DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delivery management system for a coil-shaped product which can be used as a material for individual components by cutting to a specific size.

[0002]

2. Description of the Related Art In the steel industry, paper industry and textile industry, coiled products which can be used as materials for individual parts are manufactured by cutting to a specific length.

[0003] Regarding the production of coiled products in the steel industry, for example, when orders are received collectively at the head office from customers and trading companies, the contents of each order for a plurality of steelworks, for example, In addition to giving a series of manufacturing instructions based on the trading company, quality, contracted quantity, size, etc., from the order receipt to the completion of the production, for example, the required production time of about one month is set. An order-by-order delivery date management method, such as assigning and allocating a due delivery date, is adopted.

In the delivery date management method as described above, delivery date management is performed for each order unit, so that the probability of occurrence of an error is extremely small. However, in this method, a plurality of coiled products with different contract months are managed for each order even if they have the same specification parts of the same customer. It cannot be expected that the improvement in production efficiency that would be brought about by performing the method will be performed.

[0005] Further, the unit of use of the product and the delivery date of the product by the customer are a plurality of production coil units obtained by further subdividing the order unit, and the delivery date is on a daily basis. It is necessary to manage different delivery dates on a daily basis. However, since the production of coiled products is made with the same delivery date to be produced as the delivery date for each order,
Coiled products with a late delivery date within the season will be kept in stock until the designated delivery date.

[0006]

In such a conventional method of managing delivery times in order units, what should be centrally managed as the order of the same specification parts by the same customer is distributed to a plurality of orders, and the production management is performed. And the management of shipments to customers becomes complicated, and production efficiency decreases.

That is, production of a coil-shaped product is performed from a raw material through a plurality of various processing steps. In the manufacturing process of this coiled product, if the production delay occurs in a specific unit coil due to some manufacturing trouble, an express instruction (manufacturing interrupt instruction) of the production of the unit coil must be issued in order to guarantee the delivery date. Disappears. This express instruction leads to a change in the production plan of coiled products after the production interruption, causing confusion in managing the delivery date of other orders,
This lowers the efficiency of production and imposes a large workload on the manager of the manufacturing process.

[0008] Further, since the production plan of the customer often changes in response to changes in market conditions, the delivery date determined at the time of receiving an order for a product in the middle of production is changed. Therefore, it is necessary to make corrections or adjust the amount to be manufactured. However, the production of coiled products is managed on an order-by-order basis as described above. The fact is that it is handled by the labor-intensive work of the manager.

The present invention has been made in view of the circumstances described above, and has been made to enable easy and accurate delivery date management corresponding to a customer's production plan, and to systematize and automate product delivery date management. With the goal.

[0010]

Note that the delivery date / manufactured instruction date and the required order quantity for each production coil, which are the final processing results of the delivery date management system 500, are stored in the production coil management DB 552 and the input arrangement DB 572, respectively.

Next, the contents of the recognition items of the same specification parts are
As shown in FIG. Representative items include, for example, trading companies, customers / factories, varieties, sizes, uses, standards, plating amounts, and the like. In the case of the present embodiment, the delivery date management system 5 described above
Each unit of 00 operates using the recognition items of these same specification parts as keys. In addition, the same type specification parts are, for example,
It can be set for each product type and each customer.Also, the usage plan of the customer can be a production plan for the lower process. Has been explained.

Next, the delivery date management system 50 shown in FIG.
The operation of each unit (function) of 0 will be sequentially described with reference to FIGS. The setting section 510 for setting the appropriate stock period is shown in FIG.
As shown in (1), an appropriate stock period is calculated based on past results for each component of the same kind.

That is, first, in step S1, the contents of the performance management DB 511 in which the past fluctuations of the delivery date of the customer and the fluctuations of the manufacturing completion date for each specification part are stored are read. Next, in step S2, fluctuations in the delivery date and the manufacturing completion date are calculated based on this information, and the subsequent step S2 is executed.
At 3, the appropriate stock period is calculated.

FIG. 7 shows a calculation example of the proper stock period. According to this, first, the variation in the delivery date and the variation in the manufacturing completion date are calculated as shown in (1), and these calculation results are replaced with the delivery date changing days and the manufacturing completion date changing days, respectively. Next, as shown in (1), the number of days of change is obtained by adding the respective number of days of change and the standard number of days of inventory of all parts to determine the number of days of inventory for each specification part. The appropriate number of days of stock is obtained by further adding the number of days resulting from the above. This is the proper stock period.

In this example, the past (July and August
The appropriate stock period of 17 days in September is obtained based on the results of the change of the delivery date of the consumer and the change of the production completion date.
The calculation result of the appropriate stock period for each component of the same kind determined as described above is stored in the appropriate stock period table DB 514 in step S4 in FIG.

The appropriate stock period stored in the appropriate stock period table DB 514 is corrected by a human operation according to, for example, economic trends and other information. That is, as shown in FIG. 6, in step S5, the contents of the appropriate stock period table DB 514 are read, and in subsequent step S6,
By inputting a predetermined correction value, the appropriate stock period calculated as described above is corrected. The corrected appropriate stock period is determined in step S7 by the appropriate stock period table DB5.
14 is stored again. In this example, as shown in FIG. 7, a correction of −3 days is performed on the proper stock period 17 calculated as described above to obtain a proper stock period of 14 days.

The daily development unit 520 of the usage plan of the consumer is:
As shown in FIG. 8, customer information is read for each part of the same type of specification, and daily development calculation is performed.

That is, first, in step S8, the contents of the customer information DB 521 (information such as the distribution stock amount, the mill stock amount, the use plan, and the holiday calendar for each customer stored for each part of the same kind) are read. Consumer usage plans include:
There are two patterns, one in which the usage plan is stored in advance by day and the other in which the monthly usage plan is stored. If the monthly usage plan is stored,
In step S10, a daily development calculation as shown in the example of FIG. 9 is executed using a holiday calendar for each customer. On the other hand, if the daily use plan is stored, the process in step S10 is not performed. In the following step S11, the distribution stock amount, the mill stock amount, and the daily use plan of the customer for each part of the same specification developed as described above are stored in the customer information work DB 523.

The usage plan of the customer can be, for example, weekly, seasonal, or monthly, but the following example describes a case where the plan is developed on a daily basis.

The same part grouping unit 540 of the order
As shown in FIG. 10, the keys of the recognition items of the same specification parts as shown in FIG. 4 are extracted from the order information, and the orders are grouped by the same specification parts by sorting in order of the part keys.

That is, first, in step S12, order information, which is the contents of the order management DB 541, is read, and in step S13, a part key is extracted using the recognition item of the same specification part as a key. Then, the same process is repeated until the extraction of the part key is completed for all the order information stored in the order management DB 541. The order management DB
541, as shown in FIG. 11, the contract month, trading company, customer /
Factory, quality, contract amount, size, application, standard, plating amount,
Items such as the adopted manufacturing method are stored.

If it is determined in step S14 that the extraction of the part keys for all the order information has been completed, the order is sorted in the order of the part keys in the following step S15. The sorted order information is stored in the order information work DB 544 in step S16.

The same component grouping unit 55 of the manufacturing coil
0 is the same part grouping unit 54 of the order as described above.
Using the order information grouped for each component with the same specification by 0, grouping is performed for each of the components with the same specification for a plurality of manufacturing coils that are individually linked to the order.

That is, as shown in FIG. 13, the manufacturing coil management DB 552 uses the manufacturing coil identification number of the manufacturing unit as a unique key to store items such as weight, scheduled date, order number with string, sampled weight, and adopted manufacturing method. It is remembered. On the other hand, the order information work DB 544 is provided with a part key indicating the same kind of specification part, and the orders are sorted in that order. Therefore, as shown in steps S17 to S22 of FIG. Then, information on a plurality of manufacturing coils linked to the order is sequentially extracted from the manufacturing coil management DB 552, and a component key is set.

The manufacturing coil information to which the component keys are assigned in this way is sorted in the order of the component keys in step S23, and in the order of the scheduled accounting date in the same component key, and then the manufacturing coil information work is sorted in step S24. DB555
To be stored.

FIG. 14 shows an example of the contents of the production coil information work DB 555. This example shows a case where one order is tied to one manufacturing coil. However, even when a plurality of orders are tied to one manufacturing coil, if the manufacturing coil is logically divided, Similar processing can be performed.

As shown in FIG. 15, a delivery date / manufacturing instruction date setting unit 560 for a manufacturing coil includes a demand inventory constituted by a distribution inventory quantity, a mill inventory quantity, and a daily use plan of a customer for each part of the same specification. House information, manufacturing coil information grouped by the component key by the same component grouping unit 550 of the manufacturing coil, and sorted in the order of the scheduled accounting date in the same component key, and the appropriateness set by the appropriate stock period setting unit 510 Using the stock period information, the delivery date and manufacturing instruction date for the manufacturing coil are set.

That is, first, in step S25, the contents of the customer information work DB 523 are read for each component of the same kind, and in step S26, the distribution inventory amount, the mill inventory amount, the customer date The distribution inventory and mill inventory are allocated from the separate usage plan to the daily usage plan of the customer.

Then, in step S27, the contents of the manufacturing coil information work DB 555 are read for each component of the same kind, and in step S28, it is determined whether or not there is a target part key. By assigning to the daily usage plan of the house in a left-justified manner,
Determine the delivery date for the production coil. If it is determined in step S28 that there is no target component key,
Returning to step S25, the same processing is performed.

Next, in step S30, after reading the contents of the appropriate stock period table DB 514, the process proceeds to step S3.
In step 1, the production instruction date for the production coil is determined from the delivery date and the proper stock period of the production coil determined as described above by the processing shown in FIG.

The delivery date / manufacturing instruction date for the production coil determined in this way is stored in the production coil management DB 552 in step S32. Further, the daily usage plan amount of the customer for each component of the same specification which has not been compensated by the allocation of the manufacturing coil as described above is calculated in step S33.
Is stored in the customer remaining information work DB 568. In the example shown in FIGS. 16 and 17, for example, the production coil having the production coil number 0001 has a delivery date of September 16
