BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. The production control system 1 according to this embodiment is a system for managing the production of products, and the products are produced by a plurality of workers performing a plurality of work processes in accordance with predetermined quality control rules. Note that the work process is a set of predetermined work. A work process is usually set by two or more works, but may be set by one work. The work process may be performed by one worker, or may be performed by a plurality of workers under the supervision of one worker. In the following description, it is assumed that the work process is performed by one worker.

As shown in FIG. 1, the production management system 1 is composed of a record storage server 10, a work information server 20, a manager terminal 30, and a worker terminal 40, which can communicate with each other by wire or wirelessly via a network 2. ing.

The record storage server 10 is a server in which records of work processes performed by each worker are stored. A server is a computer that provides services. The record preservation server 10 is an example of a "record preservation unit" according to the present invention. By storing records of work processes in the record storage server 10, it is no longer necessary to store record documents, and it is possible to promote paperless operations. Further, by referring to the records stored in the record storage server 10, it is possible to check the details of the work processes that have already been performed after the fact. As a result, the quality of the work process can be checked even after the work process has been executed, and the work quality can be improved.

The work information server 20 is a server that stores various types of information about work processes. In this embodiment, as shown in FIG. 2, the work information server 20 includes a drawing/reference material storage unit 21 in which information on various drawings and reference materials related to the product is stored, tools and jigs used in manufacturing the product.

However, the information described here is only an example. Information stored in the work information server 20 is not limited at all.

The administrator terminal 30 is a computer used by a person (administrator) who manages work processes. As shown in FIG. 3 , the administrator terminal 30 includes an input device 31 , an information processing device 32 and a display device 33 . The information processing device 32 includes a transmission section 32A that transmits a signal, a reception section 32B that receives a signal, a display section 32C that displays a progress display image and the like, which will be described later, on the display device 33, a determination section 32D that performs determination described later, and a warning It has a display section 32E. The configuration of the administrator terminal 30 is not limited at all. The administrator terminal 30 may include, for example, a mouse and a keyboard as the input device 31 , a stationary personal computer as the information processing device 32 , and a liquid crystal display as the display device 33 . Alternatively, the administrator terminal 30 may be a notebook personal computer. Also, the administrator terminal 30 may be a portable information terminal such as a tablet computer or a smart phone having a touch panel as the input device 31 and the display device 33 .

The worker terminal 40 is a computer used by a person (worker) who executes a work process. As shown in FIG. 4 , the worker terminal 40 includes an input device 41 , an information processing device 42 and a display device 43 . The information processing device 42 includes a transmission section 42A that transmits a signal, a reception section 42B that receives a signal, a display section 42C that displays a work process image or the like described later on the display device 33, an image update section 42F that updates the work process image, It has a judgment section 42D for making a judgment, which will be described later, and a warning display section 42E. Although the configuration of the worker terminal 40 is not limited at all, it is a mobile information terminal such as a tablet computer or a smart phone in this embodiment. The input device 41 and the display device 43 are composed of a touch panel (not shown). By the way, a worker may work while changing the work place. In this embodiment, since the worker can carry the worker terminal 40 while moving, the work place can be changed without replacing the worker terminal 40 with another worker terminal 40 .

Note that the configuration shown in FIG. 1 is merely an example. The record preservation server 10 and the work information server 20 may be physically different servers, or may be physically the same server. The record preservation server 10 and the work information server 20 may be configured by one computer. Moreover, the record preservation server 10 may be configured by one computer, or may be configured by two or more computers. The work information server 20 may be composed of one computer, or may be composed of two or more computers. Although only one administrator terminal 30 is shown in FIG. 1, the number of administrator terminals 30 may of course be two or more. Although only four worker terminals 40 are illustrated in FIG. 1, the number of worker terminals 40 may be five or more. The number of worker terminals 40 is not limited at all.

In this embodiment, the work process includes a machining process and an inspection process. The work includes, for example, cutting work such as drilling and cutting, assembly work such as riveting, bolting, welding, and bonding, and polishing. The inspection is to check visually or using an instrument whether or not the above-mentioned work has been properly performed. There are some types of work that require inspection afterward, and others that do not. The workers referred to here include workers who carry out work and inspectors who carry out inspections.

The work process information storage unit 26 (see FIG. 2) of the work information server 20 stores a series of work process information for manufacturing a product. When a product is produced by a plurality of workers performing a plurality of work processes, each worker is assigned a part of the work processes. The manager confirms what kind of work processes are available and plans which work process is to be assigned to each worker.

FIG. 5 is an example of an image displayed on the display device 33 of the administrator terminal 30. As shown in FIG. As shown in FIG. 5 , the manager terminal 30 can obtain information about work processes from the work information server 20 and display a list of work processes on the display device 33 . Note that such a list is defined for each product or part to be manufactured. The manager can confirm what kind of work process exists by looking at the list of work processes. Here, the work process is uniquely specified by the job number (JOB No.) displayed in the leftmost column of the table. A job number is a symbol for identifying a work process.

FIG. 6 shows an image displayed on the display device 33 of the manager terminal 30, which is used when the manager plans what kind of work process is to be assigned to each worker. In the area A1 of this image, the names of the workers (workers P1 to P5, etc.) and the schedules of the workers are displayed. A series of work processes are displayed as blocks in the lower area A2. The manager can fill in the worker's schedule by dragging and dropping work process blocks from the area A2 to the area A1.

Some of the plurality of work processes have their order set in advance. The work process order is stored in the work process information storage unit 26 of the work information server 20 . In this embodiment, it is determined whether or not the order of the work processes is correct with respect to the worker's schedule drawn up by the manager. For example, if the order of work processes JA1, JA2, JA3, and JA4 is set, the manager drags and drops the block of work process JA5 next to the blocks of work processes JA1, JA2, and JA3 (Fig. 6). When a work process block is dragged and dropped, the determination unit 42D determines whether or not the order of work processes input by the manager matches the order stored in the work process information storage unit 26.例文帳に追加When the determination unit 42D determines that the orders do not match, the warning display unit 42E of the worker terminal 40 of the worker displays a warning on the display device 43 when the work process JA5 that does not match starts. Although the method of displaying the warning is not limited at all, for example, the dragged and dropped block may be displayed in red. The worker to whom the warning is displayed reports the content of the warning to a nearby manager, and the manager corrects the work process appropriately. In the case of a work process whose order is set in advance, the condition is set such that the related work is completed. For this reason, regarding the timing of the warning display in this embodiment, it is better to set the timing to match the timing of the actual work rather than the timing of the drag and drop, in order to satisfy the important condition "completion of the related work". It is valid. It is preferable not only for progress management but also for high quality control if the work order is changed after accurately grasping the completion of the related work. Note that it is also possible to display a warning immediately without hindering progress. For example, if an administrator erroneously sets the order of work processes when planning a worker's schedule, a warning may be displayed on the display device 33 of the administrator terminal 30 . Also, it may be possible to prevent drag-and-drop in the wrong order. As a result, it is possible to prevent the administrator from making an inappropriate schedule, and to prevent the worker from performing the work processes in the wrong order.

In this way, the schedule planning is completed when the manager distributes a series of work processes to a plurality of workers. Information on the planned schedule is transmitted to the worker terminal 40 of each worker. That is, the schedule information is transmitted from the transmitter 32A of the manager terminal 30 to the receiver 42B of the worker terminal 40. FIG.

FIG. 7 is an example of a work process image displayed on the display device 43 of the worker terminal 40. As shown in FIG. This image contains information about work processes to be performed by each worker. In an area B1 of this image, a list of the contents of work included in the work process is displayed. A worker can easily understand what kind of work should be done by looking at the list of work contents.

In addition, the worker can not only view the list of work contents, but also write additional information using the input device 41 (see FIG. 8). The administrator can also use the input device 31 to write additional information. In this embodiment, the worker terminal 40 has an information appending unit 42M that updates the work process image by adding the additional information to the list when the worker inputs the additional information (see FIG. 4). The function of adding information is also effective in discarding the input work process and inputting a new work process when an unexpected response is required in the work process. Moreover, if both a worker and a manager can be added, it is possible to respond flexibly, which is more effective. In particular, when a worker and an administrator share a role, if at least one of the terminals can be added, the work can proceed satisfactorily. The administrator terminal 30 also has an information appending unit 32M (see FIG. 3) that updates the work process image by adding the additional information to the list when the administrator inputs the additional information. As a result, it is possible to add information about the work process, such as matters noticed by the worker at the work site, notes that the manager wants to convey to the worker, and the like. However, the preset work contents (for example, the contents of Nos. 1, 2, and 3 in FIG. 8) cannot be edited so as not to be deleted or changed.

As shown in FIG. 7, in area B2, buttons 101 and 102 for referring to reference materials and attached materials are displayed. When the worker presses the buttons 101 and 102, information is transmitted from the drawing/reference material storage unit 21 of the work information server 20 to the worker terminal 40, and reference materials (drawings, etc.) and attached materials are displayed on the display device 43. Another image is displayed.

FIG. 9 is an example of an image displayed on the display device 43 of the worker terminal 40 and showing the worker's progress. A region C1 of this image displays the schedule (scheduled) of the worker, and a region C2 below the region C1 displays the progress (results) of the worker. Schedule and progress are represented by lining up work process boxes. The current time is displayed by a vertical bar 104, and the vertical bar 104 moves to the right as time progresses. This image shows buttons 105 for the operator to input the start and end of the work process. Before the start of the work process, the button 105 displays the word "Start". When the worker presses the button 105 labeled "Start", the start of the work process is recorded and the text on the button 105 is changed from "Start" to "Complete". In the middle of the work process, the button 105 displays the character "Complete". When the worker finishes the work process and presses the button 105, the end of the work process is recorded and the text of the button 105 is changed from "complete" to "start". When the operator presses the button 105 labeled "Start" again, the start of the next work step is recorded.

A standard work time is set in advance for a series of work processes performed by a worker. Remaining time is calculated by subtracting actual time spent from standard work time. The area C3 displays the remaining time as a bar, and the area C4 displays the remaining time as a numerical value (minutes). When a delay occurs, the operator may be notified by, for example, blinking the bar in area C3 or the numerical value in area C4.

The manager terminal 30 constantly communicates with each worker terminal 40 . As shown in FIG. 10, the display device 33 of the manager terminal 30 displays a progress display image representing the progress of each worker. The progress display image includes a plurality of areas D1 representing the progress of each worker. The upper area D11 of each area D1 displays the schedule of the worker, and the lower area D12 displays the schedule of the worker. Worker progress is displayed. The current time is displayed by a vertical bar 103, and the vertical bar 103 moves to the right as time progresses. The progress of the worker's work process is identified by the color of the box. For example, the boxes for unstarted operations are white, the boxes for operations being started are gray, the boxes for operations completed within the standard work time are blue, and the boxes for operations completed beyond the standard work time are red. , the manager can easily grasp the progress of the work process.

For example, the first worker's work process is behind schedule, the second worker's work process is ahead of schedule, and the first worker's subsequent work process is delayed by the second worker's subsequent work process. If the process takes longer than the work process, the manager can easily grasp that fact by viewing the progress display image. Then, the manager can change the schedule by, for example, switching the next work process of the first worker and the next work process of the second worker. The manager can easily change the schedule by performing drag & drop and replacing the blocks in the area D1 of the first worker and the blocks in the area D1 of the second worker via the movement area D5. can do.

When the manager changes the schedule, a signal is transmitted from the manager terminal 30 to the worker terminal 40, and the worker terminal 40 is notified of the schedule change. In the above example, the changed schedule is transmitted to worker terminals 40 of worker A and worker B. FIG. As a result, an image (not shown) representing the changed schedule is displayed on the display devices 43 of the worker terminals 40 of worker A and worker B. FIG. Worker A and worker B proceed with the work according to the changed schedule.

By the way, depending on the content of the work process, some work can only be performed by a worker who has the necessary qualifications (qualified person) or under the supervision of a qualified person. Such a work process is hereinafter referred to as a qualification process. Information on whether or not a work process is a qualification-required process and information on qualifications possessed by workers are stored in the qualification information storage unit 24 (see FIG. 2) of the work information server 20 . In this embodiment, when the administrator drags and drops a block to assign a work process to a worker as described above (see FIG. 6), the determination unit 32D of the administrator terminal 30 communicates with the work information server 20. to determine whether or not the worker has the necessary qualifications for the work process. When the determination unit 32D determines that the worker is not qualified, the warning display unit 32E causes the display device 33 to display a warning. Alternatively, when a worker starts a work process, the determination unit 42D of the worker terminal 40 communicates with the work information server 20 to determine whether the worker has the necessary qualifications for the work process. judge. When the determination unit 42D determines that the worker is not qualified, the warning display unit 42E causes the display device 43 of the worker terminal 40 to display a warning. As a result, it is possible to prevent an unqualified worker from executing the work process, and to ensure work quality.

However, even if the worker himself/herself is not qualified, the worker can perform the work process under the supervision of a qualified person. Therefore, the administrator terminal 30 is provided with a monitoring request transmission section 32G that transmits a signal requesting monitoring to the worker terminal 40 of a qualified person when the determination section 32D determines that the worker is not qualified. (see FIG. 3). The worker terminal 40 also includes a monitoring request transmission section 42G that transmits a signal requesting monitoring to the worker terminal 40 of a qualified person when the determination section 42D determines that the worker is not qualified. (see FIG. 4). The operator terminal 40 of the qualified person may include an approval request display section 42H that displays an image (not shown) requesting approval on the display device 43 upon receiving the signal (see FIG. 4). As a result, it is possible to quickly and accurately request the qualified person for approval and to perform the work of approval by the qualified person, and to efficiently proceed with the work process under the supervision of the qualified person.

Depending on the content of the work process, there are cases in which environmental conditions are defined when a worker performs the work process. For example, in a work process such as paint formulation, the temperature or humidity during work may be limited within a predetermined range. Such conditions are stored in the environment information storage unit 23 (see FIG. 2) of the work information server 20. FIG. In this embodiment, the determination unit 42D of the worker terminal 40 determines that the temperature and humidity when the worker inputs the start and end of the work process are within the temperature and humidity ranges stored in the environment information storage unit 23. It is determined whether or not there is The temperature and humidity are detected, for example, by a thermometer and a hygrometer installed at the work place, and the temperature and humidity information is transmitted to the worker terminal 40 from the thermometer and the hygrometer. When the determination unit 42D determines that the temperature and humidity are not within the above ranges, the warning display unit 42E causes the display device 43 to display a warning. In addition, the determination result of the determination unit 42D of the worker terminal 40 may be transmitted to the administrator terminal 30, and the warning display unit 32E of the administrator terminal 30 may cause the display device 33 to display a warning. As a result, it is possible to prevent a work process from being performed that does not conform to the temperature and humidity conditions, and to ensure work quality.

Also, depending on the content of the work process, there are cases in which the expiration date of materials required for the work process is set in advance. For example, in a work process such as assembly, an adhesive with a set expiration date may be used. In such cases, it is necessary to carry out the work steps before the expiration date of the adhesive. The condition regarding the expiration date of the material is stored in the material information storage unit 25 (see FIG. 2) of the work information server 20. FIG. In this embodiment, the determination unit 42D of the worker terminal 40 determines whether the date and time when the worker inputs the start or end of the work process exceeds the expiration date stored in the material information storage unit 25. judge. Then, when the determination unit 42D determines that the expiration date has been exceeded, the warning display unit 42E causes the display device 43 to display a warning. In addition, the determination result of the determination unit 42D of the worker terminal 40 may be transmitted to the administrator terminal 30, and the warning display unit 32E of the administrator terminal 30 may cause the display device 33 to display a warning. As a result, it is possible to prevent a work process using materials whose expiration date has passed, and to ensure work quality.

Also, depending on the content of the work process, there are cases where the tools used in the work process are limited to specific tools. Such tool-related conditions are stored in the tool/jig information storage unit 22 (see FIG. 2) of the work information server 20 . The tool used by the worker can be specified, for example, by the worker's input to the worker terminal 40 . The determination unit 42</b>D of the worker terminal 40 determines whether or not the tool used by the worker matches the tool stored in the tool/jig information storage unit 22 . When the determination unit 42D determines that they do not match, the warning display unit 42E causes the display device 43 to display a warning. Also in this case, the determination result of the determination unit 42D of the worker terminal 40 may be transmitted to the administrator terminal 30, and the warning display unit 32E of the administrator terminal 30 may cause the display device 33 to display the warning. . As a result, it is possible to prevent a work process using an inappropriate tool from being performed, and to ensure work quality.

Some of the work processes performed by the operator must be subsequently inspected by an inspector.
