In FIG. 2, 1 is a computer installed on the center side, 2 is a storage device, 3 is a video display device, 5 _{1 to} 5 _N are lots of processing materials, and # 1 to #M are processing materials 5 sequentially. Manufacturing process (process), 4
₁ to 4 _M is a data terminal for inputting data generated at each process step (e.g., a bar code reader reads the information in the bar code attached to each lot to generate various data), the data terminal 4 ₁ The data generated at 4 _N is collected by the computer 1 and stored in the storage device 2.

In this production system, the upstream manufacturing process #
When the lot 5 of the processing material is input from 1 to the downstream manufacturing process, the processing is sequentially performed in each of the manufacturing processes # 1 to #M, and finally the final process #M is dispensed as a product lot. In order to manage this flow, each manufacturing process # 1
~ #M creates information (eg, manufacturing lot number, manufacturing start date / time, manufacturing completion date / time, quantity of non-defective / defective product, name of manufacturing person, etc.) for each lot that has been input / dispensed in that process, It is sent to the computer 1 via the data terminal 4. The computer 1 collects this information,
Individual status information (hereinafter referred to as lot attribute data) for each lot is created as a file for each lot and stored in the storage device 2, and if necessary, the lot attribute data of each lot is extracted and processed. , Production management.

Here, the lot attribute data of each lot managed by the computer is, for example, a movement vote number, a production lot number, a product alias, a product kanji alias, a forced progress stop, a product group code, a production date code, a main material code. , Main material alias, Main material delivery slip number, Production designated month, Process input quantity, Production start date / time, Physical production completion date / time, Standard production completion date / time, Production completion date / time, Final good product quantity, Total number of rejected products, Production It contains a very large number of items such as final adjusted quantity, manufacturing return quantity, total manufacturing process yield forecast, and total manufacturing process yield record.

The computer of the center searches the lot attribute data for all lots put into the manufacturing line according to the contents of management to be executed, extracts data of necessary items according to the contents of management from the lot attribute data, and extracts the extracted data. The data is processed to achieve the desired management.

[0007]

When it is desired to know the progress status of the production work of the entire production system, the amount of lots input / output of each manufacturing process (hence, the number of lots staying in the manufacturing process), each manufacturing process Most of the progress status can be grasped if there is information such as the individual number of the lot existing in (1) and the number of the manufacturing process in which each lot currently exists.

However, in the conventional management method, even when it is desired to manage only the progress status, the computer of the center searches all the items of the lot attribute data for all lots and extracts only the necessary data from them. Data is processed and the progress is grasped. In this way, when performing progress management, the processing load is extremely high because the center computer must retrieve all lot attribute data relating to all lots, although the data items required for it are limited. It will become big.

In particular, the progress of the production work can be grasped in real time in order to advance the production plan without delay, unlike the case where it is necessary to collectively output the processing results at a later date such as the production yield and the cause of rejected products. Since it is required, it is necessary to reduce the processing load on the computer for progress management and to process it quickly.

The present invention has been made in view of the above problems, and an object of the present invention is to significantly reduce the processing load of a computer required for progress management.

Embodiments of the present invention will be described below with reference to the drawings. The schematic configuration of the production control system used in this embodiment is similar to that shown in FIG. FIG. 2 shows a storage structure of data stored in the information storage device 2 in the embodiment of the present invention. As shown, the storage area a is a storage area,
Three areas b and c are set.

In the storage area a, cumulative information A for each manufacturing process, that is, for each manufacturing process (using the manufacturing process number as an index), a work-in-process product (the processing in progress here) that originally existed in the manufacturing process. Of the lot), that is, the total amount of initial work-in-progress, the cumulative amount of input of the lot (input cumulative amount) and the cumulative amount of delivery (output cumulative amount) to the manufacturing process over time. Therefore, based on these pieces of information, it is possible to know how many lots currently exist as work-in-process in each manufacturing process.

In the storage area b, the status information B of each manufacturing process, that is, for each manufacturing process (using the manufacturing process number as an index), which number lot is present as a work in process at that manufacturing process. The individual number data of the lot for indicating whether or not it is stored.

In the storage area c, individual status information C of each lot, that is, for each lot (using the lot number as an index), information on which manufacturing process the lot is currently in, and as described above. Various lot attribute data is stored. Also, in the case where a lot is partly divided in a manufacturing process and is postponed to the next manufacturing process, and then the remaining part of the lot is chased and integrated again in one of the later manufacturing processes, Information regarding the division / integration (lot discrimination, time, quantity, etc.) is also stored for each lot.

[0020] Computer 1 of the center in the embodiment system in Fig. 3 the steps of storing data collected from the data terminal 4 ₁ to 4 _M to the storage device 2 is shown. When the data is input to the computer 1 (step S
1) Immediately after the input, the data is identified and it is discriminated which one of the cumulative information A for each manufacturing process, the status information B of each manufacturing process, and the individual status information C of the lot is applicable (step S2). ), The contents of the storage areas a, b, and c of the storage device 2 are updated according to the classification result (step S
3 to S5).

As described above, by dividing the data storage area in the storage device 2, even when the computer wants to grasp the progress status, only the data necessary for the progress can be obtained quickly and accurately, and all the data can be obtained. The processing load is greatly reduced compared to the conventional method of searching.

For example, when it is desired to manage the progress of the production work by paying attention to the "quantity" of the processed lot, the computer 1 accesses only the storage area a of the storage device 2 to obtain necessary data (cumulative data). The information A) may be acquired. By referring to the cumulative information A, it is possible to know what amount the lot of the processing material is processed in each manufacturing process (not individually discriminating each lot) for the entire production line. Further, it is possible to easily grasp a manufacturing process in which the amount of work in progress has increased or a manufacturing process in which work is available at present. Therefore, appropriate production control can be carried out based on these pieces of information.

Further, for example, when it is desired to manage the progress of the production work by paying attention to the time when the lot passes through each manufacturing process, the storage area b of the storage device 2 is accessed to obtain the status information of each manufacturing process. B should be acquired. By referring to this status information B, it is possible to know what kind of lot exists in each manufacturing process at the present time by individualizing each lot by the lot number, and based on the working time of each lot. Production control can be implemented.

Further, when it is desired to manage the progress status in detail by focusing on each lot, the storage area c of the storage device 2 may be accessed to acquire the individual status information C of the lot.
Referring to the individual situation information C, which manufacturing process the lot of interest exists at present, history of the lot (information such as which manufacturing process comes to which manufacturing process), and the like You can know the detailed contents of
Appropriate production control can be implemented based on it.

Further, the individual situation information C in the above-mentioned storage area c
Apart from the above, information about which manufacturing process the lot currently exists for each lot may be stored in another independent storage area.

The management information can be displayed on the image display device 3 as necessary to notify the maintenance person. Alternatively, the computer 1 may automatically perform the processing based on the management information without displaying the image.

Various modifications are possible in carrying out the present invention. For example, in the above-described embodiment, the case where the progress management method of the present invention is applied to the production system in the manufacturing industry has been described, but the present invention is not limited to this, and for example, a logistics management system in the transportation industry,
Alternatively, the present invention can be applied to an ordering management system in a wholesale / retail industry. In other words, in the physical distribution management system, the process from the delivery order of the package to the arrival at the addressee is divided into a plurality of processes, and the progress of the delivery of the package is managed for each process. Further, in the ordering management system, the process of the ordered products flowing from the producer to the wholesaler to the retailer is divided into, for example, a plurality of stages from when the order slip is issued, and the progress is managed.

[0028]

As described above, according to the present invention, the processing load of the computer required for the progress management can be greatly reduced, and the progress of work can be performed in real time without imposing a heavy load on the computer. It becomes possible to grasp.
