Description

  In particular, the present invention relates to a schedule management apparatus, a management method and management program for production management of parts and the like, and a schedule management system including the same.

Conventionally, the production schedule planning work for determining the production volume, production time, production order, etc. of products and parts in production management needs to be set and optimized in consideration of cost, delivery date, and the like. In order to display the planned production schedule, the work content is arranged on the vertical axis, the time axis is arranged on the horizontal axis, and the progress between the work is visually displayed as a bar chart with the time axis. The table format etc. which show the information of a track record etc. are used.
For example, in the following Patent Document 1, the horizontal axis represents the planned unit axis arranged in units of equipment, the vertical axis represents the time axis, and FIG. 8 shows the process plan and progress record of the management process for each part to be produced. FIG. 9 shows a vertical Gantt chart in which the process plan and progress results for each production process are shown in an overlapped manner. In addition, there is a tabular display method that shows a list of process plans and progress results based on product information as shown in FIG. 10, and three types of advanced display methods including the Gantt chart are used. A multi-viewer Gantt chart has been proposed.

Japanese Patent No. 4230852

  However, in the method of Patent Document 1, each process plan can be intuitively grasped in time series by using the vertical and horizontal Gantt charts, but if displayed for each process, the plan for each part is difficult to understand. Thus, since the plan for each process becomes difficult to understand when displayed for each part, there is a problem in that the plan and the result for each part and each process cannot be confirmed at the same time. Further, since the table format can display detailed information, it is useful when instructing work, but it is difficult to grasp intuitively and is unsuitable for grasping the entire work process.

  The present invention has been made in view of such circumstances, and can simultaneously manage a plan for each process and a plan for each part, and intuitively grasp the entire work process. An object of the present invention is to provide a schedule management apparatus, a management method thereof, a management program, and a schedule management system including the same.

In order to solve the above problems, the present invention employs the following means.
The present invention is a schedule management apparatus for managing a production schedule of parts, and includes a part number axis indicating a part number for identifying the part and a process axis indicating a production process of the part to be produced In the area, the pacemaker that is the target of the current production process determined based on the production schedule and the entity information that is the current progress state of the production process are included, and the pacemaker and the entity information are different. Provided is a schedule management device comprising presentation control means for presenting in the display area in a display format.

According to such a configuration, the pacemaker and the entity information are displayed in different display formats in the display area having the part number axis indicating the part number for identifying the part and the process axis indicating the production process of the produced part. The target of the current production process determined based on the part production schedule is shown as a pacemaker, and the progress status of the current production process is shown as entity information.
Thereby, since the progress state of the current production process is shown together with the target of the production process that should be originally present, it is possible to easily grasp when there is a delay or advance in the production process. In addition, in a display area composed of a part number axis indicating the part number and a process axis indicating the production process, the target and entity information (current progress state) for each process, and the target for each part Since the entity information is shown, the overall status of the production schedule can be grasped intuitively.

  The presentation control means of the schedule management device may indicate an identification number for identifying an application destination in the pacemaker and the entity information.

  Thereby, even if the same parts are produced at the same time, the progress state corresponding to each application destination can be grasped.

  The presentation control unit of the schedule management device indicates the pacemaker corresponding to the entity information whose process is progressing as planned in the production schedule in a first color, and the process proceeds as planned in the production schedule. The pacemaker corresponding to the entity information that is not present may be indicated by a second color different from the first color.

  Thereby, when a pacemaker is shown with the 1st color, it can grasp intuitively that a production schedule is as planned. Here, the “color” includes a hue to be colored and a pattern type indicated by diagonal lines or dots. Further, the case where the process is not progressing as planned in the production schedule includes process delay and process progress. It should be noted that the progress of the process takes into account that the stock becomes surplus and is not preferable for inventory management.

  The presentation control means of the schedule management device includes the production schedule plan and the produced delay among the pacemakers corresponding to the entity information in which a process is delayed with respect to the production schedule plan. The pacemaker whose time difference is less than or equal to the threshold value may be indicated by a third color different from the second color.

  If there is a pacemaker indicated by the third color, it is possible to intuitively understand that the time difference between the production schedule plan and the delay that has occurred is less than the threshold value, so it supports the pacemaker indicated by the third color. Therefore, it is possible to deal with such as preferential processing of the parts of the entity information to be processed, which is effective in correcting the deviation of the production schedule plan. Here, it is preferable to set a time difference having a possibility of recovering the delay and achieving the plan by taking measures such as preferential processing.

It is preferable that the presentation control means of the schedule management device indicate the entity information of the part and the pacemaker corresponding to the entity information in the same color.
By indicating the entity information and the pacemaker corresponding to the entity information in the same color, the progress state of the entity information can be easily grasped.

The presentation control means of the schedule management device may hide the corresponding pacemaker in the display area when the current progress status of the entity information is as planned in the production schedule. .
In the production process as planned, the display area can be prevented from becoming complicated by hiding the pacemaker.

The presentation control means of the schedule management device includes a defective area indicating that the production process is stopped in the display area, and indicates the entity information where the production process is stopped in the defective area. It is good as well.
It is possible to easily grasp the presence / absence of entity information of a part whose production process is stopped.

  In the above schedule management device, backward means for determining a first schedule in the backward starting from an assembly required date that is a date required for assembling the part into a product, and the production process of the part The process is classified into three types of processes: a normal process that performs processing, a large-capacity process that does not perform hill-climbing processing, and an outsourcing process in which the delivery date of the part is determined. It is good also as providing the schedule determination means which determines the said production schedule based on.

  After categorizing the production process of parts into three types of processes, a normal process that processes the landslide, a high-capacity process that does not perform landscaping with high processing capacity, and an outsourcing process that has a delivery date determined, By determining, a process that does not need to be crushed is not crushed compared to the case of crushed uniformly, so that the calculation cost can be reduced. In the case of an outsourcing process in which the delivery date of a part is determined by a contract or the like, it is possible to contribute to the determination of a simple production schedule by specifying the delivery date.

  The schedule determination unit of the schedule management device may be configured such that when the normal process includes an operation using a plurality of different types of resources, one process is an operation using a single type of resource. It is preferable to virtually divide the process.

  In the normal process, when an operation using a plurality of different types of resources is included, the process is virtually divided so that the resource of one process becomes a single type of resource. Here, the resources include “operating time” that is the time during which equipment and workers can operate, “resource number” that is the number of facilities and workers, and “number of heads” that are the number of parts that can be simultaneously operated if synchronized. including.

  The present invention provides a schedule management system comprising any one of the schedule management apparatuses described above and a client terminal connected to the schedule management apparatus via a network.

  The present invention relates to a management method for a schedule management apparatus that manages a production schedule of parts, a part number axis indicating a part number for identifying the part, and a process axis indicating a production process of the part to be produced. A pacemaker that is the target of the current production process determined based on the production schedule, and entity information that is the current progress state of the production process, and the pacemaker and the entity information Is provided in the display area in a different display format.

  The present invention is a management program for a schedule management apparatus that manages a production schedule of parts, a part number axis indicating a part number for identifying the part, and a process axis indicating a production process of the part to be produced. A pacemaker that is the target of the current production process determined based on the production schedule, and entity information that is the current progress state of the production process, and the pacemaker and the entity information Is provided in the display area in a different display format, and a management program for the schedule management apparatus is provided.

  The present invention has an effect that a plan for each process and a plan for each part can be managed simultaneously, and the entire work process can be grasped intuitively.

  Embodiments of a schedule management device, a management method thereof, a management program, and a schedule management system including the schedule management device according to the present invention will be described below with reference to the drawings.

[First Embodiment]
In the present embodiment, the case where the schedule management apparatus is used for management of a production schedule for producing parts constituting an aircraft will be described as an example, but the present invention is not limited to this.
FIG. 1 is a functional block diagram showing the functions provided in the schedule management system 1 in an expanded manner. As shown in FIG. 1, the schedule management system 1 includes a client 3, a schedule management device 10, a storage unit 4, and a site terminal 5. The client 3 and the schedule management device 10 are connected via the network 2 so that information can be exchanged. The schedule management device 10 is connected to the storage unit 4 and reads information from the storage unit 4 or stores information in the storage unit 4.

  The client 3 is a so-called computer system, and is a main storage device (not shown) such as a CPU (Central Processing Unit) (not shown), a RAM (Random Access Memory), a ROM (Read Only Memory), a HDD (Hard Disk Drive). ) And the like, an input device 30 such as a keyboard and a mouse, an output device 31 such as a display and a printer, a communication unit 32 that communicates with an external device, and the like. The client 3 is a terminal operated by a production schedule user (operator). The client 3 is equipped with a display application (for example, a WEB browser), and a display area (details will be described later) A via the output device 31 and the display application based on a command acquired from the schedule management device 10. Present.

  The on-site terminal 5 is a terminal operated by an on-site person in charge of the production process, and the progress status regarding the production process of the part (entity) currently in the production process is input as information (entity information). It is like that. As an input method, for example, information is acquired from a work record recorded by an input to the field terminal 5 using a touch panel, a keyboard, a mouse or the like, a method using an identification tag such as a barcode or an RFID tag, and a facility used. The method etc. are mentioned, It does not specifically limit. Information regarding the production process input from the on-site terminal 5 is output to the schedule management apparatus 10 via the network 2.

FIG. 2 is a block diagram illustrating a schematic configuration of the schedule management apparatus 10 according to the present embodiment.
As shown in FIG. 2, the schedule management apparatus 10 according to the present embodiment is a computer system (computer system), a CPU (Central Processing Unit) 11, a main storage device 12 such as a RAM (Random Access Memory), an auxiliary The storage device 13 includes an input device 14 such as a keyboard and a mouse, an output device 15 such as a display and a printer, and a communication device 16 that exchanges information by communicating with external devices.

  The auxiliary storage device 13 is a computer-readable recording medium, such as a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, or a semiconductor memory. Various programs (for example, a schedule management program) are stored in the auxiliary storage device 13, and the CPU 11 reads out the programs from the auxiliary storage device 13 to the main storage device 12 and executes them to implement various processes.

Next, processing contents executed in each unit included in the schedule management apparatus 10 described above will be described with reference to FIG. 1 are realized by the CPU 11 reading the schedule management program stored in the auxiliary storage device 13 into the main storage device 12 and executing it. .
The schedule management apparatus 10 includes a presentation control unit (presentation control means) 22.
The storage unit 4 stores a production schedule related to the production process of parts.

  The presentation control unit 22 presents a current value determined based on a production schedule in a display area A having a part number axis indicating a part number for identifying a part and a process axis indicating a production process of the produced part. The pacemaker that is the target of the production process and the entity information that is the current progress state of the production process are included, and the pacemaker and the entity information are presented in the display area A in different display formats. Specifically, the presentation control unit 22 determines the current process of the entity information based on the information regarding the production process of the parts acquired from the on-site terminal 5, and based on the production schedule read from the storage unit 4, the pacemaker The current process is determined, and the entity information and pacemaker are displayed on the display area A.

  In addition, the display control unit 22 includes the defect area X indicating the substance information where the production process is stopped in the display area A, and indicates the substance information where the production process is stopped in the defect area X. For example, when the presentation control unit 22 acquires defect information indicating that the production process is stopped due to a defect or the like (hereinafter referred to as “non-conforming state”) from another system or the like (not shown), the non-conforming state Is moved from the part number axis to the defective area X and displayed. Further, even if the system is not linked to other systems or the like, based on a command (instruction) from the client 3, the entity information of the nonconforming state is manually moved from the part number axis to the defective area X (for example, a mouse And drag and drop operation). It should be noted that display / non-display may be switched by setting or the like so that the defective area X is not displayed in the display area A.

  The presentation control unit 22 preferably indicates an identification number for identifying the application destination of the part in the pacemaker and the entity information. For example, when the part to be produced is a part of an aircraft wing, an aircraft identification number for identifying the aircraft to be applied is shown in the display area A.

  In addition, the presentation control unit 22 indicates the pacemaker corresponding to the entity information whose process is progressing as planned in the production schedule in the first color (for example, green), and the entity whose process is not progressing as planned in the production schedule A pacemaker corresponding to the information is indicated by a second color (for example, red) different from the first color. Further, the presentation control unit 22 is a pacemaker whose time difference between the production schedule plan and the produced delay is equal to or less than a threshold among the pacemakers corresponding to the entity information in which the process is delayed with respect to the production schedule plan. Is shown in a third color (eg, yellow) different from the second color.

  Here, it is preferable that the threshold value is set to a time difference that has a possibility of recovering the delay and taking it as planned by taking measures such as preferential processing even when the delay occurs. For example, when there is a pacemaker indicated by the third color (for example, yellow), the operator gives an instruction to the field staff to preferentially process the parts indicated by the third color. Thus, the delay in the production schedule can be quickly recovered.

  In the present embodiment, the first to third “colors” are indicated by hues, but the present invention is not limited to this. The “color” only needs to be able to identify different types of pacemakers. For example, a pacemaker of the first color has a white display with only a frame line, a pacemaker of the second color has a hatched display in the frame, The three color pacemakers may show different types of gray scale patterns by changing the gray scale pattern, for example, by displaying dots within the frame.

In addition, preferably, the component entity information and the pacemaker corresponding to the entity information are shown in the same color. As a result, the operator confirms the color of the pacemaker so that the progress status of the corresponding entity information can be easily grasped. Further, when the progress state of the current entity information is as planned in the production schedule, the presentation control unit 22 preferably hides the pacemaker corresponding to the entity information as planned in the display area A. This can prevent the display area A from becoming complicated.
In this way, when the presentation control unit 22 outputs a presentation command related to the display area from the schedule management apparatus 10 to the client 3, the display area A of the output device 31 of the client 3 is shown in FIG. A screen like this is displayed.

  FIG. 3 shows an example of a production schedule screen displayed in the display area A of the output device 31 of the client 3 based on the presentation command acquired from the presentation control unit 22. In the present embodiment, the production schedule screen displayed in the display area A of the output device 31 is referred to as a “product control board”. In the present embodiment, the application for displaying the product control board is described as being a WEB browser. However, the application is not limited to this, and a dedicated application for displaying the product control board may be used. Good.

As shown in FIG. 3, at the center of the product control board, there are part number axes in which part numbers (for example, #AAAAA, #BBBB) are indicated in the vertical direction, and work contents necessary for manufacturing parts in the horizontal direction. A table is provided in which the process axes shown are provided. The rightmost end of the process axis indicates the final process (reception / stock) indicating that the part manufacturing is finished.
The square frame shown at the position of the intersection between the part number and the process in the table is the identification number of the aircraft that is the application destination (attachment destination) of the part with the part number (for example, # 001 is the # 001 aircraft) A solid-line square frame indicates entity information indicating the current progress state, and a dotted-line square frame indicates a pacemaker that is a target of the current production process determined based on the production schedule.

  Also, as shown in FIG. 3, the square frame is color-coded with different patterns, but when the frame is white (for example, # 001, # 005, etc.), the process is proceeding as planned in the production schedule. It is a pacemaker corresponding to the entity information and the entity information. A square frame indicated by a dot (for example, # 008) in the frame indicates entity information that has not been processed as planned in the production schedule and a pacemaker corresponding to the entity information. In the square frame indicated by diagonal lines (for example, # 002, # 003, etc.), the process does not proceed as planned in the production schedule, and the process is delayed. The entity information whose time difference from the generated delay is equal to or less than the threshold and the pacemaker corresponding to the entity information are shown. In the table, the shaded nonconformity column indicates the defective area X. Here, it is preferable to set a time difference having a possibility of recovering the delay and achieving the plan by taking measures such as preferential processing.

  In the upper part of the table shown in the center of FIG. 3, a check box for specifying whether or not to display a pacemaker (for example, a setting to display when a check box is checked), and whether or not to display an alarm relating to hand holding amount Shows a check box that does. For example, if the check box for the alarm regarding the amount of handheld is checked, the equipment and resources set for each process will be displayed in the table when the preset number of handhelds for each equipment and resource is exceeded. Change the background color of the column. The set color may use a plurality of hues stepwise, or may use diagonal lines or dots.

  Here, the setting to make the color different for parts that have a delay or advance more than a predetermined number of days as a threshold compared to the planned date of the production schedule (plan schedule to which process work is assigned) is enabled The “schedule date” item is marked with ●. Also, for example, when the item of “comment” is changed from ○ mark to ● mark (for example, changed by clicking on the ○ mark), a square frame that includes a comment of a production person in charge in association with the part If you change the color of the item, or if you change the “Stay Days” item from ○ to ● (for example, click to change it), the number of days that the process stays However, it is possible to switch the display such as setting to change the color of the square frame when it is longer than the predetermined number of days.

  Further, when the mouse cursor is moved to the component entity information, the pacemaker corresponding to the entity information is highlighted on the display screen. For example, only when the mouse cursor is set, highlighting displays a square frame indicating the pacemaker and the entity information in a blinking or thick frame so that the association between the entity information and the pacemaker is easily visible. Alternatively, only when the mouse cursor is set, a straight line L may be drawn between the entity and the pacemaker to make the association easier to visually recognize.

Further, as shown in the small window Y of FIG. 3, a part of detailed information regarding the part with the mouse cursor is displayed. In a case where detailed information is displayed in more detail, an operation such as double-clicking on a square frame can be performed to present a component pop-up screen as shown in FIG.
Further, when the manufactured part is assembled at the application destination, when the “part assembly completion” button shown at the lower left of the part pop-up screen shown in FIG. 4 is pressed (by the user via the client 3). Information indicating that the assembly is completed is output to the schedule management apparatus 10. The schedule management apparatus 10 hides, on the product control board, the pacemaker and entity information corresponding to the part number (application destination) from which the part assembly completion information indicating that assembly has been completed is acquired.

Next, the operation of the schedule management system 1 according to the present embodiment will be described with reference to FIGS.
The progress state relating to the production process of the parts input from the field terminal 5 via the keyboard or the like by the person in charge who performs the work of the production process is output to the schedule management apparatus 10 via the network 2. The user of the production schedule operates the input device 30 of the client 3 and inputs a production schedule display command. When a display command is input to the schedule management device 10 via the network 2, the production schedule stored in the storage unit 4 is read out by the presentation control unit 22 of the schedule management device 10.

In the presentation control unit 22, the current progress state acquired from the worksite terminal 5 is compared with the production plan (planned date) included in the production schedule. As a result of the comparison, it is determined whether or not the vehicle is proceeding as planned, and if there is a delay from the plan, whether or not the delay is equal to or less than a threshold value. As a result of the determination, a presentation command for instructing an arrangement position and a display color with respect to the production process of the production process of the part information that is the production process and the pacemaker corresponding to the production information estimated from the production plan is sent to the client via the network 2. 3 is output. The client 3 displays a product control board as shown in FIG. 3 via the WEB browser based on the presentation command acquired via the communication unit 32.
The user of the production schedule can confirm that the process progresses as planned by checking the process steps and display colors of the entity information and the pacemaker from the display area presented on the output device 31, An instruction to preferentially process the delayed component can be issued.

As described above, according to the schedule management apparatus 10 and method and program according to the present embodiment, and the schedule management system 1 including the program, the part number axis indicating the part number for identifying the part and the part to be produced In the display area A having a process axis indicating the production process, the pacemaker and the entity information are displayed in different display formats, and the target of the current production process determined based on the production schedule of the parts is indicated as a pacemaker. The progress status of the production process is shown as entity information.
Thereby, since the progress state of the current production process is shown together with the target of the production process that should be originally present, it is possible to easily grasp when there is a delay or advance in the production process. Further, in the display area A configured by the part number axis indicating the part number and the process axis indicating the production process, the target and entity information (current progress state) for each process, and the target for each part Entity information is displayed, so that the overall status of the production schedule can be intuitively grasped.

  In the present embodiment, the presentation control unit 22 is described as determining the display process of the entity information indicating the current progress state based on the progress state information from the work site acquired from the work site terminal 5. However, the display method of the entity information is not limited to this. For example, in the case of a user who does not have the site terminal 5, based on the progress information obtained from the person in charge of manufacturing by the user, the entity information of the parts displayed on the WEB browser of the output device 31 of the client 3 is dragged and dragged. A drop operation may be performed to directly change the display position of the entity information, and information on the current progress state may be manually input by the user.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
The second embodiment differs from the first embodiment in that the schedule management device 10 determines a production schedule. Hereinafter, with respect to the production schedule apparatus of the present embodiment, description of points that are common to the first embodiment will be omitted, and different points will be mainly described.
As shown in FIG. 5, the schedule management apparatus 10 includes a backward unit (backward unit) 20 and a schedule determination unit (schedule determination unit) 21 in addition to the configuration shown in the first embodiment. Yes.

  The backward unit 20 determines the first schedule in the backward direction starting from an assembly required date that is a date required for assembling the parts into the product. Specifically, the backward unit 20 targets a process for which a production schedule is scheduled for a part for which a production schedule is to be determined, and sets a standard time set for each process sequentially from one working period. By subtracting, the planned scheduled date for each process is determined and set as the first schedule. Here, the standard time for each process is a time required for the work of each production process. For example, when the work system is a two shift system of daytime work and nighttime work, it is 8 hours from 18:00 to 17:00 after subtracting 1 hour of daytime = break, and night work = break 1 8 hours from 20 o'clock to 5 o'clock after subtracting the time is shown. The standard time for each process and the work period associated with the work system and the work system are respectively stored in the storage unit 4.

The schedule determination unit 21 has three types of processes: a normal process for crushed parts, a large-capacity process that does not perform a crushed process with high processing capacity, and an outsourcing process in which the delivery date of the parts is determined. The planned date is determined based on the classification result and the first schedule, and the production schedule is determined. The three types of processes will be described below with reference to FIG.
First, the normal process (type I) is a process planned in time units. Specifically, the work of each process is converted into hours, the standard number of hours of each process is assigned to one working period, and if there is a process that does not end within one working period, If you don't finish in the daytime, you will be assigned to work the night before.

In addition, in the normal process, when the work of each process is converted into the number of hours, when the work using a plurality of different types of resources is included in one process, the process is virtually divided into one process. Ensure that the process uses only a single type of resource. Here, the resource has three attributes of “operation time”, “number of resources”, and “number of heads”, and resource information and resource information associated with each work process are stored in the storage unit 4.
The operating time indicates the number of hours that can be operated. Specifically, the system startup time, the time required for setting, the morning time, the break time, and the time required for maintenance, etc. This is the number of hours that equipment and workers can operate, excluding time.

The number of resources indicates the number of parts that can work simultaneously asynchronously, and specifically, the number of facilities and the number of workers. For example, when the number of resources is plural, the operation time described above is multiplied by the number of resources.
The number of heads indicates the number of parts that can work simultaneously if synchronized, and specifically, is the number of heads of a processing machine or the like having a plurality of heads. When the number of heads is plural, the above-described operating time is multiplied by the number of heads under the condition that the heads operate at the same components and at the same timing.

  In addition, the process work of the normal process (type I) is considered to be a pile of resources such as equipment, workers, and jigs in each process. For example, when two part numbers #AAAA of application # 001 are created at the same time, as shown in FIG. 7, April 25 (FIG. 7 and hereinafter referred to as “4/25”) is assembled. As the necessary date, the backward schedule 20 determines the first schedule in the backward direction. The schedule determination unit 21 performs a mountain climbing process based on the resource attribute associated with the process set as the normal process, and determines the planned date. For example, as shown in FIG. 8, for example, normal processes “inspection”, “trim”, “mirror”, and “molding” of parts that are the same application destination are subjected to a mountain climbing process because resources overlap.

In addition, process operations such as “machining” that become a bottleneck due to simultaneous operation are classified as normal processes (type I) because it is preferable to perform a crushed process.
In this way, if one service period is a “bucket” and the work time for each part is “water”, the landslide process is to transfer the overflowing water to the previous work bucket. Equivalent to. Further, when the resource is compared with a bucket, the operation time corresponds to the capacity of the bucket, the number of resources corresponds to the number of buckets, and the number of heads corresponds to the number of special buckets.

Second, the high-capacity process (Type II) is a process having a large processing capacity compared to the normal process of Type I, and the planned date that is a schedule calculated in the backward direction is used as the planned date. This is a step of determining (deciding). In other words, the large-capacity process is a pile plan in units of days required for the plan. For example, a process operation whose time is estimated in advance, such as a surface treatment, is classified as a high-capacity process (type II).
Thirdly, the outsourcing process (type III) is a process in which a delivery date is determined by a contract with a customer or the like, and the delivery date is determined as a planned date. It is assumed that each time a part is completed, the part is not delivered to the customer, but a plurality of parts are delivered to some extent. In addition, when a process contradiction occurs between the planned date determined for Type I and Type II and the planned date for Type III, it is necessary to take measures such as changing the delivery date. The subcontracting process is a delivery date designated plan.

Hereinafter, the operation of the schedule management system 1 according to the present embodiment will be described with reference to FIGS. 1 and 9.
When a production schedule planning command is input from the client 3, the planning command is transmitted to the schedule management device 10 via the network 2. When the schedule management device 10 obtains a production schedule planning command, it is information on parts that are not in conformity or scrap, and the production process has not been completed (the final process has not been reached). ), Parts that have not been assembled are read (step SA1 in FIG. 9). Here, the assembly required date is selected within a predetermined threshold (for example, 2 weeks).

If there is a type III process among the read out parts, the delivery date of the type III process is determined as the planned date (step SA2 in FIG. 9). Work A = The daytime working time zone of the farthest future assembly required day is selected as the starting point (step SA3 in FIG. 9). From the selected starting point “work A”, process operations other than type III are backward processed, and the first schedule is determined (step SA4 in FIG. 9).
A process for which the planned date to be processed by work A is not fixed (for example, the initial value is the final process, which is a manufacturing completion process) is selected (step SA5 in FIG. 9), and it is determined whether it is a type I process. (Step SA6 in FIG. 9). Since a process that is not type I, that is, type II, does not need to be crushed, the process determines work A as a planned date (step SA10 in FIG. 9).

  In the case of Type I, the indeterminate time of the selected process (the initial value of the indeterminate time is set as the standard time) is subtracted from the total number of hours in work A of the resource used in the process work (see FIG. 9 step SA7). It is determined whether or not the subtraction result is 0 or more (step SA8 in FIG. 9). If the subtraction result is 0 or more, the process work plan is confirmed (step SA10 in FIG. 9). When the subtraction result is less than 0, it is assumed that “a landslide has occurred”, the absolute value of the negative value is set to the indeterminate time of the process operation, the plan of the process operation is not confirmed, and the The total number of hours of resource work A is 0 (step SA9 in FIG. 9).

  As described above, after the planned date of the selected process is confirmed (step SA10 in FIG. 9), or after a landslide has occurred (step SA9 in FIG. 9), the plans of all process work of work A are confirmed or It is determined whether or not the mountain climbing process has been performed (step SA11 in FIG. 9), and if there is a process in which neither the plan decision nor the mountain break process has been performed, the process returns to step SA5 to determine the planned date. A process that is not selected is selected. In this way, this process is repeated for all process operations determined as work A in the backward scheduling of step SA4.

  When plans for all processes of work A have been confirmed, or when a landslide has occurred, it is determined whether there is a process for which a planned date is not confirmed in a work period other than work A (FIG. 9). Step SA12), if the planned dates for all processes have been confirmed, a production schedule is created based on the determined planned dates, stored in the storage unit 4 (Step SA15 in FIG. 9), and this process is terminated. To do.

If there is still a process for which the planned date is not confirmed (Yes in step SA12 in FIG. 9), the next work period is set to work A = work (A-1), and the previous work (that is, work) If A = 4/26 daytime work, work (A-1) = 4/25 night work) is targeted (step SA13 in FIG. 9). It is determined in step SA9 in FIG. 9 whether or not a landslide has occurred (step SA14 in FIG. 9). If no landslide has occurred, the process returns to step SA5 and the work (A-1) process is completed. Determine the planning date.
If a mountain break has occurred in step SA9 in FIG. 9, the process returns to step SA4, and the process work whose planned date is not fixed is backward-processed starting from work (A-1), and the first schedule Create again. If a mountain break has occurred at work A, a process having an indeterminate time is selected (step SA5 in FIG. 9), and since the mountain break has occurred, the process proceeds to step SA7 because it is a type I process. Subtract the undefined time from the total number of hours of work (A-1), and repeat the subsequent processing.

Hereinafter, the above-described production schedule planning method will be described more specifically with reference to FIGS. An example of the production schedule planning method for part numbers #AAAAA and #BBBB of application number # 001 and part numbers #AAAAA and #BBBB of application number # 002 in FIG. 7 will be described.
In the product control board of FIG. 7, the identification numbers of the parts (for example, #AAAA, #BBBB) are shown in the vertical direction, and the identification numbers (for example, # 001, ##) of the application destinations of the parts corresponding to the horizontal direction are shown. 002 ...) is shown.

The assembly required dates of # 001 and # 002 are input by the user via the client 3 (or are acquired from another system not shown) and the assembly required date of # 001 is “4”. On the 25th of the month (hereinafter referred to as “4/25”), the assembly required date of the # 002 unit is set as “April 26 (hereinafter referred to as 4/26)” (see FIG. 7 (1)).
The work contents of the production process of part #AAAA and part #BBBB are “molding”, “conveyance”, “mirror”, “trim”, “inspection”, “surface treatment (surface treatment)”. It is assumed that the time required for the work is stored in the storage unit 4.

  Further, “inspection”, “trim”, “mirror”, and “molding” are type I, “surface treatment” is type II, and “conveyance” is a type III process. Further, in the present embodiment, the production process of parts #AAAAA and #BBBB is described as an example of the same work content, but is not limited thereto, and the work content in the production process of each part may be different. Good. When the schedule management device 10 obtains a production schedule planning command, it is information on parts that are not subject to planning, such as nonconformity status and scrap status, and the production process has not been completed and assembly has not been completed. For example, # 001 and # 002 are read out as parts.

  Among the read # 001 and # 002, as the type III process, #AAAA and #BBBB “conveyance” is the night of April 23 (hereinafter referred to as “4/23”) With “work” as the planned date, #AAAAA and #BBBB “transport” of # 002 machine determines the daytime work on April 24 (hereinafter “4/24”) as the planned date. Subsequently, 4/26 daytime work is selected as the starting point as the daytime working hours of the farthest future assembly required day. From 4/26, process operations other than type III are backward processed and the first schedule is determined (see FIG. 7B).

(A) in FIG. 7 is the first schedule of the # 001 part #AAAA, (b) is the first schedule of the # 001 part #BBBB, (c) is the #AAA # 1 schedule of the # 002 unit, (D) has shown the 1st schedule of #BBBB of # 002 machine.
As the process plan to be processed on 4/26, the “process” of the final process is selected, and it is determined whether it is a type I process. Since the process is not type I, that is, a process of type II, the process is not broken down, and the process is determined to have a schedule date of 4/26 (see 4/26 daytime work in FIG. 8). .

In 4/26, there is no other process for which the plan is not fixed, so the plan for the daytime work of 4/26 in the production schedule is fixed. Subsequently, since there are other undecided processes in the # 001 and # 002 machines, the planning process is executed for the night shift of the previous work = 4/25.
It is determined whether or not it is a type I process in the #AAAA and #BBBB “tables” of # 001 and the #AAAA and #BBBB “inspection” of # 002 on 4/25 night work. Since # AAAA's “October” and #BBBB “October” of # 001 are Type II processes, 4/25 night work is determined as the planned date.

Since # BBBB's “inspection” of # 002 is a type I process, the indeterminate time (standard time) of # BBBB's “inspection” from the total number of hours of night work on 4/25 of resources used in “inspection” ) Is subtracted and it is determined whether or not it is 0 or more. In this example, when it becomes 0 or more, the # BBBB's “inspection” of # 002 unit is finalized by night work on 4/25. Similarly, since “inspection” of #AAAA of # 002 machine is a type I process, the indeterminate time of “inspection” of #AAAA from the total hours of 4/25 night work of resources used in “inspection” (Standard time) is subtracted, and it is determined whether or not 0 or more. In this example, when it becomes less than 0, the plan for “inspection” of #AAAA of # 002 machine is determined to be unconfirmed, and the mountain climbing process is performed.
For all processes (#AAAA and #BBBB “tables” of # 001 and #AAAA and #BBBB “inspections” of # 002) set for night work on 4/25, finalization of the plan or landslide As a result, the 4/25 night work plan is confirmed.

Due to the mountain climbing process, the standard time for the #AAAA “inspection” process of Unit # 002 has become an indeterminate time, and plans have not been finalized for other processes. Then, make a plan. During the daytime work on April 25th, # 001 #AAAA and #BBBB “inspection”, # 002 #AAAA “inspection” moved by mountain climbing, and # 002 #BBBB “trim” The process is included.
Since these processes are all Type I processes, in order, subtract the indeterminate time of each process from the total number of working hours of 4/25 of the resource used in each process, and determine whether it becomes 0 or more. , Finalize the plan, or perform a hill-climbing process. In this example, the # 002 #BBBBB “trim”, the # 002 #AAAA “inspection”, and the # 001 #BBBB “inspection” confirm the plan, and the # 001 #AAAA “#AAAA” The “inspection” was crushed. (See FIG. 8 (1)).

  In this way, the planning is repeated for all the processes, but as shown in FIG. 8, the “carrying” process in which the planning date was initially determined as the process of type III is the above-described mountain climbing process. If there is a discrepancy due to this, measures such as changing the delivery date according to the discrepancy are taken. For example, in FIG. 8, the parts of application # 002 are “conveyed” so that two parts are conveyed simultaneously in time for the earlier process (ie, “mirror” of the 4/24 daytime work plan). "4/23 daytime work is scheduled. In this way, the production schedule corresponding to the application destination of each part is determined. 8A is the production schedule for # 001 part #AAAA, FIG. 8B is the production schedule for # 001 part #BBBB, and FIG. 8C is the production schedule for # 002 part #AAAA. , And (d) ′ show the production schedule of the part #BBBB of # 002 machine.

  As described above, according to the schedule management apparatus 10 and the method and the program according to the present embodiment, the production process of parts is a normal process for crushed processing, a large-capacity process having high processing capacity, and a delivery date. By categorizing into the three types of outsourced processes that have been determined and then determining the production schedule, processes that do not need to be crushed are not crushed compared to the case of crushed uniformly. The calculation cost can be reduced. In the case of an outsourcing process in which the delivery date of a part is determined by a contract or the like, it is possible to contribute to the determination of a simple production schedule by specifying the delivery date.

Also, in the normal process, when work using multiple resources of different types is included, the process is virtually divided so that the resource of one process becomes a single type of resource, and the number of operating hours is calculated By doing so, the schedule of the process work can be determined more accurately.
The process type (types I to III) is set for each process, and the resource attributes are set for the line containing multiple types of processes, making it easy and low in production costs. Production schedule can be drafted.
