DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production management technique for parts such as a piston, a piston ring, a cylinder block, and a valve which are necessary for producing, for example, an engine product. First, a production system in which the present invention is effectively used will be clarified. (1) Multiple parts production lines or production processes are used to produce parts. For example, cylinder blocks are produced on a cylinder block production line, and valves are produced on a valve production line. Here, each component production line may be located not only in the same factory but also in separate factories. The term “production line” used here means not only a physically existing production line but also a process of producing parts. (2) Several types of parts are produced on the parts production line. For example, one valve production line produces a plurality of types of valves having different diameters. However, it is not necessary to produce a plurality of types of parts on all the parts production lines, and this does not prevent a part production line that produces only one kind of parts.

(3) There are also a plurality of product production lines. For example, a 4-cylinder engine in a specific product production line,
Six cylinder engines are produced on other product production lines. (4) The product production line produces multiple types of products. For example, on a production line for a four-cylinder engine, an engine with a turbo and an engine without a turbo are produced. However, there is no need to produce multiple types of products on all product production lines,
It does not prevent that there is a product production line that produces only one kind. (5) Parts produced on a specific part production line may be supplied to multiple product production lines. For example, a valve produced in a valve production process or a production line is supplied to a production line for a four-cylinder engine and also supplied to a production line for a six-cylinder engine. Note that, in the above example, the case where the engine is a product is illustrated, but when the product is a vehicle, the engine, the vehicle body, the frame, and the like are parts. That is, what is a product at one stage may be a part at the next stage. The present invention is beneficial at each stage.

[0003]

2. Description of the Related Art As products become more complex and the number of parts increases, it becomes difficult to grasp which parts and how many parts need to be produced in order to produce a product. The tendency for product types to increase increases this difficulty. It is of course conceivable to use a computer for this purpose. Therefore, a technique that enables the above analysis with a storage capacity as small as possible is disclosed in Japanese Patent Application Laid-Open No. 1-112364. With this technology, necessary parts and their quantities are calculated by specifying a product and inputting its production quantity.

[0004]

However, for example, if a large production system with 250 parts production lines, 85 product production lines, 15,000 kinds of parts and 5,000 kinds of products is required, Even if the number of parts is calculated, it is not easy to know which part production line will produce it. In particular, it is extremely difficult to grasp which parts and how many parts need to be produced for each part production line. For this reason, it is extremely difficult to control the production of each part production line.

When trying to calculate the parts and the required quantity for each part production line, not only the parts, the products requiring the parts and the number of parts required for the products, but also the parts production line for producing the parts and the product production It is necessary to store the line information as well. However, when the above information is stored by the conventional technology, a huge storage capacity of 180 megabytes is required in the case illustrated above, and a part production line is input, and the parts to be produced on the part production line and the number of parts are calculated. It takes several hours for the process to be performed. Therefore, it cannot be used for practical use. In view of the above, the present invention is to develop an apparatus capable of obtaining information necessary for managing parts by production line, requiring less storage capacity, and shortening search time.

[0006]

To this end, the present invention has developed an apparatus whose concept is schematically shown in FIG. In this apparatus, as schematically shown in FIG. 1, various types of parts (A1, A2, A3...) Are produced on a plurality of parts production lines (B1, B2, B3...), And the parts are used. In a production system in which various types of products (E1, E2, E3,...) Are produced on a plurality of product production lines (F1, F2,. This is a component development processing apparatus that calculates the components to be produced by the and the number thereof.

This parts development processing apparatus includes a product production plan input means I for inputting the number of products produced for each type of product, and a product production information storage for storing the inputted number of products produced in association with the type of product. Means M, a part production line B, a part production line A produced by the part production line, and an arrangement information storage part J for storing a part production line F in which parts produced by the part production line are used in association with each other; In-process information storage means K for storing a product production line F and a product E produced in the product production line in association with each other, a product E, parts A required for production of the product, and It has an allocation information storage means L for storing the required number of parts in association with each other, a means H for specifying a part production line, and a part production number calculating means N for each part production line.

[0008] Here, the part production number calculating means N for each part production line (1) converts the information stored in the arrangement information storage means J to the part production line B specified by the part production line specifying means H. A corresponding part A and a product production line F are extracted, and (2) a product E corresponding to the product production line F extracted in the above (1) is extracted from the information stored in the in-process information storage means K. (3) From the information stored in the allocation information storage means L, the information storing the part A extracted in (1) and the product E extracted in (2) in association with each other. (4) From the information stored in the product production information storage means M, extract the number of products corresponding to the product E extracted in (3), and (5) extract in (3) Part A
Each time, by summing the number obtained by multiplying the number of parts extracted in the above (3) and the number of productions extracted in the above (4), the number of parts in the part production line B specified by the part production line specifying means H is calculated. The part A to be produced and the number thereof are calculated.

[0009]

Next, as illustrated in FIG. 2, parts A1 and A2 on the parts production line B1, parts A3 on the parts production line B2, products E1, E2 and E3 on the product production line F1.
However, the product E4 is produced on the product production line F2, the product E1 includes the components A1 and A2, and the product E2 includes the component A.
2 and A3, product E3 is part A3, product E4 is part A
The operation of the present invention will now be described by taking as an example the case where components are supplied from the component production line B1 to the product production lines F1 and F2, and from the component production line B2 to the product production line F1. It should be noted that this is merely an example for explanation, and the present invention is not limited to the example.

Here, first, the arrangement information storage means J stores the parts A1,
A2 and production lines F1 and F2 to which parts produced on the part production line B1 are supplied are stored. In addition, information on the parts production line B2 is also stored.

When a part production line (here, B1 is specified) is specified by the part production line specifying means H, the part production line-by-part production number calculating means N first stores it in the arrangement information storage means J. The retrieved information is retrieved, and the corresponding part (in this case, A1 and A2) and the corresponding product production line (in this case, F1 and F2) are extracted. The information extracted in FIG. 2 is marked with a circle.

Next, the in-process information is searched, and the products (E1 to E4 in this case) produced on the previously extracted product production lines F1 and F2 are extracted. Next, the allocation information is searched,
Parts (A1, A2) and products (E1 to E) extracted earlier
The information stored in association with 4) is extracted. In the case of FIG. 2, information (records) marked with * on the right side of the allocation information is extracted.

Next, the product production information is searched, and the number of products (E1 to G4 in this case) of the products (E1 to E4) extracted earlier is retrieved.
4) is extracted. Finally, for each of the parts (A1, A2) extracted earlier, the number of parts required per product (for example, part A1 is C1 for product E1, C6 for product E4, product A2 is It is illustrated that C2 pieces are required for the product E1 and C3 pieces are needed for the product E2), and the number of products produced (G1 to G4) is multiplied.

The parts (in this case, A1, A) produced on the specified parts production line (in this case, B1)
2) and the production number of each part (in this case, the part A1 is C
1 × G1 + C6 × G4, A2 is C2 × G1 + C3 × G
2) is calculated. In this way, according to the apparatus of the present invention, by specifying a part production line, the parts to be produced on the part production line and the number of parts to be produced are calculated.

Here, since the information is distributed among the arrangement information, the work-in-progress information, and the allocation information, the retrieval time is remarkably shortened, and the unnecessary data is deleted, so that the storage capacity is remarkably reduced. For example, in the case illustrated above, the required storage capacity is reduced to about 1/20, and the search time is reduced to 1/2.
000.

[0016]

An embodiment of the present invention will be described below. FIG. 3 shows a system configuration of a component development processing apparatus according to the present embodiment, which includes a console 2 having a keyboard and a display, an external auxiliary storage device 4, a data processing device 6, an internal auxiliary storage device 8, and a communication control device 10. , A floppy disk drive 12.

From the console 2, an operator can input a part production line. Also, this component development processing device is connected to a product production management computer via a communication control device 10, and information indicating which products and how many products are to be produced within a predetermined period is transmitted from the communication control device 10. It is configured to be input to the component development processing device.
In this embodiment, the communication control device 10 constitutes a product production plan input means I.

The input product production information is stored in a product production information file in the external auxiliary storage device 4. In the external auxiliary storage device 4, there are other arrangement information files, work-in-progress information files, allocation information files, and parts production line-specific information files.

In the arrangement information file, for each code of the part production line, the code of the part produced on the part production line is associated with the code of the product production line on which the part produced on the part production line is used. It is stored and remembered. The in-process information file stores, for each code of the product production line, the code of the product produced on the product production line in association with each other. In the allocation information file, for each product code, a code of a part required for production of the product and a number of parts required for one product are associated, that is, the above three types of information are stored in one. Is stored as one record.

The internal storage device 8 stores a program for executing the processing of FIG. The processing of FIG. 4 is programmed to be executed for every part production line. That is, a program for sequentially specifying the component production line is stored in the internal auxiliary storage device 8, and a new component production line is specified each time the processing in FIG. 4 is restarted. The program for sequentially specifying the parts production line corresponds to the parts production line specifying means in the present embodiment.

Now, for example, assume that the parts production line B1 in FIG. 2 is specified. Then, using the parts production line (B1) specified in step S2 of FIG. 4 as a search key, the arrangement information file is searched, and the codes (A1, A2) of the parts produced on the parts production line and the parts are used. The code (F1, F2) of the product production line is extracted. Here, the order information file is stored in a state of being sorted for each part production line for easy retrieval.

Next, in step S4, a work-in-progress information file is searched using the product production line extracted in step S2 as a search key, and products produced in the product production line are extracted. In this case, information is stored in the in-process information file in a state of being sorted for each product production line in order to facilitate the search. Next, in step S6, the allocation information file is searched, and the component extracted in step S2 is
A record storing the product extracted in step S4 in association with the product is extracted, and a number indicating how many parts are required for each product is extracted.

Next, the product production information file is searched using the product included in the record extracted in step S6 as a search key, and the production number of the product is extracted. Then, in step S10, for each product in which the part is used, the number obtained by multiplying the production number of the product by the number of parts per piece is obtained, and the total is calculated to calculate the required number of parts.

In step S12, the calculated parts and the number of parts are stored and stored in a storage location for the part production line in the part production line-specific information file. As a result, as shown at the bottom of FIG. 2, the parts (A1, A2) produced by the part production line and the number of parts are stored in association with the part production line of B1.

By performing the above-described processing on all the parts production lines, the parts to be produced on each part production line and the quantity are stored in association with each other. Then, by inputting the part production line code from the console 2, the operator can know the parts and the number of parts required to be produced on the part production line based on the contents of the part production line-specific information file. The production management of the parts production line is significantly facilitated.

In the above embodiment, the processing shown in FIG. 4 is executed in advance for all the component production lines, and the execution result is stored in the information file for each component production line. Instead, the process of FIG. 4 may be executed on a parts production line specified by the operator using the console 2. Even in this case, the parts and the quantities that need to be produced in a specific parts production line are calculated based on the number of products produced. As is apparent from the above description, in this embodiment, the program for performing the processing of FIG. 4 and the computer involved in the execution of the program constitute the part production number calculating means N for each part production line.

[0027]

According to the present invention, the relationship between parts-parts production line-number of parts-product-product production line is stored separately in arrangement information, work-in-progress information and allocation information, so that the retrieval speed is improved. Thus, the required storage capacity can be reduced. For this reason, information indicating which parts need to be produced on which part production line can be easily extracted and calculated from the information on the required number of products to be produced, and the production management of the parts production line is significantly simplified. You.
