Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for responding to a delivery date of a production product for performing a delivery date response to an ordered product in planned product production (hereinafter referred to as an expected production system as appropriate), and an information recording medium.

[0002]

2. Description of the Related Art Conventionally, a delivery date response for an order product in a make-to-stock production system in a plant of this kind is made in consideration of a product inventory for this product planned production, a work-in-progress product, and an order shipment for a product on a production plan. Is going. That is, the product inventory for the order, the work-in-progress product, and the status of the product on the production plan are continuously grasped (denoted as “link” as appropriate).
Then, the delivery date is answered.

[0003] When a delivery date is answered for an ordered product of such a product planned production, it is necessary to change the production plan data of all the manufacturing processes according to the delivery date response. This is based on the production plan data of the final product to be shipped (the so-called finished product or semi-finished product consisting of one or more products, which is the product to be shipped obtained in the final manufacturing process). Because the delivery date is implemented by linking,
This is because it is necessary to change the production plan itself for all the manufacturing processes in order to cope with the fluctuation of the production plan created based on the demand forecast and the actual demand. Therefore,
The manufacturing process grasping process (denoted as operation process as appropriate) for the delivery date reply becomes complicated.

In order product production in such product planned production, since the production plan based on demand forecast and actual demand hardly match, the product is manufactured so that the number of products is slightly larger than the actual demand. Therefore, the inventory of products, in-process products and parts increases.

[0005] A number of proposals have been made for a delivery date response processing method in product planning production involving such a problem. For example, in order to efficiently produce a plurality of new kinds of products, a production plan is made using a computer arithmetic unit, and a production plan is made in accordance with a supply schedule and a consumption schedule of materials (for example, JP-A-5-10
No. 8662, “Production planning device”. In addition, production progress information for each customer in order production in the make-to-stock production method is immediately obtained and grasped (for example, Japanese Patent Application Laid-Open No. 8-25191, "Management of Production Progress of Make-to-Stock Products"). Method and production control device ”).

Further, as a proposal for improvement to the production of an ordered product by the make-to-stock production system, when a production instruction is changed, the order of the parts, a shipping instruction, a production instruction, and a request to a subcontract factory are made for a meeting for the change and a production adjustment in a later manufacturing process. In some cases, confusion caused by communication or the like is converged in a short time (for example,
-64510, "Printed Circuit Board Production Apparatus and Production Planning Method").

[0007] Further, as a proposal for order production by the make-to-stock production system, a production plan including a problem is analyzed, problems are extracted, adjustment contents for improving the plan are narrowed down, etc., and decision-making support in plan adjustment is performed. (For example, Japanese Patent Application Laid-Open No. 9-128440, entitled "Printed Circuit Board Production Apparatus and Production Planning Method"). Further, there is a method in which an accurate delivery date from an order is grasped in a short time to reduce inventory of finished products and materials (for example, Japanese Patent Application Laid-Open No. H10-214293, "Load Assignment Method, Delivery Date Determination Method, Load Assignment"). System, delivery date determination system, production system, recording medium ”).

[0008]

As described above, in the above-described conventional example, the process of ascertaining the manufacturing process becomes complicated when replying to a delivery date for an ordered product of the make-to-stock production system. However, there is a disadvantage that it is difficult to obtain a more accurate delivery date response.

In order-to-order production by the make-to-stock production method, since a production plan based on demand forecast and actual demand are hardly coincident with each other, a large inventory of product inventory, work-in-progress products, and parts is required to maintain inventory. We need to respond to fluctuations. For this reason, there is a drawback that the inventory of products, in-process products, and parts increases.

In the conventional example of the publication, there is room for improvement in the process of grasping the manufacturing process when giving a delivery date response to an order product of such a make-to-stock production system, and for an increase in stock in order product production in product planning production. is there.

The present invention solves such problems in the conventional technology, and the process of grasping the production process (operation process) when replying to the delivery date for the ordered product of the product planned production (prospective production system) is complicated. A more accurate delivery date response can be obtained without the need for conversion, and it is also possible to easily create a production plan and order a part order to the parts supply source, and to reduce the inventory inventory.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, description will be made based on specific embodiments.
The final product S8500-123 to be shipped is May 1
The case where three requests are made every three days will be described as an example. In addition,
The final device S8500-123, as shown in FIG. 3, includes a motherboard S8550-12, a housing S8560-23, and a power supply S8570-34, each of which is a single unit. And the power supply is purchased from the component vendor B and the power supply is purchased from the component vendor C.

First, the table of the data storage unit 3 shown in FIG. 2 (from the part development data 31 to the part determination data 36)
Will be described in detail. FIG. 4 is a diagram for explaining a specific example of the component development data 31 in FIG. In FIG. 4, component development data 31 stores development data for components required when the final product to be shipped is manufactured in the manufacturing process 2 shown in FIG. The expanded data includes child product code and quantity data indicating how many child products are included in the parent product with respect to the parent product code. As shown in FIG. Stored.

FIG. 5 is a diagram for explaining a specific example of the component basic data 32 in FIG. This part basic data 32
In the delivery date response processing form for parts (delivery date response method)
The data for determining is stored. With reference to the component basic data 32, each product executes an allocation processing mode according to the product characteristics.

FIG. 6 is a diagram for explaining a specific example of the production capacity data 33 in FIG. This production capacity data 33
Stores the number of daily productions that can be performed in the manufacturing process 2 in FIG. 3 and the number of customers already determined. This is a delivery date answer processing unit 23a in the delivery date answer unit 23 in FIG.
(Appropriately described as delivery date response method 1).

FIG. 7 is a diagram for explaining a specific example of the parts inventory data 34, the parts supply data 35, and the parts determination data 36 in FIG. 7A shows the parts inventory data 34, FIG. 7B shows the parts supply data 35, and FIG.
(C) shows the part determination data 36. The parts inventory data 34, the parts supply data 35, and the parts determination data 36 include the initial inventory of the product, the consumption amount, which is the number required in the order already determined by the customer for the initial inventory of the product, and the future parts vendor and Data indicating a supply amount, which is a supplyable number from the previous manufacturing process, is stored. The component determination data 36 from the component stock data 34 is used in the processing of the delivery date answer processing unit 23b (denoted as delivery date answer method 2 as appropriate) in FIG.

Next, the processing in the operation will be specifically described. First, when a product code, a required delivery date, and a required quantity are input from the input device 1 in FIG.

The part expanding section 21 searches for the product code S8500-123 of the requested product from the parent product code of the part expanding data 31 in the data storage section 2 shown in FIGS. When the required product code is found in the parent product code, the parent product code is expanded into the child product code by referring to the child product code and the quantity corresponding to the required product code. In the example of FIG. 4, the product code S8500-123 is S8550-
12, S8560-23 and S8570-34, respectively.

Next, the delivery date allocation processing form discriminating section 2 in FIG.
2 executes a process of returning an allocation determination code corresponding to the child product code sent from the component development unit 21. The requested product code is searched from the product code of the component basic data 32, and the allocation determination code is returned. If no search determination code is found, a default determination code is returned.

In the example of FIG. 5, the developed product code S85
The values of “1, 2, 2” are returned to 50-12, S8560-23, and S8570-34, respectively. When the allocation discrimination code is found for the product code, a process corresponding to the allocation discrimination code by the delivery date answering unit 23 shown in FIG. 2 is executed. The data of the product whose discrimination code is “1” is sent to the delivery date response processing unit 23a shown in FIG.
The data of the product whose discrimination code is "2" is the delivery date answer processing unit 2.
3b.

Next, a description will be given of a reserving process for actually calculating the reservable number from the production frame and the stock and returning the result as a delivery date response. The delivery date response processing unit 23a in FIG.
With reference to the production capacity data 33 stored in the data storage unit 3, allocation for parts (delivery date answering method 1) is performed. As the production capacity data 33, a date, a producible number, and a confirmed number are stored for each component, and at the time of allocation, the result obtained by subtracting the confirmed number from the producible number is allocated as an allocatable number.

If it is not possible to allocate the requested date, first, priority is given to shipping in accordance with the customer's delivery date, and the allocation process is executed retroactively from the requested date. . However, if the allocation is made too early, it leads to an increase in the inventory and the leveling of the production is disturbed. Therefore, it is necessary to determine the number of days to go back in advance according to the manufacturing environment. In this example, the number of days that go up is four days. If the allocation is not completed even after the specified number of days,
Allocate after the requested delivery date.

In the present example, three delivery date response requests are sent on May 13 for the code product of S8550-12 (in FIG. 6). When the delivery date reply request is sent, first, a data set of the number of products that can be produced and the determined number of required components from four days before the required delivery date to the required delivery date is read from the production capacity data 33 in FIG. 2 (in FIG. 6). . Then, the available number on the request date is calculated, and if the available number exceeds the requested number, a reply is returned. In this case, the number of requests is 0 for 3 requests, and thus is insufficient. In the case of this shortage, the same processing is performed one day before (May 12).

If the number of requests is less than four days before, the data set on the day after the requested date is obtained from the production capacity data 33 shown in FIG. 2 and the same processing is performed (in FIG. 6). . Here, since only one piece of data can be allocated at the beginning, the data after May 14 is extracted from the production capacity data 33 and the allocation is performed. In the current data example, since there are four available numbers on May 18, the remaining two are allocated on May 18. The assigned result is reflected in the final number.

Next, FIG. 2 in which allocation is performed based on product stocks
The delivery date answering method 2 in the middle delivery date answer processing unit 23b will be described. In the delivery date response method 2 by the delivery date response processing unit 23b, allocation is performed based on the component stock data 34, the component supply data 35, and the component determination data 36 stored in the data storage unit 3 in FIGS.

This allocation (delivery date answering method 2) will be described in detail. FIG. 8 is a diagram for explaining the allocation (delivery date answering method 2 in the delivery date answer processing unit 23b). In the present example, 5 is obtained from the result of the delivery date answer processing unit 23a (delivery date answering method 1)
There is one demand on May 10 and two on May 18. If only the inventory information of the requested delivery date is created and the delivery date is answered, there is a possibility that the product will be out of stock for the subsequent demand. Need to refer to supply data.

Therefore, the delivery date response processing unit 23b
When an allocation request is received, the flow of time is demarcated according to supply information as a start. With reference to the component supply data 35 shown in FIG. 7B, the flow of time is divided at the supply date. In FIG. 8, ~ May 10 (period I), May 11 ~
May 17 (period II), May 18-May 23 (period)
III) It is divided into four from May 24th (period IV).
Evaluation is performed from the last period in which the division was performed. First, the period IV is performed. Since the demand is 5 + 9 = 14 and the supply is 20 pieces, the demand in the period IV only needs to be supplied on May 18.

FIG. 9 is a diagram for explaining the delivery date reply process. In period III, supply is 1 for total 12 demand
0. Therefore, the supply on May 18 alone
Cannot meet demand for III. Thus, there must be room for at least two supplies in the previous period II. This information is saved and the evaluation for Period II is performed. Supply 1 during period II
There are a total of 14 demands with a demand of 0 and a demand of 12 and two demands from period III. As described above, four pieces of demand information are stored for the period I, and the period I is calculated. In period I, the demand is 10 and the demand from period II is 4 pieces, and the initial stock 20 is 20 pieces for a total of 14 pieces. Eventually, period I has six headrooms.

FIG. 9B is a table showing the results, the stock, the available stock, the number of shipments, and the number of demands. Product S8570-34 performs the same processing, and FIG.
It is assumed that the result shown in the table shown in FIG. next,
A process for summarizing the results of all the delivery date responses is performed.

In the present example, one result is returned on May 10 and two results are returned on May 18 for S8550-12. Then, S8560-23 and S8570-34
9 (b) and 9 (c), it is checked whether there is one available stock on May 10 and two available stocks on May 18. Here, both can be allocated and S856
Delivery date of 0-23, S8570-34 is 1 on May 10
There are two on May 18th. Therefore, the delivery date of the final product to be shipped is at the bottom of the table in FIG. The result is sent from the delivery date response processing unit 2 to the input / output device 4 shown in FIG. 1 as a delivery date response for the requested product.

Further, the value of the processing result (table in FIG. 9D) of the delivery date answering part for each part is reflected in the value of the production capacity data 33 of the data storage part 3 and the number of confirmed parts of the part confirmed data 36. .

FIG. 10 is a diagram for describing a production plan and an order plan to a parts vendor. FIGS. 10A and 10B
(C) and (d) show the production capacity data 33 (FIG. 6), the parts inventory data 34 (FIG. 7A), the parts supply data 35 (FIG. 7B), and the parts confirmation data 36 (FIG. 7C). )) Is a table recounted for each part. The table of FIG. 10A is a production plan of the manufacturing process 1 in FIG.
Each table in (c) is for order planning to the parts vendors B and C in FIG.

In the case where the delivery date response is actually implemented, if the delivery date response result is later than the customer requested delivery date, the production quota is increased or the parts supply plan is reviewed,
It is necessary to modify the production plan (FIG. 6) of the manufacturing process 1 in FIG. 3 and the order plan to the parts vendor (FIG. 7B). If the number of available stocks in the tables of FIGS. 10B and 10C is increasing remarkably, the supply plan with the parts vendor is reviewed.
It is necessary to prevent unnecessary work in progress.

Next, another embodiment will be described. At the end of the processing of the data storage unit 3, by performing processing (rollback) to return to the storage state before the storage processing, the contents of the data storage unit 3 are not rewritten by referring only to the result of the delivery date allocation processing. It is possible to As a result, it is possible to always perform the inquiry process for the requested delivery date using the current data, and for the current data,
