Description

[Technical Field]

[0001] The present invention relates to a production management system. [Background technology]

[0002] Production using the individual order production method is known, such as high-mix, low-volume production and prototype manufacturing. The individual order production method refers to a form of production in which production objects are produced based on the individual specifications of each order. In the individual order production method, the specifications of the production objects differ for each order, so there are various work processes for the work that makes up the production objects. Therefore, it is not easy to manage production at each production facility.

[0003] Patent Document 1 describes a method for managing work instructions and work performance at a work site that uses an individual-to-order production system. Specifically, an ID tag is attached to the work to be worked on or near it, and at each work process, work instruction information is read from the ID tag of the work to be worked on that has been transported, and work is performed according to the work instruction information. When the work is completed, work performance information is written to the ID tag, and the work to be worked on is transported to the next work process. It is said that this makes it possible to manage work instructions and work performance. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-190120 Summary of the Invention [Problem to be solved by the invention]

[0005] However, there are cases in which production does not proceed according to the production plan. For example, in a certain work process, a work item may arrive late, making it impossible to carry out the planned work process. In this case, the delay in the work process affects the work in the subsequent process that targets that work, and the work in that subsequent process cannot be carried out as planned. This may require reworking the entire work plan.

[0006] In particular, in the individual order production system, the order of work processes varies depending on the work, the required time for each work process varies, and the work transport route is very complicated. Therefore, when multiple work processes are performed on the same work, it is not easy to understand how a delay in the arrival of a work at one work process will affect which work process.

[0007] However, in production, it is important to minimize delays in the delivery of a particular workpiece while preventing its impact on the production of other works. To achieve this, it is necessary to easily and quickly communicate information requiring attention, such as the existence of a workpiece that is arriving late, to workers in the affected work processes.

[0008] The present invention has been made in view of the above-mentioned problems, and aims to provide a production management system that can easily and quickly grasp information requiring attention, such as arrival delays, in an individual order production system. [Means for solving the problem]

[0009] One aspect of the present invention is a production management system that targets an individual order production system in which a plurality of production facilities are used to produce objects with individual specifications, and that manages the production of workpieces that constitute the objects, a server device including a database for storing production management data and a processor; a display device that forms a network capable of communicating with the server device; Equipped with the production management data includes a code representing the work, a code representing a plurality of work processes for the work, an order of the work processes for each of the work, a designated completion date for each of the work processes, and an arrival status of the work for each of the work processes; The display device includes: a calendar area including at least a date, configured so that a card corresponding to the work process can be arranged on a scheduled production date of the work process; an attention area configured to be displayed simultaneously with the calendar area and configured to allow the card to be placed when the work process of the card is in a attention-requiring state; Equipped with The processor: When the production management data is acquired, if the period until the designated process completion date is equal to or longer than a predetermined period, a process is executed to automatically arrange the card in the calendar area on a date determined based on the designated process completion date, and a process is executed to record position information of the card arranged in the calendar area in the production management data; When the production management data is acquired, if the period until the designated process completion date is less than the predetermined period, a process is executed to automatically place the card in the caution area, and a process is executed to record position information of the card placed in the caution area in the production management data. The production management system executes a process of displaying the arrival status included in the production management data on the cards displayed in the calendar area and the attention area. [Effects of the Invention]

[0010] According to the production management system, the display device has a calendar area and a caution area. When production management data is acquired, a card corresponding to the target work process is placed in the calendar area if the period until the designated process completion date is equal to or longer than a predetermined period. In particular, the card is automatically placed in the calendar area on a date determined based on the designated process completion date. The date on which the card is placed can be a date corresponding to the designated process completion date, or a date a predetermined number of days before the designated process completion date.

[0011] Unless there are special circumstances, cards corresponding to previously acquired production management data are placed in the calendar area. By checking the calendar area, workers can ascertain which work processes have already scheduled production dates for a specified period from the present.

[0012] On the other hand, in the attention area, a card corresponding to the target work process is placed when production management data has been acquired and the period until the designated process completion date is less than the predetermined period. In other words, by checking the cards placed in the attention area, workers can easily understand that there are work processes for which a scheduled work date has not been determined within the predetermined period from the present. Then, workers can identify cards in the attention area at the time when production management data is imported. Therefore, workers can easily and quickly identify cards in the attention area.

[0013] Furthermore, the cards display the arrival status of work for each work process. If the work to be worked on has not arrived at a work process, that work process cannot be started. By checking the arrival status of the cards in the caution area, workers can easily understand that the work to be worked on has not arrived at that work process. Furthermore, naturally, work has not arrived at the work process performed after that work process. Therefore, workers performing subsequent work processes can understand that work has not arrived at that subsequent work process. In this way, in multiple work processes in which the same work is worked on sequentially, workers at each work process can understand the circumstances that prevent the work process for that work from being started. In other words, workers can easily and quickly understand caution information such as arrival delays.

[0014] As described above, according to the above-described embodiment, a production management system can be provided that can easily and quickly grasp information requiring attention, such as arrival delays, in an individual order production system. [Brief explanation of the drawings]

[0016] (Embodiment 1) 1.Configuration of Production Management System 1 The configuration of the production management system 1 will be described with reference to Figure 1. The production management system 1 targets an individual order production system in which multiple production facilities are used to produce objects with individual specifications, and manages the production of the objects. In particular, in this embodiment, the production management system 1 manages the production of the work that constitutes the objects.

[0017] The production management system 1 comprises a server device 2, an administrator terminal 3, a display device 4, and a user terminal 5, which form a network capable of mutual communication. The server device 2 comprises a database 2a and a processor 2b. The database 2a stores production plan data, production management data determined based on the production plan data, production equipment data, etc. The processor 2b processes the data stored in the database 2a and processes terminals 3, 4, and 5 that are configured to be able to communicate with the server device 2.

[0018] The manager terminal 3 is a terminal used by a manager who manages production. By accessing the server device 2, the manager terminal 3 can check various information and can also execute processes on the server device 2.

[0019] The display device 4 forms a network capable of communicating with the server device 2, and can display on a display screen display content according to processing by the processor 2b of the server device 2. The display device 4 is equipped with, for example, a touch panel or other input device, and can also perform input operations. The user terminal 5 forms a network capable of communicating with the server device 2. The user terminal 5 can receive predetermined notifications through processing by the processor 2b of the server device 2.

[0020] 2. Example of a production process An example of a production process for the individual-to-order production method will be explained with reference to Figure 2. Various types of mechanical products are taken as examples of the objects produced by the production process. Examples of the objects produced include industrial machinery such as machine tools and assembly equipment. However, the objects produced can also be automobile parts, electrical appliances, etc.

[0021] As shown in Figure 2, the production process using the individual order production method involves, for example, receiving an order, designing, parts manufacturing, assembly, inspection, and shipping in that order. Parts manufacturing involves, for example, parts processing and painting. Parts processing includes machining such as cutting, grinding, electrical discharge machining, pressing, and injection machining, as well as heat treatment. Painting is a process that is performed on some of the parts that are required. In the embodiment described below, production management for parts processing in the parts manufacturing process is described.

[0022] 3. Database 2a of server device 2 The data stored in the database 2a of the server device 2 will be described with reference to Figs. 3 to 5. In this embodiment, the description will be given taking as an example parts processing as one of the production processes shown in Fig. 2. However, the other production processes are configured in a similar manner. The database 2a of the server device 2 stores production plan data 11, production equipment data 12, production management data 13 determined based on the production plan data 11, and the like.

[0023] The production plan data 11 includes, for example, the data shown in Fig. 3. For example, the production plan data 11 includes the machine number, model, delivery destination, specified delivery date, etc. In addition to the data shown in Fig. 3, the production plan data 11 includes data on each production process as shown in Fig. 2. The production plan data 11 also includes option information, etc.

[0024] The production equipment data 12 includes information on equipment owned by each department, as shown in Fig. 4. The information on equipment owned includes information on the type of production equipment, the processes that can be produced, etc. A department is, for example, a group of production organizations.

[0025] As shown in FIG. 5, the production management data 13 includes the machine number (code for the object to be produced), model (type of object to be produced), product number (code representing the work), item name (name of the work), delivery destination, production department, code representing the production equipment in the production department, code representing the target work process among multiple work processes for the work (process code), sequence of work processes for each work (process sequence), work time required by workers (man-time required), work time required by production equipment (machine-time required), designated process completion date for each work process, scheduled arrival date of the work for each work process, work arrival date and time, process completion date, number of days to advance the designated process completion date, position on the board (position information on the display screen of the display device 4), operation number (number of days required for production determined from the reference schedule), presence or absence of assembly instructions (code representing that the work will be produced by assembling with other work), etc.

[0026] In other words, production management data 13 is generated for each work production process. The production management data 13 is determined by a production manager using production plan data 11 shown in Figure 3 and production equipment data 12 shown in Figure 4. However, the production management data 13 can also be determined automatically by program processing, without relying on the production manager.

[0027] 4. Display screen of display device 4 The display screen of the display device 4 will be described with reference to Fig. 6 to Fig. 8. In this embodiment, the description will be given taking as an example the parts processing as one of the production processes shown in Fig. 2. However, the other production processes are configured in the same way.

[0028] The following describes the display screen of the display device 4, but the same content is also displayed on the display screen of the administrator terminal 3. The administrator terminal 3 and the display device 4 are set to have different operation authorities.

[0029] The display device 4 is configured to be able to display a main screen 21 shown in Fig. 6 and Fig. 7 and a detailed information screen 22 shown in Fig. 8. In this embodiment, the display device 4 always displays the main screen 21 and pops up the detailed information screen 22. However, the detailed information screen 22 can also be switched from the main screen 21.

[0030] 6, the main screen 21 includes a display main element area 31 located at the top, a calendar area 32 occupying most of the right side of the screen, an attention area 33 located horizontally to the left of the calendar area 32, and a planned production load area 34 located below the calendar area 32 and the attention area 33. The main screen 21 can be configured to display only the calendar area 32, only the attention area 33, or only the planned production load area 34, as appropriate.

[0031] The main display element area 31 displays information about the main display elements for specifying the display target on the display screen. The main screen 21 displays information for each department in the production organization. As shown in Figure 6, the main display element area 31 displays a department selection field 31a, a production equipment selection field 31b, and a date selection field 31c.

[0032] 6, "4 Departments" is selected in the department selection field 31a of the display main element area 31, and information about "4 Departments" is displayed on the main screen 21. When the pull-down button in the department selection field 31a is selected, selectable department names are displayed in a pull-down menu, and when a department is selected in the menu, information about the selected department is displayed.

[0033] Furthermore, as shown in Fig. 4, each department owns multiple pieces of production equipment. Therefore, in Fig. 6, "Machine No. 2" is selected in the production equipment selection field 31b of the main display element area 31, and information about "Machine No. 2" of "Department 4" is displayed on the main screen 21. When the pull-down button in the production equipment selection field 31b is selected, the names of selectable production equipment are displayed in a pull-down menu, and by selecting production equipment from the menu, information about the selected production equipment is displayed.

[0034] Furthermore, the date to be displayed is written in the date selection field 31c of the main display element area 31, and the date can be input by directly inputting it or by selecting it from a calendar display.

[0035] The calendar area 32 is displayed in a display format that includes at least the date. However, in this embodiment, it is displayed in a display format that includes the date and time. The calendar area 32 is displayed, for example, with the date on the horizontal axis and the time on the vertical axis. At the top of the calendar area 32, tabs 32a for the production equipment "Unit 1," "Unit 2," and "Unit 3" that can be selected in the department to be displayed are displayed. In FIG. 6, the tab 32a for "Unit 2" is selected, and information about "Unit 2" is displayed in the calendar area 32. By selecting the tab 32a for another production equipment in the calendar area 32, the display content of the calendar area 32 changes.

[0036] The calendar area 32 is configured so that cards C corresponding to work processes can be placed at the scheduled production date and time of the work process. Cards C are placed at the scheduled production start time on the scheduled production date. For example, in the calendar area 32, cards C are placed at "8:00" and "12:00" on December 23rd. However, in the calendar area 32, cards C are also placed at times other than the currently displayed time. By scrolling the calendar area 32, it is possible to display other times.

[0037] Card C corresponds to each piece of data in the production management data 13 shown in Figure 5. In other words, there is one card C for each work production process. Therefore, card C is linked to the production management data 13 shown in Figure 5, and displays some of the information in the production management data 13.

[0038] Furthermore, the calendar area 32 is configured to be able to identifiably display the time range Ct corresponding to the required time for the work process of card C, which in this embodiment is the machine required time (shown in FIG. 5). For example, in the calendar area 32, card C placed at 8:00 on December 23rd indicates a machine required time of 4 hours, and the time range Ct from 8:00 to 12:00 is reported in an identifiably displayable manner. The identifiably displayed method is, for example, by adding color.

[0039] That is, a worker who views the calendar area 32 can know the time when the work process is to start, and can also know the time required for the work process.

[0040] The attention area 33 is configured to be able to be displayed simultaneously with the calendar area 32. The attention area 33 is configured to be able to place cards C similar to the cards C displayed in the calendar area 32. However, cards C placed in the attention area 33 are cards in a state requiring attention where the planned production date for the relevant work process has not been determined. Cards C for which the planned production date has been determined are placed in the calendar area 32 described above. The display content of cards C placed in the attention area 33 is the same as the display content of cards C placed in the calendar area 32. However, cards C can also display different content depending on the area.

[0041] In this embodiment, the caution area 33 is configured to be able to switch between screens that display a plurality of types of situations as caution states, and is configured to be able to place a card C on each of the screens.

[0042] In this embodiment, the caution-requiring status includes, for example, a "new acquisition target," a "target with assembly instructions," a "process start delay status," a "bridge production request status," and an "overload status." However, the caution-requiring status is changed as appropriate depending on the type of production. The caution-requiring area 33 displays tabs 33a to 33e corresponding to various situations as caution-requiring statuses at the top of the area. The "New" tab 33a corresponding to the "new acquisition target," the "Assembly" tab 33b corresponding to the "target with assembly instructions," the "Delay" tab 33c corresponding to the "process start delay status," the "Bridge" tab 33d corresponding to the "bridge production request status," and the "Overload" tab 33e corresponding to the "overload status." In FIG. 6, the "New" tab 33a is selected, and the caution-requiring area 33 contains a card C indicating a "new acquisition target" caution status. Selecting one of the other tabs 33b to 33e in the caution-requiring area 33 changes the display content of the caution-requiring area 33.

[0043] The caution area 33 functions as a "new area" when the "new" tab 33a is selected, as an "assembly instruction area" when the "assembly" tab 33b is selected, as a "process start delay area" when the "delay" tab 33c is selected, as a "bridge production request area" when the "bridge" tab 33d is selected, and as an "overload area" when the "over" tab 33e is selected.

[0044] The "New acquisition target" area is an area for placing cards C whose designated process completion date is less than a predetermined period (for example, a period set between 1 and 4 weeks) when the server device 2 newly acquires production management data 13. However, cards C included in other areas requiring attention are placed in other areas requiring attention, so cards C that are not included in other areas requiring attention are placed in the "New acquisition target" area. The predetermined period can be set to, for example, two weeks, and can be set arbitrarily depending on the type of production, etc.

[0045] The "Target with assembly instructions" area is an area for placing the card C of the target work when the production management data 13 includes a code indicating that the work is produced by assembling other work. The "Process start delay status" area is an area for placing cards C for which the designated process completion date has passed. The "Bridge production request status" area is an area for placing cards C for which delivery to a department other than the target department is desired. Here, bridge production is a term that means producing the same product in multiple factories. The "Overload status" area is an area for placing cards C for work processes that exceed the capacity of the production equipment in the target department.

[0046] The attention area 33 displays the number of cards C arranged on each screen of each tab 33a to 33e and the change in the status of the cards C (33f). For example, as shown in Fig. 6, the number in the circle 33f indicates the number of cards C arranged on the screen of the target tab. In addition, the color of the circle frame indicates, for example, the presence or absence of a newly acquired card C as a change in the status of the cards C.

[0047] Furthermore, each of the tabs 33a to 33e in the attention area 33 can be set to be shared with other departments. It is also possible to set only some of the tabs 33a to 33e to be shared with other departments. For example, it is recommended that card C placed in the "Bridge production request status" area be viewable by workers in other departments. It is also possible to set other departments to be shared with. For example, it is recommended to set only departments that own the same type of production equipment as the target department as the other departments to be shared with.

[0048] The planned production load area 34 is configured to be able to be displayed simultaneously with the calendar area 32, and displays the planned production load of the target production equipment on the date displayed in the calendar area 32. As shown in Fig. 6, for example, the planned production load for December 23rd in the planned production load area 34 is displayed as a bar graph showing the total machine required times of all cards C placed on December 23rd in the calendar area 32, and for example, the total planned production load time is displayed as 23 hours. In this way, the planned production load area 34 displays the planned production load for each production equipment for each planned production date.

[0049] Furthermore, the planned production load is displayed in the planned production load area 34, distinguishing between whether or not work has arrived. The total machine required time when work has arrived at the target operation process and the total machine required time when work has not arrived at the target operation process are displayed in stacked bar graphs.

[0050] Furthermore, the planned production load area 34 shows a 24-hour line, and production may be possible within 24 hours, but production will be impossible if it exceeds 24 hours. This display enables workers to understand that there is a problem with the allocation of the planned production day.

[0051] 7, the operator can move a card C between the calendar area 32 and the caution area 33 on the main screen 21 by operating the display device 4. The operator can move the card C from the calendar area 32 to the caution area 33, or from the caution area 33 to the calendar area 32.

[0052] Next, the detailed information screen 22 will be described with reference to Fig. 8. When card C on the main screen 21 shown in Fig. 6 and Fig. 7 is selected by double-clicking or the like, the detailed information screen 22 shown in Fig. 8 pops up.

[0053] The detailed information screen 22 displays detailed information related to the target card C. The upper area 22a of the detailed information screen 22 displays part of the production management data 13 shown in Fig. 5. The amount of information displayed in the upper area 22a of the detailed information screen 22 is greater than the amount of information displayed for card C on the main screen 21.

[0054] In the upper area 22a, "Position on board" displays the position information on the board of the production management data 13. The position information on the board is the position information of card C on the main screen 21, and for example, when card C is placed in the calendar area 32, it is displayed as "2021 / 12 / 23 9:00", and when card C is placed in the attention area 33, it is displayed as "Process start delayed" or "Overload", etc.

[0055] Furthermore, the lower area 22b of the detailed information screen 22 displays the status of all work processes for the work that is the target of the card C. In FIG. 8, the upper area 22a of the detailed information screen 22 displays information about the process code "ABC3," and the lower area 22b of the detailed information screen 22 displays the work processes other than the process code "ABC3" in chronological order. Furthermore, the lower area 22b of the detailed information screen 22 displays the planned date and, if there is an actual date, the actual date. Therefore, the worker can grasp the progress of the target work.

[0056] 5. Card C display content The display contents of card C will be described with reference to Figs. 9 to 12. Card C is limited in display size, so it is limited to the minimum information. Therefore, in this embodiment, by displaying various icons on card C, it is possible to display a lot of information in a small space while making it visually easy to understand.

[0057] 9(a), card C1 includes a display area 41 for the machine number of the production object, a display area 42 for the specified process completion date, a display area 43 for whether work has arrived, a display area 44 indicating whether it is a programming process or a debugging process, a display area 45 for the work code, a display area 46 for the work arrival date or expected arrival date, a display area 47 for the order of the preceding and following processes of the work process, a display area 48 for the work name, a display area 49 for the machine required time, and a display area 50 for work position information. However, the display contents of card C1 can be changed as appropriate.

[0058] As shown in Figure 9(a), all cards C1 have the machine number, designated process completion date, work code, work name, and machine required time written in display areas 41, 42, 45, 48, and 49. In Figure 9(a), nothing is written in the other display areas 43, 44, 46, 47, and 50.

[0059] As shown in Figure 9(a), when display area 43 is blank, it means that no work has arrived at the corresponding work process. When display area 44 is blank, it means that the corresponding work process is neither a programming process nor a debugging process. A programming process is, for example, a design process for a machining program for a machine tool, and a debugging process is a process for debugging a designed machining program. When display area 46 is blank, it means that no work has arrived at the corresponding work process, and the arrival date of the work has not been confirmed.

[0060] If the display area 47 is blank, it means that when multiple cards C1 related to the same work as the work process are placed in the calendar area 32, the planned work sequence obtained from the position information of the multiple cards C1 matches the sequence of the multiple work processes included in the production management data 13. In other words, it means that there is no problem with the planned production sequence of the multiple work processes for the work targeted by card C1. If the display area 50 is blank, it means that the position of the work in the work process cannot be determined.

[0061] Card C2 shown in Fig. 9(b) displays a date in display area 46 and an icon in display area 50, in comparison with card C1 shown in Fig. 9(a). The thin-print date in display area 46 in Fig. 9(b) indicates the expected arrival date of the work. The icon in display area 50 shown in Fig. 9(b) indicates that the work has arrived at a work process that is two or more steps before the target work process of card C2.

[0062] Card C3 shown in Fig. 9(c) displays a thin-print date in display area 46 and an icon in display area 50, in comparison with card C1 shown in Fig. 9(a). The icon in display area 50 shown in Fig. 9(c) indicates that the work has arrived at the work process immediately preceding the target work process of card C3.

[0063] Card C4 shown in Fig. 9(d) has a different display mode in display area 46 than card C3 shown in Fig. 9(c). Card C4 shown in Fig. 9(d) indicates that the expected arrival date of the workpiece has been manually entered by the production manager. In other words, a marker is added as a symbol indicating that the date has been manually entered.

[0064] Card C5 shown in Fig. 9(e) displays a thin-print date in display area 46 and an icon in display area 50, in contrast to card C1 shown in Fig. 9(a). The icon in display area 50 shown in Fig. 9(e) indicates that the immediately preceding operation step in the order prior to the operation step targeted by card C5 has been completed. However, the work has not yet arrived at the operation step targeted by card C5.

[0065] Card C6 shown in FIG. 10(a) is displayed in display areas 43, 46, and 50 for card C1 shown in FIG. 9(a). The icon in display area 43 in FIG. 10(a) indicates that work has arrived at the target work process of card C6, and further indicates that the work arrived before the specified process completion date. The bold date in display area 46 in FIG. 10(a) is the arrival date of the work at the target work process of card C6. In FIG. 10(a), a bold date indicating the arrival date is displayed, rather than a thin date indicating the expected arrival date. The icon in display area 50 indicates that work has arrived at the target work process of card C6, but the work process has not yet started.

[0066] Card C7 shown in Fig. 10(b) differs from card C6 shown in Fig. 10(a) in the display mode of display area 43. The icon in display area 43 in Fig. 10(b) indicates that a workpiece has arrived at the work process targeted by card C7, and that the workpiece arrived after the specified process completion date.

[0067] Card C8 shown in Fig. 10(c) has a different outer frame display style from card C7 shown in Fig. 10(b). The outer frame style of card C8 shown in Fig. 10(c) indicates that the initially set designated process completion date has passed.

[0068] Card C9 shown in Fig. 10(d) has a different display mode in display area 42 than card C7 shown in Fig. 10(b). Display area 42 in Fig. 10(d) indicates that the designated process completion date has been brought forward from the initially set date. The date in display area 42 is the designated process completion date after the move-up.

[0069] Card C10 shown in Fig. 10(e) differs from card C6 shown in Fig. 10(a) in the display mode of display area 50. The display of "Done" in display area 50 in Fig. 10(e) means that the work process targeted by card C10 has been completed.

[0070] Card C11 shown in Fig. 11(a) displays an icon in display area 47 in comparison with card C1 shown in Fig. 9(a). The icon in display area 47 in Fig. 11(a) indicates that an operation that should normally be placed after the target operation is now placed before the target operation. The icon in display area 47 in Fig. 11(a) is displayed in a flashing highlighted state.

[0071] Card C12 shown in Fig. 11(b) has a different icon in display area 47 from card C11 shown in Fig. 11(a). The icon in display area 47 in Fig. 11(b) indicates that an operation that should normally be placed before the target operation is now placed after the target operation. The icon in display area 47 in Fig. 11(b) is displayed in a flashing highlighted state.

[0072] Card C13 shown in Fig. 11(c) has a different icon in display area 47 from card C11 shown in Fig. 11(a). The icon in display area 47 in Fig. 11(c) means that the work processes before and after the target work process are located in reverse order before and after the target work process. In other words, this means that a work process that should normally be located after the target work process is now located before the target work process, and a work process that should normally be located before the target work process is now located after the target work process.

[0073] Card C14 shown in Fig. 11(d) has a different icon in display area 47 from card C11 shown in Fig. 11(a). The icon in display area 47 in Fig. 11(d) indicates that an operation that follows the target operation of card C14 is placed on the same day as the target operation. Even if they are placed on the same day, there is no problem as long as the time on that day is set so that the operation order is correct. However, in the case of the same day, there is a possibility that the order will be reversed, so the icon is displayed to call attention to this.

[0074] Card C15 shown in Fig. 12(a) has an icon displayed in the display area 44 for card C1 shown in Fig. 9(a). The icon in the display area 44 in Fig. 12(a) means that the target work process of card C15 is a program process. Card C16 shown in Fig. 12(b) has an icon displayed in the display area 44 for card C1 shown in Fig. 9(a). The icon in the display area 44 in Fig. 12(b) means that the target work process of card C15 is a debugging process.

[0075] As described above, by using different display modes like the cards C1 to C16, the worker can easily grasp the status of the target work process.

[0076] 6. Processing by Processor 2b of Server Device 2 The processing of the processor 2b of the server device 2 will be described with reference to Figs. 13 to 16. The processor 2b of the server device 2 performs processing to change the display content of the display device 4 to display content according to the state. The processor 2b executes multiple processes described below in parallel.

[0077] Figure 13 shows the production management data import process by processor 2b. As shown in Figure 13, processor 2b acquires production management data 13 (S1) and registers it in database 2a (S2). Next, processor 2b acquires a new work process from the production management data 13 registered in database 2a (S3).

[0078] Next, the processor 2b determines whether the period until the designated process completion date for the acquired new work process is, for example, two weeks or more (S4). If it is two weeks or more (S4: Yes), the processor 2b executes a process to automatically arrange the card C of the target new work process in the calendar area 32 on the main screen 21 of the display device 4 (S5). In detail, the processor 2b executes a process to automatically arrange the card C of the target new work process in the calendar area 32 on a date determined based on the designated process completion date for the target new work process.

[0079] For example, the processor 2b automatically places card C on the designated process completion date of the target new work process in the calendar area 32. Alternatively, the processor 2b may automatically place card C on the date that is a predetermined number of days before the designated process completion date of the target new work process in the calendar area 32.

[0080] If a card C has already been placed on the corresponding date in the calendar area 32, the processor 2b places the card C consecutively at the time following the already placed card C. However, the card is placed consecutively so that the machine-required times do not overlap.

[0081] On the other hand, if it is less than two weeks (S4: No), the processor 2b executes a process of automatically placing the card C of the target new work process in the attention area 33 (S6). Here, depending on the card C of the target new work process, it is placed in one of the areas of the tabs 33a to 33e of the attention area 33.

[0082] Next, processor 2b executes a process of recording the position information of card C in the production management data of database 2a (S7). That is, when card C is placed in calendar area 32, processor 2b records information on the date and time when card C is placed in calendar area 32 in the production management data. When card C is placed in caution area 33, processor 2b records information on caution area 33, particularly information on any of tabs 33a to 33e of caution area 33, in the production management data.

[0083] Next, it is determined whether there is a new next work process (S8), and if there is a next work process (S8: Yes), the process returns to S3 and repeats. If there is no next work process (S8: No), the process ends.

[0084] Fig. 14 shows the card moving process by the processor 2b. As shown in Fig. 7, on the main screen 21, the operator can move card C between the calendar area 32 and the caution area 33. The card moving process is the process shown in Fig. 7.

[0085] 14, the processor 2b determines whether or not a screen switching operation for the caution area 33 has been received (S11). The screen switching operation is, for example, a process of selecting one of the tabs 33a to 33e for the caution area 33. When the processor 2b receives the screen switching operation, it executes a process of switching the display screen of the caution area 33 to a screen corresponding to the screen switching operation (S12).

[0086] After the screen is switched, or if the screen switching operation has not been accepted (S11: No), the processor 2b determines whether or not an operation to move the card C between the calendar area 32 and the caution area 33 has been accepted on the main screen 21 of the display device 4 (S13). If the operation to move the card C has not been accepted (S13: No), the process returns to S11 and repeats the process.

[0087] When the processor 2b receives the move operation (S13: Yes), it executes a process of moving the display position of the card C in accordance with the move operation (S14). Subsequently, the processor 2b executes a process of recording the changed position information of the card C on the main screen 21 of the display device 4 in the production management data of the database 2a (S15). Subsequently, in response to the move operation, the processor 2b executes a process of displaying the number of cards C displayed on the tabs 33a to 33d of the caution area 33 and the change in the status of the cards C (S16).

[0088] That is, the worker can freely move cards C on the main screen 21. For example, if a workpiece does not arrive in a work process of card C placed in the calendar area 32 and the work process cannot be completed in time for the specified completion date, the worker moves the card C in the calendar area 32 to the "Delay" tab 33c.

[0089] This allows anyone who can view the display device 4 to easily understand that the card C is in a state requiring attention and that the start of the process is delayed. If necessary, the production manager can take appropriate measures, such as re-planning the work or checking the status of the work.

[0090] 15 shows the card display process by the processor 2b. As shown in FIGS. 9 to 12, various information is displayed on the card C. That is, the processor 2b performs a process for displaying appropriate information on the card C while referring to the production management data 13.

[0091] As shown in FIGS. 10(a) to 10(e), processor 2b executes a process for displaying information on whether or not work has arrived in display area 43 of card C (S21). In detail, processor 2b determines whether or not the work arrival date and time is recorded in production management data 13. If it is not recorded, processor 2b displays nothing in display area 43. If it is recorded, processor 2b determines whether or not the work arrival date and time is before the designated process completion date. If the work arrival date and time is before the designated process completion date, processor 2b executes a process for displaying the icon shown in FIG. 10(a) in display area 43. If the work arrival date and time is after the designated process completion date, processor 2b executes a process for displaying the icon shown in FIG. 10(b), (c), and (d) in display area 43.

[0092] Next, processor 2b executes a process to display the arrival date or expected arrival date of the work in display area 46 of card C, as shown in Figures 9(b) to (e) and 10(a) to (e) (S22). In detail, processor 2b determines whether or not the work arrival date and time is recorded in production management data 13. If it is recorded, that is, if the work has already arrived at the work process, processor 2b executes a process to display the work arrival date in production management data 13 in display area 46 of card C, as shown in Figures 10(a) to (e).

[0093] If the work arrival date and time is not recorded in the production management data 13, it means that the work has not arrived at the work process, and so processor 2b executes processing to display the expected work arrival date in the display area 46. First, processor 2b acquires the work arrival date or expected work arrival date for the same work as the work on card C at an earlier work process than the work process on card C. Next, processor 2b calculates a date by adding the number of days (step number) required for the work in the earlier work process to the acquired work arrival date or expected work arrival date at the earlier work process. Next, processor 2b executes processing to display this as the expected work arrival date for the work process on card C in the display area 46 of card C, as shown in Figures 9(b) to 9(e). As shown in Figures 9(b) and 10(a), processor 2b executes processing to display the display mode of the work arrival date and the display mode of the expected work arrival date separately on card C.

[0094] Furthermore, if the workpiece arrival date and time is not recorded in the production management data 13, the production manager can manually input the scheduled workpiece arrival date. Therefore, when the processor 2b receives a manual input operation for the scheduled workpiece arrival date, it stores the manually input scheduled workpiece arrival date in the production management data. Then, as shown in FIG. 9(d), the processor 2b executes a process to display a symbol indicating that the scheduled workpiece arrival date has been manually input in the display area 46 of the card C.

[0095] Next, it is determined whether the expected work arrival date has been manually input (S23), and if it has been manually input, processor 2b executes a process of recording a code indicating that it has been manually input in production management data 13. Next, if a code indicating that it has been manually input is recorded in production management data 13, processor 2b executes a process of notifying a preset terminal 5 (S24). The worker who receives the notification can revise the work plan taking the expected work arrival date into consideration. If it has not been manually input (S23: No), the notification process is not performed and the process proceeds to the next step.

[0096] Next, processor 2b acquires position information of a workpiece in an earlier work step than the work step on card C for the same workpiece as that on card C (S25). Then, processor 2b executes a process to display an icon indicating the position information of the workpiece in display area 50 of card C, as shown in Figures 9(b) to 9(e) (S26).

[0097] Next, processor 2b acquires the planned work sequence obtained from the position information of multiple cards C when multiple cards C related to the same work are arranged in calendar area 32 (S27). Then, processor 2b determines whether the acquired planned work sequence matches the sequence of work processes included in production management data 13 (S28). If the sequences do not match (S28: No), processor 2b executes processing to display a symbol indicating the mismatch in display area 47 of card C, as shown in Figures 11(a) to 11(d). If they match (S28: Yes), the processor proceeds to the next processing without performing processing to display the mismatch.

[0098] Next, processor 2b determines whether a change to the designated process completion date has been accepted (S30). If a change has been accepted (S30: Yes), processor 2b executes a process of changing the designated process completion date included in production management data 13 to the changed date and recording a code indicating that the designated process completion date has been changed in production management data 13. Furthermore, if the designated process completion date in production management data 13 has been changed, processor 2b executes a process of displaying a code indicating that the designated process completion date has been changed in display area 42 of card C, as shown in FIG. 10(d) (S31).

[0099] Next, processor 2b executes a process to notify a preset terminal 5 that the designated process completion date has been changed (S32). The worker who receives the notification can revise the work plan taking the designated process completion date into consideration. If the designated process completion date has not been changed (S30: No), the process ends without performing the change display process and notification process.

[0100] 16 shows the load display process by the processor 2b. The processor 2b acquires the target production equipment (S41). In the planned production load area 34 of the main screen 21, the target production equipment is the production equipment selected in the main display element area 31 of the main screen 21. In another screen (not shown), it can be set to target multiple production equipment.

[0101] Next, processor 2b calculates the planned production load for each target production facility for each planned production date based on production management data 13 (S42). If the planned production load display is to be differentiated based on whether or not work has arrived, the planned production load is calculated based on whether or not work has arrived. Next, processor 2b executes processing to display the calculated planned production load for each planned production date in planned production load area 34 of display device 4, as shown in FIG. 6. If the planned production load display is to be differentiated based on whether or not work has arrived, the processor executes processing to display the planned production load area 34 based on whether or not work has arrived.

[0102] 7.Effects According to the production management system 1, the display device 4 has a calendar area 32 and a caution area 33. When the production management data 13 is acquired, a card C corresponding to the target work process is placed in the calendar area 32 if the period until the designated process completion date is a predetermined period (for example, two weeks) or more. In particular, the card C is automatically placed in the calendar area 32 on a date determined based on the designated process completion date. The date on which the card is placed can be a date corresponding to the designated process completion date, or a date a predetermined number of days before the designated process completion date.

[0103] Unless there are special circumstances, cards C corresponding to previously acquired production management data 13 are placed in the calendar area 32. By checking the calendar area 32, workers can ascertain the work processes for which scheduled production dates have already been determined within a predetermined period from the present.

[0104] On the other hand, in the attention required area 33, a card C corresponding to the target work process is placed when the production management data 13 has been acquired and the period until the designated process completion date is less than a predetermined period (for example, two weeks). In other words, by checking the card C placed in the attention required area 33, the worker can easily understand that there is a work process for which a scheduled work date has not been determined within a predetermined period from the present. The worker can then understand the card C in the attention required area 33 at the time the production management data 13 is imported. Therefore, the worker can easily and quickly understand the card C in the attention required area 33.

[0105] Furthermore, card C displays the arrival status of the work for each work process. The arrival status of the work is, for example, an icon displayed in display areas 43, 50 of card C, as shown in Figs. 9 to 12. If the work to be worked on has not arrived at a work process, that work process cannot be started. By checking the arrival status of card C in the attention area 33, the worker can easily understand that the work to be worked on has not arrived at that work process.

[0106] Furthermore, it naturally follows that the work has not yet arrived at the work process that follows the current work process. Therefore, the worker performing the subsequent work process can understand that the work has not yet arrived at that subsequent work process. In this way, in multiple work processes in which the same work is worked on sequentially, the workers at each work process can understand the circumstances that prevent the work process for that work from starting. In other words, the workers can easily and quickly grasp information requiring attention, such as arrival delays. Therefore, according to the production management system 1, in an individual-to-order production system, it is possible to easily and quickly grasp information requiring attention, such as arrival delays.
