Description

  The present invention relates to a parts table management apparatus, a parts table management method, and a program for managing a parts table related to product design and production.

  2. Description of the Related Art Conventionally, information systems that use information processing technology to improve the efficiency of various operations in corporate activities are known. The information system introduced in the manufacturing industry uses information on the bill of materials (BOM) related to product design and production as a master in order to improve operational efficiency such as product design, parts procurement, and production. There are many things to keep. The parts table is a list of each part constituting the product. For example, there is a part list including a minimum unit part, a subordinate component, an intermediate product, and the like, and the relationship between each element is expressed in a hierarchical structure.

  The parts table has a different structure depending on the application. The bill of materials used in the design stage is called a design bill of materials (E-BOM: Engineering BOM), and has a functional unit hierarchical structure in which the elements constituting the bill of material are grouped in units of product functions. On the other hand, the bill of materials used in the production stage is called a production bill of materials (M-BOM: Manufacturing BOM). The parts are replaced with actual purchased parts. The production parts table is generally constructed based on the design parts table. That is, the production parts table is first constructed by copying the design parts table and then recombining the hierarchical structure taking into account the product assembly process and actual purchased parts.

  When a change occurs in the design bill of materials due to a product design change or the like, it is necessary to reflect the change in the design bill of materials in the production bill of materials. Many of the existing information systems change the production parts table according to the change of the design parts table by a manual operation. That is, a person determines where the change in the design bill of materials should be reflected in the production bill of materials, and manually performs the work of reflecting the change. For this reason, there has been a problem that an operation error occurs in which a change in the design parts table is not correctly reflected in the production parts table, and a problem that it takes time to reflect the change in the design parts table in the production parts table.

  For such problems, Patent Document 1 retains BOM correspondence data indicating the correspondence between the design BOM and the production BOM, and when changing the BOM, the BOM correspondence A technique is described in which a corresponding production parts table is called using data and displayed side by side with the design parts table, and a corresponding part of the production parts table is changed in accordance with a change operation of the design parts table.

  However, in the technique described in Patent Document 1, in order to specify which part of the production BOM should be changed in accordance with the change of the design BOM, the correspondence between the design BOM and the production BOM is set for each part. There is a problem that it is necessary to generate in advance the parts table correspondence data to be shown, and the work of generating the parts table correspondence data is complicated. In addition, when there is a change in the production bill of materials, it is necessary to change not only the design bill of materials but also the bill of material correspondence data, and always keep the latest bill of material correspondence data. There is a problem that the management of the parts table correspondence data becomes complicated.

  The present invention has been made in view of the above, and a parts table management apparatus, a parts table management method, and a program capable of reflecting a change made in a design parts table in a production parts table while eliminating a complicated operation. The purpose is to provide.

  Exemplary embodiments of a parts table management apparatus, a parts table management method, and a program according to the present invention will be explained below in detail with reference to the accompanying drawings.

(Information system)
First, an overview of an information system including a parts table management apparatus according to an embodiment will be described. FIG. 1 is a configuration diagram of an information system including a parts table management apparatus according to an embodiment. As shown in FIG. 1, this information system includes a parts table management apparatus 1 that manages a design parts table and a production parts table, and a plurality of user terminals 2-1, 2-2,. , Generically referred to as “user terminal 2”) via a communication network 3. The form of the communication network 3 is arbitrary. For example, a LAN (Local Area Network) in a company where an information system is introduced or a WAN (Wide Area Network) in which a plurality of LANs are connected by a dedicated line can be used. .

  The BOM management device 1 has a hardware configuration, for example, a control device such as a CPU, an internal storage device such as a ROM or a RAM, an external storage device such as a hard disk, CD, DVD, or flash memory, and communication using a communication network 3. It is possible to employ a hardware configuration using a computer that includes a communication device for performing the above. In this case, when the computer executes the program, a functional configuration described later in the BOM management apparatus 1 is realized. For example, display information of the design BOM and the production BOM is generated, and a change request for the design BOM is requested. Various processes such as reception, change of the design parts list, and reflection of the change of the design parts list to the production parts list are executed.

  The user terminal 2 is a terminal used by a user such as a designer in charge of using a design parts list or a person in charge of production using a production parts list. As the user terminal 2, for example, a personal computer, a PDA, a tablet terminal, or the like, an input device for a user to perform various input operations, a display device for displaying various information, and communication using the communication network 3 are performed. A terminal equipped with a communication device as hardware can be used.

  In the information system of FIG. 1, when a person in charge of design accesses the BOM management device 1 using the user terminal 2 and requests to view a desired design BOM, display information of the design BOM is displayed in the BOM management device 1. It is generated and sent to the user terminal 2, and the design parts table is displayed on the user terminal 2. Further, when the person in charge of production accesses the BOM management device 1 using the user terminal 2 and requests browsing of a desired production BOM, display information of the production BOM is generated in the BOM management device 1 and the user terminal 2 and the production parts table is displayed on the user terminal 2. When the person in charge of the design accesses the BOM management device 1 using the user terminal 2 and makes a change request to change the desired design BOM, the design corresponding to the change request is made in the BOM management device 1. The bill of materials is changed and reflected in the production bill of materials.

(Parts list)
FIG. 2 is a schematic diagram conceptually showing the relationship between the design parts table and the production parts table. The design bill of materials is a bill of materials used in the product design stage, and has a functional unit hierarchical structure in which the elements constituting the bill of material are grouped in units of product functions. In the design parts table illustrated in FIG. 2, there are “functional element 1” and “functional element 2” as child elements of “product” which is a root element, and “part A” and “functional element 1” are child elements of “functional element 1”. This indicates that “part C” is present, “part B” is a child element of “part A”, and “part D” is a child element of “functional element 2”.

  On the other hand, the production bill of materials is a bill of materials used in the product production stage, and has a unit-unit hierarchical structure in which each element constituting the bill of materials is grouped in units of product assembly units. Replaced with purchased parts. The production parts table is constructed by copying the design parts table and then rearranging the hierarchical structure in consideration of the product assembly process and actual purchased parts. In the production parts table illustrated in FIG. 2, “unit 1” and “unit 2” are child elements of “product” that is a root element, and “part A” is a child element of “unit 1”. It shows that “part B ′” is a child element of “A”, and “part C” and “part D” are child elements of “unit 2”. “Unit 1” is an element converted from “functional element 1” in the design parts table in consideration of the product assembly process, and “Unit 2” is “element 1” in the design part list in consideration of the product assembly process. This is an element converted from “Function element 2”. In addition, “component C” has “functional element 1” and “functional element 2” in the design parts table converted into “unit 1” and “unit 2” in accordance with the conversion of “functional element 1” and “functional element 2”. "Is a child element of" Unit 2 ". “Part B ′” is the same part as “Part B” in the design parts table, but is replaced from “Part B” as an actual purchased part by changing the supplier or the like.

  FIG. 3 is a schematic diagram conceptually showing how changes to the design parts table are reflected in the production parts table. When a change occurs in the design bill of materials due to a product design change or the like, it is necessary to reflect the change in the design bill of materials in the production bill of materials. FIG. 3 shows how changes to the design parts table illustrated in FIG. 2 are reflected in the production parts table.

  Specifically, when there is a change to update “part B” to a new version on the design parts table, “part B ′” replaced from “part B” is the same on the production parts table. Make changes to update to a new version. Each element of the design parts table and the production parts table is given a part number as identification information and managed by this part number. Elements having the same part number are the same. However, the improvement (version upgrade) of an element is managed by the suffix attached to the part number, and the update to update the part table element to a new version changes the suffix of the part number that is the identification information of the element. It means to do. Hereinafter, such a change that updates the elements of the design parts table and the production parts table to a new version is referred to as a suffix change.

  Further, when there is a change to add “part E” as a child element of “part A” to the design parts list, “part E” as a child element of “part A” is similarly applied to the production parts list. To make changes. Further, when there is a change to add “part F” as a child element of “functional element 2” to the design parts table, “unit 2” converted from “functional element 2” to the production parts table Change to add “part F” as a child element of Although not shown in FIG. 3, when there is a change to delete any element in the design BOM, the same element as the element deleted in the design BOM is deleted from the production BOM. Make a change.

  Such a change in the production bill of materials accompanying a change in the design bill of materials may cause a problem such as an error in that the change of the design bill of materials is not correctly reflected in the production bill of materials when the manual work is performed. There is a problem that it takes time to reflect the change in the production parts table. In addition, as disclosed in Patent Document 1, the part correspondence data indicating the correspondence between each element of the design parts table and each element of the production parts table is held, and the design parts table is changed. In this case, there is a method of changing the production parts table using the correspondence data. However, in this method, the work of generating the parts table correspondence data is complicated, and the management thereof is also complicated.

  Therefore, the BOM management apparatus 1 according to the embodiment has the following configuration, and does not require a complicated operation such as generating and managing data indicating the correspondence relationship between the design BOM and the production BOM in advance. Can be reflected in the production bill of materials.

(Parts table management device)
FIG. 4 is a configuration diagram of the parts table management apparatus 1. As shown in FIG. 4, the BOM management device 1 includes a storage device 10, a storage control device 20, a communication device 30, and a data processing device 40.

  The storage device 10 includes a first component information storage unit 11, a first configuration information storage unit 12, a second component information storage unit 13, a second configuration information storage unit 14, and a change information storage unit 15. . In FIG. 4, the first component information storage unit 11, the first configuration information storage unit 12, the second component information storage unit 13, the second configuration information storage unit 14, and the change information storage unit 15 are included in one storage device. However, as actual hardware, a plurality of storage devices may be used and the above-described units may be distributed and realized.

  The first part information storage unit 11 stores first part information including a part number (identification information) of each element of the design parts table. FIG. 5 is a diagram illustrating an example of a data format of the first component information. The first part information has information on a combination of a part number and attribute information as shown in FIG. 5 for each element of the design parts table. The part number is identification information for uniquely identifying a target element (including not only a final unit part but also a part or a functional element configured by combining a plurality of parts). The attribute information is information representing the attribute of the target element, and is, for example, the size and name of the target element. The first part information storage unit 11 includes, for example, “functional element 1”, “functional element 2”, “part A”, “part B”, “part B” as first part information corresponding to the design part table illustrated in FIG. Information of combinations of part numbers and attribute information of “part C” and “part D” is stored.

  The first configuration information storage unit 12 stores first configuration information indicating a parent-child relationship between elements in the hierarchical structure of the design parts table. FIG. 6 is a diagram illustrating an example of a data format of the first configuration information. For example, as shown in FIG. 6, the first configuration information is a parent element number (parent element number) and a child of all parent-child relationships between elements in the hierarchical structure of the design parts table. It has information combining the part number (child part number) of the element (child element) and the number (number) of child elements with respect to the parent element. The first configuration information storage unit 12 includes, for example, information indicating a parent-child relationship between “functional element 1” and “part A” as first configuration information corresponding to the design parts table illustrated in FIG. "Indicating the parent-child relationship between" component C ", information indicating the parent-child relationship between" functional element 2 "and" component D ", and information indicating the parent-child relationship between" component A "and" component B " Is remembered.

  The second part information storage unit 13 stores second part information including the part number (identification information) of each element of the production parts table. The data format of the second component information is the same as the data format of the first component information shown in FIG. However, in the second part information, among the elements that make up the production parts table, the elements that are replaced from the elements in the design parts table, that is, the elements that are replaced with the actual purchased parts by changing the supplier, etc. The attribute information includes the part number of the element before replacement. In other words, for the element replaced from the element in the design parts table, the part number of the element before replacement (the same element as in the design parts table) can be specified by checking the attribute information. The second part information storage unit 13 includes, for example, “unit 1”, “unit 2”, “part A”, “part B ′”, “part” as second part information corresponding to the production parts table illustrated in FIG. Information of combinations of part numbers and attribute information of “C” and “part D” is stored. Among these, the attribute information of “component B ′” includes a part number of “component B” which is an element before replacement.

  The second configuration information storage unit 14 stores second configuration information indicating a parent-child relationship between elements in the hierarchical structure of the production parts table. The data format of the second configuration information is the same as the data format of the first configuration information shown in FIG. For example, as the second configuration information corresponding to the production parts table illustrated in FIG. 2, the second configuration information storage unit 14 includes information indicating a parent-child relationship between “unit 1” and “part A”, “unit 2”, Information indicating a parent-child relationship with “component C”, information indicating a parent-child relationship between “unit 2” and “component D”, and information indicating a parent-child relationship between “component A” and “component B ′” I remember it.

  When the receiving unit 43 of the data processing device 40 described later receives a change request for the design parts table, the change information storage unit 15 changes the change contents of the design parts table based on the change request, that is, the design parts table. The change information representing the change contents of the first component information and the first configuration information necessary for this is stored.

  The storage control device 20 controls writing, deleting, and reading of information with respect to the storage device 10. Specifically, the storage control device 20 writes information to be written into a specified area of the storage device 10 in response to a write request from the data processing device 40. Further, the storage control device 20 deletes information to be deleted from a specified area of the storage area 10 in response to a deletion request from the data processing apparatus 40. Further, in response to a read request from the data processing device 40, the storage control device 20 reads information to be read from a specified area of the storage device 10 and transfers it to the data processing device 40.

  The communication device 30 performs communication with the user terminal 2 using the communication network 3. A request for browsing the design parts table and the production parts table transmitted from the user terminal 2 via the communication network 3, a request for changing the design parts table, and the like are received by the communication device 30 and transmitted to the data processing device 40. In addition, the display information of the design parts table and the production parts table generated by the data processing device 40 in response to the browsing request from the user terminal 2 is transmitted from the communication device 30 via the communication network 3 to the user terminal 2 that has transmitted the browsing request. Sent to.

  The data processing device 40 executes various types of data processing. As a functional configuration, the data processing device 40 includes a design parts table generation unit 41, a production parts table generation unit 42, a reception unit 43, a first change unit 44, and a determination unit 45. And a second changing unit 46. As described above, when a computer is used as the BOM management device 1, these functional configurations can be realized by a program executed by the computer. In addition, a part or all of the above functional configuration can be realized by using dedicated hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

  The design parts table generation unit 41 stores the first part information stored in the first part information storage unit 11 of the storage device 10 and the first configuration information storage unit 12 when there is a browsing request for the design parts table. Based on the stored first configuration information, display information of the designated design parts table is generated. The display information of the design parts table generated by the design parts table generation unit 41 is transmitted from the communication device 30 via the communication network 3 to the user terminal 2 that transmitted the browsing request. As a result, the designated design parts table is displayed on the user terminal 2 that has transmitted the browsing request.

  The production parts table generation unit 42 stores the second parts information stored in the second parts information storage unit 13 of the storage device 10 and the second configuration information storage unit 14 when there is a browsing request for the production parts table. Based on the stored second configuration information, display information of the designated production parts table is generated. The display information of the production parts table generated by the production parts table generator 42 is transmitted from the communication device 30 to the user terminal 2 that has transmitted the browsing request via the communication network 3. As a result, the designated production parts table is displayed on the user terminal 2 that has transmitted the browsing request.

  The receiving unit 43 receives a change request for the design parts table. When the person in charge of design makes a change to the design parts table due to a design change or the like, the person in charge of designing first uses the user terminal 2 to make a request for browsing the design parts table to be changed. As a result, the design parts table to be changed is displayed on the user terminal 2. After that, the person in charge of the design performs an operation of changing a necessary part on the design parts table displayed on the user terminal 2. As a result, a change request for the design parts table is transmitted from the user terminal 2 to the parts table management apparatus 1. The accepting unit 43 accepts a change request for the design parts table from the user terminal 2. The change information indicating the change contents of the design parts table based on the change request received by the receiving unit 43 is stored in the change information storage unit 15 of the storage device 10 described above.

  The first change unit 44 is configured to store the first component information stored in the first component information storage unit 11 of the storage device 10 and the first configuration information storage unit 12 based on the change request for the design parts table received by the reception unit 43. Is changed at least one of the first configuration information stored therein. For example, as illustrated in FIG. 3, when there is a change request for adding a suffix change to “part B” in the design parts table, the first change unit 44 sets the “part B” part of the first part information. Change the suffix of the number. When there is a change request for adding “part E” as a child element of “part A” in the design parts table, the first changing unit 44 sets the part number and attribute information of “part E” as the first part information. In addition, information indicating the parent-child relationship between “part A” and “part E” is added to the first configuration information. Note that if the part number and attribute information of “part E” are already included in the first part information, the first configuration information is not changed. Also, if information indicating the parent-child relationship between “part A” and “part E” is already included in the first configuration information, the number of child elements relative to the parent element is increased by one for that information. Add. Although not shown in FIG. 3, when there is a change to delete any element in the design parts table, the first change unit 44 sets the part number and attribute information of the element to be deleted as the first part information. And the information having the element to be deleted as a child element is deleted from the first configuration information.

  In the present embodiment, the process of changing the first part information and the second part information based on the change request is not at the time when the change request is made, for example, to the change of the design parts table requested by the designer. It is also assumed that it will be implemented at the stage of approval by an approver having authority. Therefore, the storage device 10 stores the change information indicating the change contents of the design parts table based on the change request, that is, the change information indicating the change contents that the first change unit 44 performs on the first part information and the second part information. The change information storage unit 15 temporarily stores the change information. In this case, the change information temporarily stored in the change information storage unit 15 is read with the input of the approval by the approver as a trigger. Then, the first changing unit 44 performs processing for changing the first component information and the second component information based on the change information read from the change information storage unit 15.

  The determination unit 45 includes change information stored in the change information storage unit 15 of the storage device 10, second component information stored in the second component information storage unit 13, and second configuration stored in the second configuration information storage unit 14. Based on the information, the contents of the change to the production BOM necessary for reflecting the change to the design BOM are determined. When there is a change to the design BOM, such as an element suffix change, addition, deletion, etc., in order to reflect the change to the design BOM in the production BOM, how and where to change the production BOM It is necessary to decide what to change. The determination unit 45 changes information indicating what kind of change has been made to the design parts table in order to determine the change contents of the production parts table, and second part information for generating the production parts table And the second configuration information. Details of a specific example of processing by the determination unit 45 will be described later.

  The second change unit 46 stores the second part information stored in the second part information storage unit 13 of the storage device 10 and the second configuration information storage unit 14 based on the change content determined by the determination unit 45. 2. At least one of the configuration information is changed. For example, as illustrated in FIG. 3, in order to reflect the suffix change for “part B” in the design BOM in the production BOM, the suffix change for “part B ′” in the production BOM is changed to the production BOM. When the determining unit 45 determines the content, the second changing unit 46 changes the suffix of the part number “component B ′” of the second component information. In addition, "Part E" is added as a child element of "Part A" in the production BOM to reflect the change to add "Part E" as a child element of "Part A" in the design BOM. When the determination unit 45 determines the change to be made as the change content for the production parts table, the second change unit 46 adds the part number and attribute information of “part E” to the second part information, and “part A” Information indicating the parent-child relationship with “part E” is added to the second configuration information. If the part number and attribute information of “component E” are already included in the second component information, the second configuration information is not changed. In addition, if information indicating the parent-child relationship between “part A” and “part E” is already included in the second configuration information, the number of child elements relative to the parent element is increased by one for the information. Add. In addition, when the change content to the production parts table is deletion of any element, the second change unit 46 deletes the part number and attribute information of the element to be deleted from the second part information and also deletes the element to be deleted. Information having the element as a child element is deleted from the second configuration information.

(Processing by the decision unit)
Next, the details of the processing by the determination unit 45 will be specifically described by dividing the case where the change to the design parts table is an addition of an element and the case where the element is a suffix change (update) or deletion.

<Adding elements>
When the change to the design parts table is an addition of elements, the determination unit 45 determines the change contents to the production parts table according to the following rules (1) to (3).
(1) If the same element as the parent element of the element added in the design BOM is included in the production BOM, the same element as the element added in the design BOM is used as the child element of the element. Add to
(2) The same element as the parent element of the element added in the design BOM is not included in the production BOM, and the sibling element of the element added in the design BOM (other child elements having a common parent element) If the same element as) is included in the production BOM, the same element as the element added in the design BOM is added to the production BOM as a sibling element of that element, that is, a child element of the parent element of the element To do.
(3) If neither the same element as the parent element of the element added in the design BOM nor the same element as the sibling element is included in the production BOM, the design part is used as a child element of a predetermined parent element in the production BOM. Add the same element as the element added in the table to the production BOM.

  FIG. 7 is a schematic diagram conceptually showing how the determination unit 45 determines the change contents for the production parts table when the changes to the design parts table are additions of elements. FIG. 7 shows the case where there is a change to add “part E” as a child element of “part A” to the design part table illustrated in FIG. In this example, there is a change in which “component F” is added as a child element of “”.

  When there is a change to add “part E” as a child element of “part A” to the design parts table, the determination unit 45 adds the design information to the design parts table based on the change information stored in the change information storage unit 15. On the other hand, “part A” which is a parent element of “part E” added is specified. Then, the determination unit 45 determines whether or not “part A” is included in the production parts table based on the second part information stored in the second part information storage unit 13. In the example of FIG. 7, since “part A” is included in the production parts table, “part A” is detected. In this case, the determination unit 45 determines a change to add “part E” as a child element of “part A” detected from the production parts table as a change content to the production parts table (the above rule (1)). .

  When there is a change to add “part F” as a child element of “functional element 2” to the design parts table, the determination unit 45 determines the design parts table based on the change information stored in the change information storage unit 15. The “functional element 2” that is the parent element of the “component F” added to is specified. Then, the determination unit 45 determines whether or not “functional element 2” is included in the production parts table based on the second part information stored in the second part information storage unit 13. In the example of FIG. 7, since “functional element 2” is not included in the production parts table, “functional element 2” is not detected. In this case, the determination unit 45 further specifies “part D” which is a sibling element of “part F” added to the second design parts table. Then, the determination unit 45 determines whether or not “part D” is included in the production parts table based on the second part information stored in the second part information storage unit 13. In the example of FIG. 7, since “part D” is included in the production parts table, “part D” is detected. In this case, the determination unit 45 further identifies “unit 2” that is a parent element of “part D” in the production parts table, based on the second configuration information stored in the second configuration information storage unit 14, A change to add “part F” as a child element of “unit 2” is determined as a change content to the production parts table (the above rule (2)).

  Although not shown in the example of FIG. 7, the same element as the parent element of the element added in the design parts table and the same element as the sibling element may not be detected from the production parts table. Even in such a case, the addition of elements to the design parts table needs to be reflected in the production parts table. Therefore, when neither the same element as the parent element of the element added in the design BOM nor the same element as the sibling element is detected from the production BOM, the determination unit 45 selects the same element as the element added in the design BOM. Then, a change to be added to the design BOM as a child element of a predetermined parent element in the design BOM (for example, unit 1 in the production BOM illustrated in FIG. 7) is determined as a change content to the production BOM (above-mentioned Rule (3)).

  FIG. 8 is a flowchart illustrating a procedure of processing in which the determination unit 45 determines the content of change to the production parts table when the change to the design parts table is addition of an element. When there is a change to the design parts table, the determination unit 45 first refers to the change information and confirms the contents of the change to the design parts table. If the change to the design parts table is an addition of an element, the change contents to the production parts table are determined according to the procedure shown in the flowchart of FIG.

  When the change to the design bill of material is an addition of an element, the determination unit 45 first acquires the element added in the design bill of material and the part number of the parent element and sibling element of the element from the change information (step S101). . Then, the determination unit 45 refers to the second part information and determines whether or not the second part information includes the same part number as that of the acquired parent element, that is, the element added in the design parts table. It is determined whether the same element as the parent element is detected from the production parts table (step S102). Here, when the same element as the parent element of the element added in the design BOM is detected from the production BOM (step S102: Yes), the determination unit 45 uses the design as a child element of the detected parent element. A change to add the same element as the element added to the parts table to the production parts table is determined as a change content to the production parts table (step S103).

  On the other hand, when the same element as the parent element of the element added in the design BOM is not detected from the production BOM (step S102: No), the determination unit 45 further refers to the second part information and acquires the sibling element It is determined whether or not the same part number as the part number is included in the second part information, that is, whether or not the same element as the sibling element of the element added in the design parts table is detected from the production parts table (Step S104). Here, when the same element as the sibling element of the element added in the design BOM is detected from the production BOM (step S104: Yes), the determination unit 45 determines the child element of the parent element of the detected sibling element. Then, a change to add the same element as the element added to the design parts table to the production parts table is determined as a change content to the production parts table (step S105).

  On the other hand, when the same element as the sibling element of the element added in the design parts table is not detected from the production parts table (step S104: No), the determination unit 45 uses the design part as a child element of a predetermined element. A change for adding the same element as the element added to the table to the production parts table is determined as a change content to the production parts table (step S106).

  When the determination unit 45 determines the change content for the production parts table as described above, the second change unit 46 changes the second part information and the second configuration information based on the change content determined by the determination unit 45. To do. For example, the change determined by the determination unit 45 is a change in which the same element as the element added to the design BOM is added to the production BOM as a child element of the same element as the parent element of the element added to the design BOM If so (step S103 above), the second changing unit 46 adds the part number and attribute information of the same element as the element added to the design parts table to the second part information and adds it to the design parts table. Information indicating a parent-child relationship in which the same element as the parent element of the selected element is a parent element and the same element as the element added to the design parts table is a child element is added to the second configuration information. Also, the change determined by the determination unit 45 is a change in which the same element as the element added to the design BOM is added to the production BOM as a sibling element of the same element as the sibling element of the element added to the design BOM If so (step S105 described above), the second changing unit 46 adds the part number and attribute information of the same element as the element added to the design parts table to the second part information and adds it to the design parts table. Information indicating a parent-child relationship in which the parent element of the same element as the sibling element of the selected element is a parent element and the same element as the element added to the design parts table is a child element is added to the second configuration information. If the change content determined by the determination unit 45 is a change in which the same element as the element added to the design parts table is added to the production parts table as a child element of the predetermined element (step S106 above), the second The change unit 46 adds the part number and attribute information of the same element as the element added to the design BOM to the second part information, and adds the predetermined element of the design BOM as a parent element and adds it to the design BOM. Information indicating a parent-child relationship with the same element as the child element as a child element is added to the second configuration information.

  When the second part information and the second configuration information are changed by the second changing unit 46, the change to the design parts table is reflected when a production person inspects the production parts table. Display information of the production part information is generated by the production part table generation unit 42 and displayed on the user terminal 2. However, the change contents for the production parts table determined by the determination unit 45 when the design parts table is changed are predictions for automatically reflecting the changes to the design parts table in the production parts table. For this reason, it is desirable that the person in charge of production can confirm where and how the production parts table is changed in accordance with the change of the design parts table while looking at the production parts table. For example, where in the production BOM has been changed due to a change in the display form, such as highlighting a part that reflects changes to the design BOM, or making the display color different from other parts Can be confirmed by the person in charge of production. When the person in charge of production confirms the change of the production parts table and performs a predetermined operation, the change of the display form may be terminated.

<Change or delete element suffix>
When the change to the design BOM is an element suffix change or deletion, the determination unit 45 determines the change contents to the production BOM according to the following rules (1) and (2).
(1) If the same element as the element whose suffix has been changed or deleted is included in the production BOM, the suffix of the element is changed or the element is deleted from the production BOM.
(2) If the same element as the element whose suffix is changed or deleted in the design BOM is not included in the production BOM, the element replaced from the element whose suffix is changed or deleted in the design BOM is detected, and the element is detected. Change the suffix or delete the element from the production bill of materials.

  FIG. 9 is a schematic diagram conceptually showing how the determination unit 45 determines the change contents for the production parts table when the change to the design parts table is an element suffix change. 9 is similar to the example of FIG. 3 in addition to the case where the suffix is changed for “part B” and the suffix is changed for “part D” in the design parts table illustrated in FIG. An example of when there is. It should be noted that if an element is deleted from the design parts table, it can be handled in the same manner as when the suffix is changed, and thus illustration is omitted.

  When the suffix of “part D” is changed in the design parts table, the determination unit 45 identifies “part D” whose suffix has been changed based on the change information stored in the change information storage unit 15. Then, the determination unit 45 determines whether or not “part D” is included in the production parts table based on the second part information stored in the second part information storage unit 13. In the example of FIG. 9, since “part D” is included in the production parts table, “part D” is detected. In this case, the determination unit 45 determines to change the suffix of the “part D” detected from the production parts table in the same manner as the design parts table as a change content to the production parts table (the above rule (1)). .

  When the suffix of “part B” is changed in the design parts table, the determination unit 45 identifies “part B” whose suffix has been changed based on the change information stored in the change information storage unit 15. Then, the determination unit 45 determines whether or not “part B” is included in the production parts table based on the second part information stored in the second part information storage unit 13. In the example of FIG. 9, since “part B” is not included in the production parts table, “part B” is not detected. In this case, the determination unit 45 further refers to the attribute information of the second part information to search for an element whose element before replacement is “part B”, and “part whose element before replacement is“ part B ”. B ′ ”is detected. Then, the determination unit 45 determines to change the suffix of the “part B ′” detected from the production parts table in the same manner as the “part B” in the design parts table as a change content to the production parts table (above-mentioned Rule (2)).

  FIG. 10 is a flowchart showing a procedure of processing in which the determination unit 45 determines the content of change to the production parts table when the change to the design parts table is an element suffix change or deletion. When there is a change to the design parts table, the determination unit 45 first refers to the change information and confirms the contents of the change to the design parts table. If the change to the design parts table is an element suffix change or deletion, the contents to be changed to the production parts table are determined according to the procedure shown in the flowchart of FIG.

  When the change to the design parts table is an element suffix change or deletion, the determination unit 45 first acquires the part number of the element whose suffix is changed or deleted from the design part table from the change information (step S201). Then, the determination unit 45 refers to the second part information and determines whether or not the same part number as the acquired part number is included in the second part information, that is, the element whose suffix is changed or deleted in the design parts table. It is determined whether or not the same element is detected from the production parts table (step S202). Here, when the same element as the element whose suffix is changed or deleted in the design parts table is detected from the production parts table (step S202: Yes), the determination unit 45 detects the detected elements in the same manner as the design parts table. Is changed as a change to the production parts table (step S203).

  On the other hand, when the same element as the element whose suffix is changed or deleted in the design parts table is not detected from the production parts table (step S202: No), the determination unit 45 further refers to the attribute information of the second part information and acquires it. The element having the same part number as the part number of the element before replacement is detected. And the determination part 45 determines the change which changes the suffix of the detected element, or deletes the detected element from a production parts table like the design parts table as a change content with respect to a production parts table (step). S204).

  When the determination unit 45 determines the change content for the production parts table as described above, the second change unit 46 changes the second part information and the second configuration information based on the change content determined by the determination unit 45. To do. That is, if the change content determined by the determination unit 45 is a suffix change for an element of the production parts table, the second change unit 46 changes the suffix of the part number of the corresponding element included in the second part information. If the change content determined by the determination unit 45 is deletion of an element from the production parts table, the second change unit 46 deletes the part number and attribute information of the corresponding element included in the second part information. .

  As described above in detail with specific examples, according to the BOM management apparatus 1 of the present embodiment, when there is a change request for the design BOM from the designer, the receiving unit 43 receives the change request. The first changing unit 44 changes the first part information and the first configuration information for generating the design parts table based on the change request received by the receiving unit 43. In addition, the determination unit 45 changes the design part table to the production part table based on the change information indicating the change contents for the design part table and the second part information and the second configuration information for generating the production part table. Determine the changes to the production bill of materials necessary to reflect them. And the 2nd change part 46 changes the 2nd components information and 2nd structure information for producing | generating a production parts table | surface based on the change content which the determination part 45 determined. As described above, according to the BOM management apparatus 1 of the present embodiment, when a change is made to the design BOM, the change information indicating the change contents to the design BOM and the production BOM are generated. Based on the second part information and the second configuration information, the contents to be changed to the production parts table are automatically determined and the production parts table is changed. For example, the correspondence between the design parts table and the production parts table is shown. Changes that occur in the design parts table can be reflected in the production parts table while eliminating the need for complicated operations such as generating and managing data in advance.
