. 4 is a diagram showing a configuration example and contents example of the model specification data 3010. The model specification data 3010 indicates product specifications, is created by a production engineer, and is stored in the model specification information storage unit 3000. The model specification data 3010 is created for each product group of model specifications sharing a certain basic configuration. FIG. 4 shows an example of model specification data 3010 of the product group “MS03”.

  The model specification data 3010 includes a model 3011 and a specification item 3012. The model 3011 indicates a model identifier (an example of a product identifier) for specifying the type of product belonging to the product group “MS03”. That is, the model 3011 does not specify a finished product, but specifies the type of product. The finished product is specified by the production order number.

  The specification item 3012 indicates an item of a specification possessed by one of the products of the model indicated by the model 3011 (that is, a product belonging to the product group “MS03”). The specification item 3012 includes a plurality of function feature items 3013 representing features of the functions of the product. In FIG. 4, the specification item 3012 includes three function feature items 3013 of “product shape”, “control voltage”, and “sales area”.

  The function feature item 3013 includes a feature option item 3014 indicating a choice of the feature. In FIG. 4, among the functional feature items 3013, “product shape” includes three feature option items 3014 of “type A”, “type B”, and “type C”, and “control voltage” is “100 V”. , “200V” and “400V” three feature option items 3014, and “Sales District” includes three feature option items 3014 “Domestic”, “Asia” and “Europe”.

  The product indicated by each model identifier has an element (an example of a model specification item) in the two-dimensional matrix defined by the model identifier row indicated by the model 3011 and the column of the feature option item 3014. Features are shown. The element for which “1” is set indicates that the feature option indicated by the feature option item 3014 in the column is selected by the product indicated by the model identifier in the row, and “0” is set. Indicates that the feature option indicated by the feature option item 3014 in the column is not selected.

  When the person in charge of production engineering creates model specification data 3010, first, the model specification is used to indicate the function feature indicating the difference in the specifications of each model identifier (product) indicated by the model 3011 and the feature options included in each function feature. Select as Then, the person in charge of production engineering registers in what combination the specification of each model identifier (product) indicated by each model 3011 is specified by each feature option indicated by the feature option item 3014. In other words, the production engineer sets “1” or “0” to all elements in the two-dimensional matrix defined by the model identifier row indicated by the model 3011 and the column of the feature option item 3014.

  The input confirmation unit 1450 uses the operation unit 1400 to confirm data input to the elements in the two-dimensional matrix by the production engineer. If the input data is “1” or “0” as a result of the confirmation, the input confirmation unit 1450 accepts the input data. On the other hand, as a result of the confirmation, the input confirmation unit 1450 does not accept the input data unless the input data is “1” or “0”. In this case, the input confirmation unit 1450 may display a message on the display unit 1300, for example, to alert the user. The input confirmation unit 1450 creates the model specification data 3010 according to the input data by the production engineer.

  FIG. 4 shows an example in which a function feature item 3013 is provided for the product group “MS03”, which indicates different function features depending on the difference between “product shape”, “control voltage”, and “sales district”. Yes. In each function feature item 3013, a feature option item 3014 in which “1” is set represents the selected feature.

  For example, in the model identifier of the model 3011 of “MS03-A1J”, the “product shape” of the function feature item 3013 is an element of “type A”, the “control voltage” is an element of “100 V”, and the “sales district” is “ “1” is set for each element of “Domestic”. For this reason, the specification of the product of this model identifier has the shape of type A, the control voltage is 100 V (volt), and it can be seen that this is a domestic sales model.

  In the present embodiment, it is assumed that only one feature option item 3014 is selected in each function feature item 3013 (“1” is set) as the product specification of each model identifier.

<Check item information storage unit 3100>
FIG. 5 is a diagram illustrating a configuration example of the check item data 3110 and a content example thereof. The check item data 3110 is a list of check items, created by a production engineer, and stored in the check item information storage unit 3100. The check item data 3110 is created for each product group of model specifications sharing a certain basic configuration. FIG. 5 shows an example of the check item data 3110 of the product group “MS03”.

  The check item data 3110 includes an item number 3111, a check item 3112, an item type 3113, a related book 3114, an arbitrary input item 3115, a check point 3116, an application pattern 3117, and a specification item 3118. The specification item 3118 includes a function feature item 3119. The function feature item 3119 includes a feature option item 3120.

  A check item 3112 indicates the content of the check process to be performed. The item number 3111 (an example of order information) indicates the order in which the check processing indicated by the check item 3112 is performed, and is set in ascending order from 1. In the check item data 3110, one check process is registered as one record. Therefore, it can be said that the item number 3111 is a number that specifies the check process indicated by the check item 3112.

  The item type 3113 indicates the type of result information of the check process indicated by the check item 3112. Specifically, the item type 3113 indicates the type of data input to the input field 24 of the check sheet 20 (see FIG. 3).

  In the item type 3113, “check” indicates that “re” indicating that the content of the check process indicated by the check item 3112 has been performed is input. For example, when the check item 3112 is “confirm that there is no missing part in the assembly part”, “re” is input when it is confirmed that there is no missing part.

  In the item type 3113, “S / N” indicates that a serial number as a result of performing the contents of the check process indicated by the check item 3112 is input. For example, when the check process indicated by the check item 3112 is “motor serial number confirmation (100V / 200V)”, the motor serial number is input.

  In the item type 3113, “numerical value” indicates that a value obtained as a result of performing the content of the check process indicated by the check item 3112 is input. For example, when the check process indicated by the check item 3112 is “measure control voltage value (100 V)”, the control voltage of the product is measured, and the control voltage value that is the result is input. In the item type 3113, “text” indicates that a character string such as a comment related to the check process indicated by the check item 3112 is input.

  A related book 3114 (an example of a document identifier) indicates a related book name for identifying a related book related to the check process indicated by the check item 3112, for example, a drawing name, a procedure book name, and the like.

  The optional input item 3115 (an example of optional input information) indicates whether the execution of the check process indicated by the check item 3112 is indispensable or optional. In the optional input item 3115, “0” indicates that the execution of the check process is essential, and “1” indicates that the execution of the check process is optional.

  In the check processing, for example, a check item 3112 “special notes” of a record whose item number 3111 is “26” requires input if there is something, but it does not necessarily require input. In such a case, the execution of the check process indicated by the check item 3112 in which “1” is set in the optional input item 3115 is optional.

  A check point 3116 (an example of check point information) indicates a timing condition for performing the check process indicated by the check item 3112. Specifically, the check process indicated in the check item 3112 of the record in which “1” is set as the check point 3116 is a record in which a number smaller than the number set as the item number 3111 of this record is set. It is not possible to execute it until after all the check processes are completed.

  For example, in the check process “driving unit main body final confirmation” indicated in the check item 3112 of the record with the item number 3111 of “25”, the check process of the records with the item numbers 3111 of “1” to “24” must be performed. If it is, it cannot be implemented.

  However, it does not matter whether or not the check process for the record whose optional input item 3115 is “1” has been completed. That is, even if the record of the check process of the record whose optional input item 3115 is “1” is not input to the check sheet 20, the operator records “1” as the check point 3116. The check record 20 can be input to the check sheet 20.

  In the case of product assembly close to custom production, especially in the case of product assembly close to custom production, the specific execution order of individual work is not specified, and it is left to the discretion of the operator, or a part of the work depends on the model specification. In some cases, the process may be performed separately on the partial assembly line. In order to cope with such a case, the present embodiment introduces a mechanism for restricting the check process while allowing the check process to be performed in some order.

That is, the worker may not necessarily input the work results to be input to the check sheet 20 in a predetermined order. Specifically, as described above, the check item data 3110 is provided with an item called a check point 3116 and the following restrictions are provided.
(I) For a check item in which “0” is set at the check point 3116, the work results can be input even if all of the previous check items (item number 3111 is smaller) have not been completely input.
(Ii) For check items for which “1” is set at the check point 3116, the work results cannot be input unless all of the previous check items (item number 3111 is smaller) have been input.
(Iii) If a work record is not input for a check item for which “1” is set at the check point 3116, the work record cannot be input for a check item after that.

  In other words, the check items in which “0” is set at the check point 3116 may be changed in the execution order at the discretion of the operator. Due to this restriction, it is possible to ensure a necessary work order outline while maintaining a certain degree of work order flexibility.

  An application pattern 3117 (an example of character information) indicates an explanation of what type of specifications the check process indicated by the check item 3112 is applied to. Specifically, the application pattern 3117 includes a character string in which a character string representing the function feature item 3119 and a character string representing the feature option item 3120 are connected.

  The specification item 3118 indicates an item having the same specification as the specification item 3012 of the model specification data 3010 (see FIG. 4). The specification item 3118 includes a function feature item 3119 representing the feature of the function of the product. The function feature item 3119 includes a feature option item 3120 indicating a choice of the feature.

  Each check item is associated with an element (an example of an execution selection item) in the two-dimensional matrix defined by the row of the check process indicated by the check item 3112 and the column of the feature option item 3120 of the specification item 3118. Whether or not the check processing indicated by 3112 is executed is shown.

  An element for which “1” is set indicates that the check process indicated by the check item 3112 in the row is performed for the feature option indicated in the feature option item 3120 in the column. An element for which “0” is set indicates that the check process indicated by the check item 3112 in the row is not performed for the feature option indicated in the feature option item 3120 in the column.

  When the production engineer creates the check item data 3110, it is registered whether the check process indicated by the check item 3112 is a check process executed for the feature option indicated by which feature option item 3120. To do. That is, the production engineer sets “1” or “0” to all elements in the two-dimensional matrix defined by the check processing row indicated by the check item 3112 and the column of the feature option item 3120. To do.

  The input confirmation unit 1450 uses the operation unit 1400 to confirm data input to the elements in the two-dimensional matrix by the production engineer. If the input data is “1” or “0” as a result of the confirmation, the input confirmation unit 1450 accepts the input data. On the other hand, as a result of the confirmation, the input confirmation unit 1450 does not accept the input data unless the input data is “1” or “0”. In this case, the input confirmation unit 1450 may display a message on the display unit 1300, for example, to alert the user. The input confirmation unit 1450 creates check item data 3110 according to the input data by the production engineer.

  When the production engineer creates the check item data 3110, values (that is, “1” or “1” set in the elements of the two-dimensional matrix defined by the row of the check item 3112 and the column of the feature option item 3120. If “0”) is mistaken, the necessary check item 3112 may not be displayed or the unnecessary check item 3112 may be displayed, which may cause confusion at the site.

  Therefore, in the present embodiment, when each element of the matrix of the check item data 3110 is set, the input confirmation unit 1450 sets both “0” and “1” as the elements of the feature option item 3120 for each record. A character string is created by combining the name of the function feature item 3119 to be included and the set of names of the feature option item 3120 in which “1” is set among the feature option items 3120 belonging to the function feature item 3119. The input confirmation unit 1450 sets the created character string as the application pattern 3117. As a result, the production engineer can check whether or not the correct feature option item 3120 has been selected by referring to the character string set as the application pattern 3117.

  The name of the functional feature item 3119 including both “0” and “1” as the elements of the feature option item 3120 is used when all the elements of the feature option item 3120 are “1”. This is because even if the name of the function feature item 3119 is displayed, it does not check the selection error of the feature option item 3120.

  For example, in the record in which the item number 3111 of FIG. 5 is “3”, the element is set to “0” because the feature option item 3120 whose function feature item 3119 is “control voltage” is “400V”. Therefore, the input confirmation unit 1450 includes the name “control voltage” of the function feature item 3119 and the name “100 V” of the feature option item 3120 in which “1” is set among the feature option items 3120 belonging to the function feature item 3119. A character string “control voltage: 100 V, 200 V” combined with a set of “200 V” is set as the application pattern 3117.

  In addition, when “1” is set in all the feature option items 3120, the input confirmation unit 1450 sets the character string “common” as the application pattern 3117.

  As described above, in this embodiment, when the setting of the feature option item 3120 for each check item 3112 is input, the application target represented by the number “1” or “0” to the element of the two-dimensional matrix is displayed. , “Control voltage: 400V Sales area: Asia”, etc., are displayed in the application pattern 3117 in a more easily recognized Japanese character string. Therefore, the person in charge of production technology can more intuitively collate his / her intention of input with “1” or “0” actually input to the element, so that setting errors can be reduced. .

<Model-specific item list storage unit 3300>
FIG. 6 is a diagram illustrating a configuration example of the model-specific check item list 3310 and a content example thereof. The model-specific check item list 3310 is a check item list corresponding to the model. The model-specific item list creation unit 1600 creates a model-specific check item list 3310. The model-specific item list creation unit 1600 stores the created model-specific check item list 3310 in the model-specific item list storage unit 3300.

  The model-specific check item list 3310 is transmitted to the work terminal device 2000 by the work record collection unit 1700. The work terminal device 2000 creates the check sheet 20 based on the received model-specific check item list 3310 and displays the created check sheet 20 on the display unit 2300. FIG. 6 shows an example of the model-specific check item list 3310 of the product “MS03-A3A” of the production order number “J040099”.

  The model-specific check item list 3310 includes an item number 3311, a check item 3312, an item type 3313, a related book 3314, an optional input item 3315, and a check point 3316.

  Item number 3311, check item 3312, item type 3313, related book 3314, optional input item 3315, check point 3316 are item number 3111, check item 3112, item type 3113, related book of check item data 3110 (FIG. 5). This item is the same as 3114, optional input item 3115, and checkpoint 3116.

  A check item 3312 indicates the content of the check process. The item number 3311 specifies the check process indicated by the check item 3312 and indicates the order of the check process. The item type 3313 indicates the work performance type of the check process indicated by the check item 3312. The related book 3314 indicates the name of a related book related to the check process indicated by the check item 3312. The optional input item 3315 indicates whether the execution of the check process indicated by the check item 3312 is essential or optional.

  A check point 3316 indicates whether or not the order in which the check processing is performed needs to be observed. That is, in the check process indicated in the check item 3312 of the record in which “1” is set as the check point 3316, a number smaller than the number set as the item number 3311 of this record is set as the item number 3311. It must be done after all of the records that have been checked are complete.

  The model-specific check item list 3310 is different from the check item data 3110 in that the application pattern 3117 and the specification item 3118 included in the check item data 3110 are not provided.

  In the check item data 3110, check processing performed for any of the products belonging to the product group “MS03”, in other words, all check processing is registered. Only the check process of the product “MS03-A3A” is registered. Accordingly, the check item data 3110 contains a record with an item number 3111 in which an ascending number is set from “1”, but the model-specific check item list 3310 requires a record as shown in FIG. Only the record of the item number 3311 in which the number of the check process is set is registered.

<How to create model-specific check item list>
Here, a method in which the model-specific item list creation unit 1600 creates the model-specific check item list 3310 will be described.

  FIG. 7 is a diagram for explaining a method for creating the model-specific check item list 3310. In FIG. 7, consider a case where the model-specific item list creation unit 1600 creates a model-specific check item list 3310 for products whose model 3011 of the model specification data 3010 is “MS03-A3A”.

  The model-specific item list creation unit 1600 determines a check process to be performed on a product whose model 3011 is “MS03-A3A” from the model specification data 3010 and the check item data 3110, and stores the item number correspondence table 720 in the work memory. To create.

  In this item number correspondence table 720, “item number” corresponds to the item number 3111 of the check item data 3110, and “MS03-A3A” checks the item number 3111 of the check item data 3110 corresponding to “item number”. The determination result of whether or not the process is performed on the product whose model 3011 is “MS03-A3A” is shown.

  When “MS03-A3A” is “1”, it indicates that the check process for the corresponding item number 3111 is performed. When “MS03-A3A” is “0”, the check process for the corresponding item number 3111 is performed. Indicates that no action is taken.

  The model-specific item list creation unit 1600 determines whether check processing is performed for all “item numbers”, and creates this item number correspondence table 720. In the model-specific item list creation unit 1600, the same number as the “item number” in which “1” is set as “MS03-A3A” in the item number correspondence table 720 is set as the item number 3111. A record is read from the check item data 3110 to create a model-specific check item list 3310.

  Hereinafter, a method in which the model-specific item list creation unit 1600 determines whether to perform the check process in which the item number 3111 of the check item data 3110 is “4” will be described.

  The model-specific item list creation unit 1600 first reads a record in which “MS03-A3A” is set as the model 3011 from the model specification data 3010 (see the broken arrow 721), and the model 3011 and its feature option item 3014 A logical value 710 set as an element in the matrix is extracted. Further, the model-specific item list creation unit 1600 extracts the logical value 709 of the element of the record in which “4” is set as the item number 3111 of the check item data 3110. The model-specific item list creation unit 1600 obtains a logical product 711 of the logical value 710 and the logical value 709.

  Next, the model-specific item list creation unit 1600 obtains the logical sum 712 for each functional feature item 3119 of the specification item 3118, that is, every three logical values, for the obtained logical value of the logical product 711. Then, the model-specific item list creation unit 1600 obtains a logical product 713 for the obtained logical value of the logical sum 712. The logical value of the logical product 713 indicates whether or not to check the item number 3111 of “4” for the model “MS03-A3A”. When the logical value of the logical product 713 is “1”, a check process with an item number 3111 of “4” is performed, and when “0”, the check process is not performed. In FIG. 7, since the logical value of the logical product 713 is “0”, “0” is set in correspondence with “4” of “item number” in the item number correspondence table 720 (dotted line arrow 722). reference).

<Work result information storage unit 3400>
FIG. 8 is a diagram illustrating a configuration example and a content example of the work performance table 3410. The work result table 3410 is for managing work results. The work record table 3410 is created by the work record collection unit 1700 for each manufacturing order number and is stored in the work record information storage unit 3400. In the work record table 3410, the work record input by the worker on the check sheet 20 (see FIG. 3) displayed on the work terminal device 2000 is added as one record per check item by the work record collection unit 1700. . FIG. 8 shows an example of the work result table 3410 of the production order number “J040023”.

  The work record table 3410 includes a production order number 3411, an item number 3412, an item type 3413, an input record 3414, an input time 3415, and an input person 3416.

  The production order number 3411 indicates which production order number the product of which the work result table 3410 is. The item number 3412 indicates a number for specifying a check item (check process). The item type 3413 indicates the type of work performance of the check process specified by the item number 3412.

  The input result 3414 indicates the result of the check process indicated by the check item specified by the item number 3412 for the product with the manufacturing order number 3411. This result is input by the operator as the input field 24 of the check sheet 20 (see FIG. 3).

  The input time 3415 indicates the time when the check result indicated by the input result 3414 is input to the check sheet 20 by the operator, that is, the time displayed as the input time 25 of the check sheet 20. In other words, the input time 3415 indicates the time when the check process was performed.

  The input person 3416 indicates the identifier of the worker who performed the check processing of the check item indicated by the item number 3412. This identifier is displayed as the input person 26 of the check sheet 20.

  The product with the production order number 3411 flows through the station. When the check process indicated by the check item is performed by the worker, the work result is input to the check sheet 20. When the work at the station is completed, a record is added to the work result table 3410 based on the input result of the check sheet 20.

<Storage Unit of Production Management System 1900>
FIG. 9 is a diagram illustrating a configuration example of the order information table 1910 and a content example thereof. The order information table 1910 is data stored and managed in a storage unit in the production management system 1900. When the production management system 1900 receives the manufacturing order number from the work terminal device 2000 via the management server device 1000, the production management system 1900 refers to the order information table 1910 and sets the model specification corresponding to the manufacturing order number to the work terminal device 2000. Send to.

  The order information table 1910 includes a production order number 1911 and a model 1912. The production order number 1911 (an example of a product identifier) is an identifier for specifying an order from a customer. The model 1912 indicates an identifier that identifies the model of the product requested to be manufactured by the order indicated by the identifier of the manufacturing order number 1911.

  In FIG. 9, “MS03-A1J-C” of the model 1912 indicates that the product is manufactured with a custom specification according to an order. The additional code “C” indicates a custom specification. “MS03-A1J-C” indicates a custom specification based on the model “MS03-A1J”. The model “MS03-A1J” is an example of a target product specified by an identifier obtained by removing an additional code from a product identifier.

  When the code “C” indicating the custom specification is added to the end of the identifier indicated by the model 1912, the model-specific item list creation unit 1600 creates a model-specific check item list 3310 applied to the base model. Then, the model-specific item list creation unit 1600 sets “1” as the arbitrary input item 3315 of the created model-specific check item list 3310.

  For products with custom specifications, the model-specific item list creation unit 1600 distributes the model-specific check item list 3310 created in this way to the work terminal device 2000 and displays the check sheet 20 to display all check items. Operate as an optional input item. In other words, even if the ordered product is a custom specification, most of the check items to be implemented with the base model specification are utilized for the electronic effect, and the check processing is not required for the check items that are not performed by the custom manufacturing instruction. it can. Therefore, the work result management system 100 can handle an ordered product that is not registered as the model 3011 in the model specification data 3010.

  Conventionally, for custom models that are not registered in the model specification data 3010, a custom manufacturing instruction is issued separately from the registered models, new check items are added, and unnecessary check items are deleted. In many cases, it is necessary to perform the work. However, the work performance management system 100 according to the present embodiment uses all check items as arbitrary check items in a custom model. This makes it possible to handle products that are not normal custom specifications and products with custom specifications. In the present embodiment, for custom products, “1” is set as all the optional input items 3315 in the model-specific check item list 3310, but for check items that are not implemented by the custom manufacturing instruction sheet. Only “1” may be set.

<Operation>
Hereinafter, operation | movement of the work performance management system 100 is demonstrated using FIGS. 10-12.

  10 is a flowchart of the work record collection process, FIG. 11 is a flowchart of the check item list creation process, and FIG. 12 is a flowchart of the work record input process. In the flowchart of FIG. 10, broken line arrows indicate the flow of data.

  First, the work performance collection process in FIG. 10 will be described. When an operator enters a station where work is scheduled to be performed, the operator logs in to the work terminal device 2000 installed in the station. Specifically, the worker ID acquisition unit 2600 of the work terminal device 2000 reads the worker ID of the worker ID card 2610 possessed by the worker ID card 2610. The worker ID acquisition unit 2600 notifies the control unit 2100 of the read worker ID. Receiving the notification, the control unit 2100 stores the notified worker ID in the work memory.

  When the work object flows through the production line 110, the operator who has logged in the work terminal device 2000 uses the card reader 2500 to obtain the “manufacturing order number” of the process instruction card 2510 attached to the work object. Read. The card reader 2500 that has read the “manufacturing order number” notifies the control unit 2100 of the read “manufacturing order number” (step S10). Upon receiving the notification, the control unit 2100 transmits the notified “manufacturing order number” to the management server apparatus 1000 via the communication unit 2200 (step S11).

  When the control unit 1100 of the management server apparatus 1000 receives the “manufacturing order number” via the communication unit 1200, the model-specific check item list 3310 of the product model specified by the received “manufacturing order number” has been created. It is determined whether or not there is (step S20). In other words, the model-specific check item list 3310 is not created for the model that is first manufactured on the production line 110. The control unit 1100 determines that the product type check item list 3310 of the product specified by the “manufacturing order number” is stored in the model type item list storage unit 3300 (step S20). YES), the process of step S23 is executed.

  On the other hand, if the model-specific check item list 3310 of the product specified by the “manufacturing order number” is not stored in the model-specific item list storage unit 3300, it is determined that it has not been created (NO in step S20). The control unit 1100 transmits the “manufacturing order number” received from the work terminal apparatus 2000 to the production management system 1900 (step S21).

  The production management system 1900 that has received the “manufacturing order number” from the management server apparatus 1000 is identified by the received “manufacturing order number” with reference to the order information table 1910 (see FIG. 9) stored in the storage unit. Find the model identifier of the product. Specifically, in the order information table 1910, the model identifier set as the model 1912 is read in the record in which the received “production order number” is set as the manufacturing order number 1911. In the example of FIG. 9, when the “manufacturing order number” is “J040023”, the model identifier is “MS03-A1J-C”. The production management system 1900 transmits the obtained model identifier to the management server apparatus 1000 (step S30).

  Upon receiving the model identifier from the production management system 1900, the control unit 1100 of the management server apparatus 1000 passes the received model identifier to the model-specific item list creation unit 1600 to create a model-specific check item list 3310 (see FIG. 6). Request. Upon receipt of the request, the model-specific item list creation unit 1600 creates a model-specific model item check item list 3310 (step S22).

  Here, the model-specific check item list creation process (step S22 in FIG. 10) will be described with reference to FIG.

  The model-specific item list creation unit 1600 receives a model identifier from the control unit 1100 (step S40). Subsequently, in step S41, the model-specific item list creation unit 1600 includes model specification data 3010 stored in the model specification information storage unit 3000 and check item data 3110 stored in the check item information storage unit 3100. Referring to the above-described <Model-specific check item list creation method>, the check items to be performed for the product indicated by the received model identifier are extracted (see the item number correspondence table 720 in FIG. 7). At this time, if the code “C” indicating the custom specification is added to the end of the model identifier received from the control unit 1100, the model-specific item list creation unit 1600 excludes “−C” and sets the base and Check items are extracted for the model.

  Next, the model-specific item list creation unit 1600 determines whether or not a code “C” indicating the custom specification is added to the end of the model identifier received from the control unit 1100 (step S42). When the code “C” indicating the custom specification is added (YES in step S42), the “item number” in which “1” is set in the item number correspondence table 720 of FIG. The record in which the same number as the item number is set as the item number 3111 is read, the model-specific check item list 3310 is created, and “1” is set as the arbitrary input item 3315 of all the records (step S44).

  On the other hand, when the code “C” indicating the custom specification is not added to the end of the model identifier received from the control unit 1100 (NO in step S42), the model-specific item list creation unit 1600 displays the model-specific check item list. 3310 is created (step S43).

  Then, the model-specific item list creation unit 1600 that has created the model-specific check item list 3310 stores the created model-specific check item list 3310 in the model-specific item list storage unit 3300 and notifies the control unit 1100 to that effect. This completes the check item list creation process in step S22 of FIG.

  Next, in step 23 in FIG. 10, the control unit 1100 passes the “manufacturing order number” received from the work terminal device 2000 and the model identifier received from the production management system 1900 to the work result collection unit 1700, Request collection of achievements.

  The work performance collection unit 1700 that has received the request reads the model-specific check item list 3310 of the model identifier passed from the control unit 1100 from the model-specific item list storage unit 3300 and transmits it to the work terminal device 2000 (step S23). . When the work record table 3410 of the “manufacturing order number” received from the work terminal device 2000 is stored in the work record information storage unit 3400, the work record collection unit 1700 reads the work record table 3410. To the work terminal device 2000. That is, the work result table 3410 is also transmitted to the work terminal devices 2000 of the second and subsequent stations.

  When receiving the model-specific check item list 3310 from the management server apparatus 1000, the control unit 2100 of the work terminal apparatus 2000 performs work result input processing (step S12). The work terminal devices 2000 of the second and subsequent stations also receive the work performance table 3410.

  Here, the work record input process (step S12 in FIG. 10) will be described with reference to FIG. The control unit 2100 receives the model-specific check item list 3310 and the work result table 3410 from the management server apparatus 1000 (step S50). Next, the control unit 2100 creates the check sheet 20 based on the model-specific check item list 3310 and the work performance table 3410, and displays the created check sheet 20 on the display unit 2300 (step S51). Specifically, the control unit 2100 includes a check sheet 20 including seven items: a check item 21, an optional input item 22, an item type 23, an input field 24, an input time 25, an input person 26, and a related book 27. The screen WIN (see FIG. 3) is displayed on the display unit 2300.

  The control unit 2100 displays the check processing indicated in the check item 3312 of each record in the model-specific check item list 3310 on the check item 21 in each row of the check sheet 20 in the order of records. In addition, the control unit 2100 displays “◯” in the arbitrary input item 22 in the row of the check sheet 20 corresponding to the record in which “1” is set in the arbitrary input item 3315 of the model-specific check item list 3310.

  The control unit 2100 displays the work performance input type set in the item type 3313 of each record in the model-specific check item list 3310 in the item type 23 of each row of the check sheet 20. The control unit 2100 displays the related book name set in the related book 3314 of each record of the model-specific check item list 3310 in the related book 27 of each row of the check sheet 20.

  In addition, the control unit 2100 displays the contents of each record of the work performance table 3410 in the corresponding item of the check sheet 20. Specifically, the control unit 2100 sets the work record set in the input record 3414 of each record in the work record table 3410, the time set in the input time 3415, and the worker ID set in the input person 3416. Are displayed on the input field 24, the input time 25, and the input person 26 in the row corresponding to the number set in the item number 3412 of the record.

  The control unit 2100 that has displayed the check sheet 20 on the check screen WIN of the display unit 2300 determines an input item to the operator's check sheet 20 via the operation unit 2400 (step S52).

  When the control unit 2100 determines that the related book name of the related book 27 of the check sheet 20 has been selected (“related book” in step S52), the file server device receives the selected related book name via the management server device 1000. 1800. Receiving the related book name from the work terminal device 2000, the file server device 1800 reads the document file specified by the received related book name, and transmits the read document file to the work terminal device 2000. Upon receiving the document file from the file server apparatus 1800, the control unit 2100 opens a window on the display unit 2300 and displays the received document file (step S53).

  If the control unit 2100 determines in step S52 that data has been input in the input area of the input field 24 of the check sheet 20 (“input field” in step S52), can the input be performed in the input area? It is determined whether or not (step S54).

  Specifically, in the control unit 2100, “0” is set in the check point 3316 of the record in the model-specific check item list 3310 corresponding to the input row of the input area (hereinafter referred to as “input row”). In this case, it is determined that input is possible.

  However, even when “0” is set in the check point 3316 of the record of the model-specific check item list 3310 corresponding to the input line, the control unit 2100 does not input a work record above the input line. If “1” is set in the check point 3316 of the record of the model-specific check item list 3310 corresponding to the row, it is determined that the input is impossible.

  In addition, when “1” is set in the check point 3316 of the record of the model-specific check item list 3310 corresponding to the input line, the control unit 2100 has work results in all lines above the input line. If it is input, it is determined that input is possible.

  In addition, the control unit 2100 operates when the check point 3316 of the record of the model-specific check item list 3310 corresponding to the input line is set to “1”, and the work is performed on any line above the input line. If no record is entered, it is determined that input is possible if the line that has not been input is a line of an optional input item, and input is impossible if the line is not a line of an optional input item. .

  The control unit 2100 determines whether or not the line is a line of an arbitrary input item, based on a value set in the arbitrary input item 3315 of the record of the model-specific check item list 3310 corresponding to the line. If “1” is set in the arbitrary input item 3315, the control unit 2100 determines that the line is an arbitrary input item, and if “0” is set, the control unit 2100 determines that the line is not an arbitrary input item.

  If the control unit 2100 determines that input is impossible (NO in step S54), the control unit 2100 displays an error message on the display unit 2300, and returns the process to step S52.

  Furthermore, the control unit 2100 may determine whether or not the type of the input data matches the type displayed as the item type 23 of the input line in step S54. If the control unit 2100 determines that they do not match (for example, an alphabet is entered in the input field 24 where the item type 23 is a numerical value) (NO in step S54), an error message is displayed on the display unit 2300, and the process is performed. You may return to step S52.

  If it is determined in step S54 that the input area into which the data has been input can be input (YES in step S54), the control unit 2100 acquires the current time from a timer (not shown), and checks the check sheet 20 The acquired time is written in the input time 25 of the input line, and the worker ID stored in the work memory is written in the input person 26 of the input line of the check sheet 20 (step S55).

  Subsequently, the control unit 2100 determines whether or not the worker ID is stored in the work memory (step S56). If the worker ID is stored in the work memory (YES in step S56), the process proceeds to step S58.

  On the other hand, when the worker ID is not stored in the work memory (NO in step S56), the control unit 2100 displays a message for the worker on the display unit 2300, and the worker ID card 2610 possessed by the worker. Is instructed to be read by the worker ID acquisition unit 2600 of the work terminal device 2000 to acquire the worker ID (step S57). The control unit 2100 stores the acquired worker ID in the work memory and writes it to the input person 26 in the input row of the check sheet 20.

  When the worker indicated by the worker ID stored in the work memory is not qualified to perform the check process, the control unit 2100 transfers the worker ID to another worker who is qualified to perform the check process. It is good also as inputting. In this case, the control unit 2100 stores, for example, the worker ID and the qualified check process in the work memory in association with each other.

  In step S <b> 58, the control unit 2100 determines whether or not the operator has performed an operation to end the operation using the operation unit 2400. For example, when it is detected that the operator has performed an end operation such as pressing a predetermined button (YES in step S58), the control unit 2100 advances the process to step S59. Further, when it is not detected that the worker has performed an operation to end the work (NO in step S58), the control unit 2100 returns the process to step S52.

  In step S59, the control unit 2100 displays the data displayed in the item type 23, the input field 24, the input time 25, and the input person 26 of one or more input lines of the check sheet 20 in which the operator inputs the work results; The item number set in the item number 3311 of the record of the model-specific check item list 3310 corresponding to the input row and the “manufacturing order number” of the work object are transmitted to the management server apparatus 1000 as work result data. . This completes the work record input process in step S12 of FIG.

  Next, in step 24 of FIG. 10, when the work record collection unit 1700 of the management server apparatus 1000 receives the work record data from the work terminal apparatus 2000, it creates a record from the received work record data, and creates a work record table 3410. (See FIG. 8). Specifically, the work record collection unit 1700 sets “manufacturing order number” as the manufacturing order number 3411 and sets the item number as the item number 3412 for each item number of the data received as the work record data. Data of type 23 is set as item type 3413, data of input field 24 is set as input result 3414, data of input time 25 is set as input time 3415, and data of input person 26 is set as input person 3416. A record is created and added to the work record table 3410.

Second Embodiment
In the first embodiment, when the manufacturing order number is received from the work terminal device 2000, the model-specific item list creation unit 1600 of the management server apparatus 1000 performs the model-specific check item based on the model specification data 3010 and the check item data 3110. A list 3310 is to be created. On the other hand, the second embodiment is different in that the check items to be performed are determined and stored in advance for all models belonging to the target product group.

  Therefore, in the processing of the second embodiment, the model-specific item list creation unit 1600 refers to the model-specific check item list table 3210 (FIG. 14 described later) and corresponds to the product model specified by the manufacturing order number. Only the point that the model-specific check item list 3310 is created is different from the processing of the first embodiment (see FIGS. 10 to 12). Only differences from the first embodiment will be described below.

  FIG. 13 is a block diagram illustrating functions of the management server device 1000, the file server device 1800, the production management system 1900, and the work terminal device 2000 according to the second embodiment. As shown in FIG. 13, the configuration of the management server device 1000 of the second embodiment includes a model-specific check item list creation unit 1500 and a model-specific check item list storage unit 3200 in the management server device 1000 of the first embodiment. It is added.

  FIG. 14 is a diagram illustrating a configuration example and contents example of the model-specific check item list table 3210. The model-specific check item list table 3210 is a check item list of all models belonging to the product group. The model-specific check item list creation unit 1500 creates the model-specific check item list table 3210 and stores the created model-specific check item list table 3210 in the model-specific check item list storage unit 3200 (an example of a master information storage unit). . FIG. 14 shows an example of the model-specific check item list table 3210 of the product group “MS03”.

  The model-specific check item list table 3210 (an example of master information) includes an item number 3211, a check item 3212, an item type 3213, a related book 3214, an optional input item 3215, a check point 3216, an application pattern 3217, and a model specification 3218. Prepare.

  Item number 3211, check item 3212, item type 3213, related book 3214, optional input item 3215, check point 3216, application pattern 3217 are item number 3111, check item 3112, item type of check item data 3110 (FIG. 5). This item is the same as 3113, related book 3114, optional input item 3115, checkpoint 3116, and application pattern 3117.

  A check item 3212 indicates the content of the check process. The item number 3211 (an example of order information) specifies the check process indicated by the check item 3212. The item type 3213 indicates the type of result information of the check process indicated by the check item 3212. The related book 3214 indicates the name of a related book related to the check process indicated by the check item 3212. The optional input item 3215 indicates whether the execution of the check process indicated by the check item 3212 is essential or optional.

  A check point 3216 (an example of check point information) indicates a timing condition for performing the check process indicated by the check item 3112. Specifically, in the check process indicated by the check item 3212 of the record in which “1” is set as the check point 3216, a number smaller than the number set as the item number 3211 of this record is set as the item number 3211. This must be done after all of the records that have been checked are complete.

  An application pattern 3217 indicates what kind of model specifications the check processing content indicated by the check item 3112 is applied to.

  The model specification 3218 (an example of model specification information) includes a model identifier for identifying each product belonging to the product group. The model specification 3218 is associated with each element in the two-dimensional matrix defined by the model identifier column and the row including the item number 3211 to the application pattern 3217, and each check item for the product indicated by each model identifier. Whether the check process indicated by 3212 is performed or not is shown. The element for which “1” is set indicates that the check process indicated by the check item 3212 in the row is performed on the product indicated by the model identifier in the column. An element for which “0” is set indicates that the check process indicated by the check item 3212 in the row is not performed on the product indicated by the model identifier in the column.

  The model-specific check item list creation unit 1500 includes, for each model, the model specification data 3010 stored in the model specification information storage unit 3000 and the check item data 3110 stored in the check item information storage unit 3100. As described in <Model-Specific Check Item List Creation Method> of one embodiment, it is determined whether check processing is performed for all “item numbers”, and the model-specific check item list table 3210 is created.

  The difference between the work record collection process of the work record management system 100 of the second embodiment and the work record collection process of the work record management system 100 of the first embodiment is that a check item list is created in step S22 of the flowchart of FIG. Only processing.

  The model-specific item list creation unit 1600 of the first embodiment performs the processing shown in the flowchart of FIG. 11, but the model-specific item list creation unit 1600 of the second embodiment is stored in the model-specific check item list storage unit 3200. A model-specific check item list 3310 (FIG. 6) of a desired model is created from the model-specific check item list table 3210. Specifically, the model-specific item list creation unit 1600 of the second embodiment reads a row in which “1” is set in the element of the column in which the desired model identifier is set as the model specification 3218, and the desired model identifier is generated. The model-specific check item list 3310 is created.

  If the model-specific check item list 3310 is individually created for each model specification 3218, it is necessary to create 27 model-specific check item lists 3310 as shown in FIG. Effort is required. However, in the second embodiment, as shown in FIG. 14, the model-specific check item list table 3210 is created by aggregating information for each product group. As a result, the load for creating the list can be reduced, and the viewability of the created list can be improved.

<Third Embodiment>
The check sheet 20 plays a role of manufacturing performance record and a role of quality record. Therefore, when changing the content of information related to specifications such as model specification data 3010, check item data 3110, model-specific check item list 3310, model-specific check item list table 3210, etc., which are the basis for creating the check sheet 20. Usually, it is necessary to obtain approval from the manufacturing department or the quality assurance department.

  Therefore, if difference information before and after the change of information related to the specification is extracted and clearly indicated, it becomes easy to check the quality of the information related to the changed specification. In the third embodiment, difference information between the model-specific check item list table 3210 before the change and the model-specific check item list table 3210 after the change is extracted.

  FIG. 15 is a diagram illustrating an example of the model-specific check item list table 3210 stored in the model-specific check item list storage unit 3200. FIG. 16 is a diagram illustrating another example of the model-specific check item list table 3210 stored in the model-specific check item list storage unit 3200.

  The model-specific check item list table 3210 (an example of second master information) in FIG. 16 is created by changing a part of the model-specific check item list table 3210 (an example of first master information) in FIG. is there. The model specification 3218 in FIG. 15 is an example of first model specification information. The model specification 3218 in FIG. 16 is an example of second model specification information.

  Items to be changed in the model-specific check item list table 3210 include the contents of the check process indicated by the check item 3212, the item type 3213, the check point 3216, the model identifier included in the model specification 3218, the line of the check item 3212 and the model. A value of an element of a two-dimensional matrix defined by the identifier column can be considered.

  In the third embodiment, the check item 3212 is changed from “3” to “7” in the item number 3211 of “casing serial number confirmation”. The application pattern 3217 in which the check item 3212 is “casing serial number confirmation” is changed from “common” to “domestic”.

  The check point 3216 in which the item number 3211 is “10” and the check item 3212 is “drive unit body assembly confirmation” is changed from “1” to “0”. The related book 3214 in which the item number 3211 is “13” and the check item 3212 is “driving unit main body test run” is changed from “procedure 003” to “procedure 006”. In addition, a special specification “MS03-B3ES” is added to the model specification 3218.

  FIG. 17 is a block diagram illustrating functions of the management server device 1000, the file server device 1800, the production management system 1900, and the work terminal device 2000 according to the third embodiment. As shown in FIG. 17, the configuration of the management server device 1000 of the third embodiment is obtained by adding a master information management unit 1750 to the management server device 1000 of the second embodiment.

  The master information management unit 1750 manages the change contents of the model-specific check item list table 3210 stored in the model-specific check item list storage unit 3200. When the model-specific check item list table 3210 is changed, the master information management unit 1750 extracts difference information of the model-specific check item list table 3210 before and after the change. In the third embodiment, the master information management unit 1750 extracts difference information between the model-specific check item list table 3210 in FIG. 15 and the model-specific check item list table 3210 in FIG.

  FIG. 18 is a flowchart schematically illustrating an example of a procedure for extracting difference information from the model-specific check item list table 3210 before and after the change by the master information management unit 1750.

  First, in step S1801, the master information management unit 1750 acquires the model-specific check item list table 3210 in FIG. 15 and the model-specific check item list table 3210 in FIG. 16 from the model-specific check item list storage unit 3200.

  In step S1802, the master information management unit 1750 extracts check-related information from the acquired model-specific check item list table 3210 in FIG. 15 and the model-specific check item list table 3210 in FIG. Each of the master information management units 1750 adds check group information to the extracted check related information to create check addition information.

  FIG. 19 is a diagram showing additional check information 3230 in which group information 3231 is added to the check related information 3220 extracted from the model-specific check item list table 3210 of FIG. FIG. 20 is a diagram showing additional check information 3230 in which group information 3231 is added to the check related information 3220 extracted from the model-specific check item list table 3210 of FIG.

  As shown in FIGS. 19 and 20, the check related information 3220 includes data from item number 3211 to check point 3216 in the model-specific check item list table 3210. The check related information 3220 in FIG. 19 is an example of first check related information. The check related information 3220 in FIG. 20 is an example of second check related information.

  The group information 3231 is set in order from the item whose item number 3211 is “1”. In the third embodiment, as shown in FIGS. 19 and 20, “P1” is initially set as the value of the group information 3231.

  The master information management unit 1750 is an item whose “checkpoint 3216 is“ 1 ”and has check-related information 3220 excluding the item number 3211 (in the third embodiment, from the check item 3212 to the checkpoint 3216). 5 item) has the same content, if the condition “existing check related information 3220 before and after change (that is, the model-specific check item list table 3210)” is satisfied, the group information 3231 from the next item is satisfied. Change the value of.

  For example, in FIG. 19, the check point 3216 of the check item 3212 “confirmation of drive unit body assembly” is “1”, but in FIG. 20, the check point 3216 of the corresponding check item 3212 of “confirmation of drive unit body assembly” is It is “0”. Therefore, since the condition that “the item whose check point 3216 is“ 1 ”exists in both the model-specific check item list tables 3210 before and after the change” is not satisfied, the value of the group information 3231 does not change, and the group information The value of 3231 remains “P1”.

  In FIG. 19 and FIG. 20, the check item 3212 is an item in which “check point 3216 is“ 1 ”for the item“ drive unit main body final confirmation ”and the check related information 3220 excluding the item number 3211. In the third embodiment, items having the same content (5 items from the check item 3212 to the check point 3216) exist in both the check related information 3220 before and after the change (that is, the model-specific check item list table 3210). Is satisfied. Therefore, the value of the group information 3231 changes from the item whose next item number 3211 is “26”, and “P2” is set as the value of the group information 3231. Note that the checkpoint 3216 having a value “1” is an example of first checkpoint information.

  Note that the value of the group information 3231 may be increased in order using numbers such as “1”, “2”, and “3”. Alternatively, the value of the group information 3231 may be changed in order using symbols such as “A”, “B”, and “C”.

  In the example of FIGS. 19 and 20, the item number 3211 whose check item 3212 is “driving unit body final confirmation” is the check-related information 3220 (FIG. 19) of the model-specific check item list table 3210 before the change. Also in the check related information 3220 (FIG. 20) of the model-specific check item list table 3210, both are “25” and the same. On the other hand, for example, a new item may be added in the model-specific check item list table 3210 after the change, and the item number 3211 of “driving unit main body final confirmation” may be increased from “25”. However, even in this case, the item number 3211 is not used for the determination of “items having the same content”, and thus does not affect the above determination. As a result, as described above, the value of the group information 3231 changes from the next item.

  Here, the group information 3231 will be further described. As described above, the check point 3216 in the model-specific check item list table 3210 indicates whether or not the order in which the check processing is performed needs to be observed. In other words, when “1” is set in the check point 3216, it is prohibited to change the order of execution of the check processing beyond the item “1” when the check point 3216 is performed on the production line. Has been. As described above, in order to restrict the actual work, it is necessary to confirm whether or not the order of execution of the check processing has changed beyond the check point in the model-specific check item list table 3210.

  Therefore, it is considered that “group information” is given to each check item 3212. As a value of this “group information”, for example, “Q1” is first set. If the check point 3216 is set to “0”, the “group information” is set to the same value in the order of the check items 3212. If the check point 3216 is set to “1”, the value of “group information” is changed to “Q2” from the next item, for example. That is, “group information” having the same value is set in a range of check items in which the execution order of check processing is restricted.

  When determining the duplication of contents before and after the change of the model-specific check item list table 3210, if “group information” is taken into consideration, check items that share the same “group information” are checked. Even if the order is changed, it is not recognized as a difference but is determined to be duplicated. However, a change in the order of the check processes in which the values of “group information” are different is recognized as a difference. Thereby, it is possible to confirm the change of the order of the execution of the check processing across the check points.

  Normally, the check process in which the check point 3216 is set to “1” may have a standard content of “** final confirmation of the process” at the end of each process such as the end of the piping process or the end of the trial operation process. Often, the value of checkpoint 3216 does not change frequently. As described above, when the value of the check point 3216 is not changed, the “group information” may be used.

  For example, in FIG. 20, a case where the item number 3211 is “10” and the check point 3216 is “1”, that is, the same case as in FIG. In this case, in the “group information”, in both FIGS. 19 and 20, the item number 3211 is set to “Q1” from “1” to “10”, and from “11” to “25”. Is set to “Q2”, and “26” and thereafter are set to “Q3”.

  However, in rare cases, the value of the check point 3216 may be changed from “0” to “1”, or may be changed from “1” to “0”. In this case, the value of the “group information” is set sequentially shifted from each other in the check additional information 3230 before and after the change.

  For example, in the check additional information 3230 of FIG. 19, the value of the “group information” is set to “Q1” when the item number 3211 is “1” to “10”, and “11” to “25” is “ “Q2” is set, and “26” and thereafter are set to “Q3”.

  On the other hand, for example, in the check additional information 3230 in FIG. 20, the value of the “group information” is set to “Q1” when the item number 3211 is “1” to “25”, and after “26” “Q2” is set.

  Therefore, for example, if the item number 3211 is “14” to “16”, even if there is no change in the content of the check processing indicated in the check item 3212 and the actual order of execution, it is determined that there is no duplication. End up.

  Therefore, in the third embodiment, the value of the group information 3231 is different from the “group information” described above, and as described above, the item “checkpoint 3216 is“ 1 ”and the item number 3211 is set. When the condition that the check related information 3220 excluding the same content exists in both the check related information 3220 before and after the change (that is, the model-specific check item list table 3210) is satisfied, the item of the next item number 3211 is satisfied. Change from.

  With this condition, as shown in FIG. 19, the value of the group information 3231 does not change in the next item whose item number 3211 is “10” in which the check point 3216 is set to “1”, and “P1”. Will remain. As a result, the value of the group information 3231 can be prevented from shifting between the check additional information 3230 before the change in FIG. 19 and the check additional information 3230 after the change in FIG. As a result, the difference before and after the change can be correctly extracted.

  In the third embodiment, the value of the check point 3216 whose item number 3211 is “10” is changed from “1” before the change to “0” after the change. In addition to such a change, for example, a change in which an item in which the checkpoint 3216 is set to “1” is newly added between each item in which the checkpoint 3216 is set to “1”, and the checkpoint 3216 is “ Even in the case of a change to delete an item set to “1”, the above condition is not satisfied, so that the value of the group information 3231 can be prevented from shifting.

  Returning to FIG. 18, in step S1803, master information management section 1750 creates parallel information 3240 by arranging check additional information 3230 (FIG. 19) before the change and check additional information 3230 (FIG. 20) after the change. To do.

  FIG. 21 is a diagram showing the parallel information 3240. In FIG. 21, an item number (old) 3211a represents the item number 3211 of the model-specific check item list table 3210 (FIG. 15) before the change, and an item number (new) 3211b represents the model-type check item list table after the change. The item number 3211 of 3210 (FIG. 16) is represented. As shown in FIG. 21, the parallel information 3240 includes all the information of the check additional information 3230 (FIGS. 19 and 20) in the model-specific check item list table 3210 before and after the change regardless of the overlapping contents. Yes.

  Returning to FIG. 18, in step S1804, the master information management unit 1750 stores items other than the item numbers 3211a and 3211b in the parallel information 3240 (in this third embodiment, six items from the check item 3212 to the group information 3231). Items with overlapping contents are collected in one line, and check integrated information 3250 (FIG. 22) in which only items with different contents are arranged is created.

  The master information management unit 1750 may generally use a hash table implementation implemented in a high-level language such as Ruby or Perl. When hash codes that are characteristic identification information representing the contents of an item are used, the same hash code is assigned if the contents of the items are the same, and different hash codes are assigned if the contents of the items are different. The By using a hash code, the master information management unit 1750 can obtain a list in which overlapping contents are collected into one line and only items having different contents are arranged.

  FIG. 22 is a diagram showing check integrated information 3250 (an example of first integrated information). In the parallel information 3240, when there is an item whose contents of the check additional information 3230 of the model-specific check item list table 3210 before and after the change are duplicated, only one line is shown as the item in FIG. Since the numbers are written in (old) 3211a and item number (new) 3211b, it can be seen that there were items both before and after the change.

  An item whose number is described only in one of the item number (old) 3211a and the item number (new) 3211b is a changed item, an added item, or a deleted item. It is an item that exists only in one of these.

  As described above, in the third embodiment, when the master information management unit 1750 creates the check integration information 3250 from the parallel information 3240, the item number 3211a, 3211b is not used.

  Here, with reference to FIG. 22, the case where the item numbers 3211a and 3211b are used for determining whether or not the contents before and after the change overlap is considered. In this case, it is determined that the item number (old) 3211a is “7” and the item number (new) 3211b is “3”. Similarly. The item number (old) 3211a is “3” and the item number (new) 3211b is “7”. The other items are all the same, but are determined not to overlap.

  Thus, even if all items other than the item numbers 3211a and 3211b are the same, it is determined that they are not duplicated. As a result, the check integration information 3250 becomes complicated. Further, in actual work on the production line, the order of execution of the check processing is not always strictly questioned. Therefore, in the third embodiment, the master information management unit 1750 does not use the item numbers 3211a and 3211b for determining whether or not the contents before and after the change overlap.

  Returning to FIG. 18, in step S1805, the master information management unit 1750, the code information of the model specification 3218 (FIG. 19) of the model check item list table 3210 before the change and the model check item list table 3210 after the change. The model specification code parallel information 3260 is generated by arranging the code information of the model specification 3218 (FIG. 20).

  FIG. 23 is a diagram showing model specification code parallel information 3260. In FIG. 23, the model identifier of the model specification (old) 3218a represents the model identifier of the model specification 3218 of the model-specific check item list table 3210 before the change, and the model identifier of the model specification (new) 3218b represents the model after the change. The model identifier of the model specification 3218 of the separate check item list table 3210 is represented. As shown in FIG. 23, the model specification code parallel information 3260 includes all the model identifiers of the model specifications 3218 (FIGS. 19 and 20) in the model-specific check item list table 3210 before and after the change regardless of the overlapping contents. include.

  Referring back to FIG. 18, in step S1806, the master information management unit 1750 combines the model specification code parallel information 3260 with the same content, and the model specification code integrated information 3270 (only the different content is arranged). FIG. 24) is created.

  FIG. 24 is a diagram showing model specification code integration information 3270 (an example of second integration information). In the third embodiment, the model specification 3218 (FIG. 20) of the model-specific check item list table 3210 after the change is special to the model specification 3218 (FIG. 19) of the model-specific check item list table 3210 before the change. Only the specification “MS03-B3ES” has been added. Accordingly, the model identifier of the model specification (old / new) 3218c of the model specification code integrated information 3270 in FIG. 24 is the same as the model identifier of the model specification 3218 in the model-specific check item list table 3210 after the change shown in FIG. is there.

  In FIG. 18, the master information management unit 1750 may execute steps S1805 to S1806 in parallel with steps S1802 to S1804, may be executed after steps S1802 to S1804, and precedes steps S1802 to S1804. May be executed.

  Next, in step S1807, the master information management unit 1750 first creates a combination table 3280 by combining the check integration information 3250 created in step S1804 and the model specification code integration information 3270 created in step S1806. To do.

  FIG. 25 is a diagram showing the combination table 3280. As shown in FIG. 25, the combination table 3280 is configured by arranging check integrated information 3250 shown in FIG. 22 and model specification code integrated information 3270 shown in FIG. In FIG. 25, each cell in the two-dimensional matrix defined by the model identifier column in the model specification (old / new) 3218c of the combination table 3280 and the row of the check item 3212 is blank.

  Returning to FIG. 18, in step S 1807, the master information management unit 1750 further generates a difference vector. The master information management unit 1750 describes the generated difference vector in each cell of the combination table 3280 that is blank in FIG. The difference vector includes a first element related to the model-specific check item list table 3210 (FIG. 15) before the change and a second element related to the model-specific check item list table 3210 (FIG. 16) after the change.

  FIG. 26 is a diagram showing a combination table 3280 in which difference vectors are described. In FIG. 26, the item type 3213 to the group information 3231 are not shown.

  The first element of the difference vector is the value of the corresponding cell in the model-specific check item list table 3210 (FIG. 15) before the change. The second element of the difference vector is the value of the corresponding cell in the model-specific check item list table 3210 (FIG. 16) after the change. That is, the first element and the second element of the difference vector are set to “1” when the check process indicated by the corresponding check item 3212 is performed on the product indicated by the model identifier of the model specification 3218c. If not implemented, “0” is set. If the corresponding check item 3212 does not exist or has been changed, in the third embodiment, the first element and the second element are set to “2”.

  In FIG. 26, as an example, a cell difference vector defined by the row of “casing serial number confirmation” in the check item 3212 and the column of the model identifier “MS03-A1A” of the model specification (old / new) 3218c is described. Is done.

  In the model-specific check item list table 3210 before change shown in FIG. 15, the check item 3212 is a cell defined by a row of “casing serial No. confirmation” and a column of the model identifier “MS03-A1A” of the model specification 3218. Is set to “1”. Therefore, the first element of the difference vector is “1”.

  In the model-specific check item list table 3210 after the change shown in FIG. 16, the cell specified by the check item 3212 is a row of “casing serial No. confirmation” and a column of the model identifier “MS03-A1A” of the model specification 3218. Is set to “0”. Therefore, the second element of the difference vector is “0”.

  Therefore, as shown in FIG. 26, the difference between the cells specified by the check item 3212 in the row of “casing serial No. confirmation” and the column of the model identifier “MS03-A1A” of the model specification (old / new) 3218c. The vector becomes [1, 0].

  In FIG. 26, as another example, the cell difference vector defined by the row of the item number (old) 3211a “10” and the column of the model identifier “MS03-A1J” of the model specification (old / new) 3218c is shown. Explained.

  In the model-specific check item list table 3210 before the change shown in FIG. 15, the cell defined by the row of the item number 3211 “10” and the column of the model identifier “MS03-A1J” of the model specification 3218 is “1 "Is set. Therefore, the first element of the difference vector is “1”.

  On the other hand, in the combination table 3280 of FIG. 26, there is a row where the item number (new) 3211b is “10”. As a result, the changed model-specific check item list table 3210 indicates that there is no row having the item number (old) 3211a of “10”. For this reason, the second element of the difference vector is “2”.

  Therefore, as shown in FIG. 26, the cell difference vector defined by the row of the item number (old) 3211a of “10” and the column of the model identifier “MS03-A1J” of the model specification (old / new) 3218c. Becomes [1,2].

  Returning to FIG. 18, in step S1808, the master information management unit 1750 converts the difference vectors described in the combination table 3280 (FIG. 26) into converted values using the difference vector conversion table 3285 (FIG. 27). The master information management unit 1750 creates a difference check table 3290 (FIG. 28) in which the conversion value is described instead of the difference vector, and ends the process of FIG.

  FIG. 27 is a diagram showing the difference vector conversion table 3285. FIG. 28 is a diagram showing a difference check table 3290 (an example of difference information).

  When the first element of the difference vector is “0” or “2” and the second element is “0” or “2”, the corresponding check process is not performed before or after the change, or the corresponding check process is performed. It means not existing. Therefore, the difference vectors [0, 0], [0, 2], [2, 0], [2, 2] are converted into a conversion value “0” as shown in FIG.

  When the first element of the difference vector is “1” and the second element is “1”, it means that corresponding check processing is performed before and after the change. Therefore, the difference vector [1, 1] is converted into a conversion value “1” as shown in FIG.

  When the first element of the difference vector is “0” or “2” and the second element is “1”, check processing that was not performed before the change or did not exist before the change This means that the check process is performed after the change. Therefore, the difference vectors [0, 1] and [2, 1] are converted into a conversion value “A” as shown in FIG. For example, in FIG. 28, each cell in the row whose item number (new) 3211b is “10”. The value “A” is adopted from the first character of ADD meaning addition.

  If the first element of the difference vector is “1” and the second element is “0” or “2”, the check processing that was performed before the change is no longer performed after the change or This means that there is no check processing to be performed. Therefore, the difference vectors [1, 0] and [1, 2] are converted into a conversion value “D” as shown in FIG. For example, in FIG. 28, the item number (old) 3211a excluding the column of the model identifier “MS03-B3ES” is the row “10”. The value “D” is adopted from the first character of DELETE indicating deletion.

  In the difference check table 3290 illustrated in FIG. 28, when a check process that has not been performed is newly performed, the conversion value “A” is displayed, and the check process that has been performed is not newly performed. Displays the conversion value “D”.

  As described above, in the third embodiment, the difference vector is not converted into a character but is converted into a character, and the difference is represented by the character. Therefore, the person in charge of the manufacturing department or the quality assurance department can easily find the changed part of the machine type check item list table 3210 (FIG. 16) after the change with respect to the machine type check item list table 3210 (FIG. 15) before the change. I can understand.
