Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production management system in the steel industry, and more particularly to a production management system capable of setting a delivery date in response to a normal order and particularly an order additionally or urgently requested by a user.

[0002]

2. Description of the Related Art As is well known, in the steel industry, FIG.
The product is manufactured through the steps shown in FIG. First, sinter ore in which iron ore and limestone are sintered and coke in which coal is carbonized are charged into a blast furnace, and reduced and melted by hot air in the blast furnace to obtain pig iron. The obtained pig iron is subjected to a pretreatment to remove impurities such as silicon, and is then sent to a converter where oxygen is blown into the pig iron to adjust the composition of the steel. The steel obtained in the converter and refined is sent to the continuous casting process to make slabs and blooms. After that, heating and rolling (hot rolling) in the continuous hot rolling process for each slab created
The treatment is performed to obtain a hot rolled steel sheet. The obtained hot-rolled steel sheet is directly used as a product, or is sent to processes such as cold-rolling and plating according to demand to be subjected to these treatments.

By the way, when a product is manufactured through the above-mentioned various processes, the required process differs depending on the demand of each product. For example, products that are completely manufactured by hot rolling, products that are manufactured only by cold rolling after that, products that are manufactured only by plating,
There are products manufactured by both cold rolling and plating. In this way, various products must be manufactured on demand. Therefore, in terms of production planning, it is important for production efficiency to collectively manufacture products that pass through the same process. However, since various orders from users have different delivery dates, products that pass through the same process are grouped according to these delivery dates, a production plan is set, and production processes are managed.

[0004]

Conventionally, in such production control, when there is an order from the user, a production plan is created in consideration of the delivery date for each contract number unit that has been ordered, and billing for steel or work The instructions were being given. Therefore, when a user suddenly requests a request for early delivery, in order to respond to the delivery date of this order, we urgently instruct the work, change the material and change the production unit and adjust the delivery date. Had to do.

Therefore, not only the materials and schedules for other products are affected, but also the work of adjusting the delivery date becomes complicated, and there is a possibility that troubles such as delivery delay and shipment of different materials may occur.

In view of the above problems, the present invention sets a delivery date for a normal order, and resets the delivery date when an additional or urgent order is placed, thereby efficiently producing a production plan. The purpose is to provide a production management system for setting up.

[0007]

The production management system of the present invention, as shown in FIG. 1, is a data input section 12 to which order data is input, and an order management for storing order data input from the data input section 12. Order data for each contract stored in the database 14 and the order management database 14,
A product progress database 28 stored as product unit data included therein, a component element database 16 storing order data of the contract unit stored in the order management database 14 as data of the order management number, the order management database 14 and the component elements. Based on the data of the matching unit 18 that performs matching with the database 16, the delivery date information database 20 in which the delivery date is registered based on the order management NO of the component database 16 and the data of the component database 16, the delivery date information database 2 for the customer use schedule

A fixed management delivery date assigning unit 26 that assigns a fixed management delivery date to the product data stored in

[0008] The matching unit 18 compares the order data of the contract unit stored in the order management database 14 with the data of the order management number unit stored in the component database 16 to perform matching, thereby order management. The order data for each contract stored in the database 14 is converted into data for each order management number and stored in the component database 16. The customer use schedule for each order management number stored in the component database 16 is stored in the delivery date information database 2 by the delivery date registration unit 22.
After being stored in 0, the primary management delivery date is assigned to the order data stored in the order management database 14 by the primary management delivery date assigning unit 24, and the product data stored in the product progress database 28 by the fixed management delivery date assigning unit 26. A fixed management delivery date is given to.

[0009]

According to the above-mentioned system of the present invention, the order data is collected into the data of the order management number unit according to the delivery rank, the data of the customer, etc., the primary management delivery date is given, and the final management is performed for each product. Delivery date is given. Therefore, when additional order data is input, it can be managed in units of order management numbers and a delivery date can be appropriately added for each product.

[0010]

Embodiments of the production management system according to the present invention will be described. FIG. 3 shows an example of data stored in the order management database 14. As shown in the figure, the order management database 14 stores each item of the order data input from the data input unit 12. The contract number is a number given to each contract, and Y1 is given in this embodiment. As the representative key items, product type classification, delivery date rank, and representative customer code are stored.
The product category indicates the category of manufactured products, and 1 is given in this example. The delivery date rank is data indicating the degree of approaching the delivery date. The representative customer code is the code of the customer, that is, the orderer.

The serial number component stores the size, weight, and standard of the product to be produced. As the child number component, the orderer, the delivery place, the destination country, etc. are recorded.

FIG. 4 shows an example of data stored in the component database 16. The component database 16 stores data to which an order management number is added based on the data stored in the order management database 14. As shown in the figure, the order management number is
The contract number, that is, a common contract number is given in consideration of the product type and delivery date produced for each order unit.

FIG. 5 shows an example of delivery date assignment performed by the delivery date registration unit 22. That is, a delivery date is given in units of order management number or contract number in consideration of the product usage schedule, and data as shown in FIG. 6 is registered in the delivery date information database 20. In the delivery date assignment shown in FIG. 5, the usage schedule and embedding status of the product with the order management number TM1 are shown for each month and season. For example, 9
The planned use in October of October is 24 tons on the 7th in the beginning, 24 tons on the 12th in the middle, 24 tons on the 15th and 24 tons on the 20th
Tons, 24 tons on the last 23 days. Similarly, the usage schedule for November 1990 is also input.

The planned use data input in this manner is used as data shown in FIG.
Stored in 0.

FIG. 7 shows an example of primary mill management delivery date assignment performed by the primary management delivery date assignment unit 24.
Here, the primary mill management delivery date is given to each contract number. In this example, the contract numbers Y1, Y2, Y3. ． ． A primary mill delivery date is given for each. That is, the first delivery date is assigned in units of order management numbers, which are collections of contract numbers with the same conditions such as product type, delivery date rank, and customer. For example, when the orderer gives an internal notification about the delivery date of the product to be delivered in the next two months, the primary mill delivery date is given based on the delivery date.

In this example, for the contract numbers Y1 to Y6 included in the order management number TM1, the primary mill delivery date is set based on the embedding status of each input amount. For example, if the input amount of contract number Y1 is 60 tons, 24 tons is 1
On October 7, 24 tons will be embedded on October 12, and 12 tons will be embedded on October 15, so October 7 will be set as the delivery date for the primary mill. Similarly, for other contract numbers, the delivery date of the primary mill is set based on the embedding status.

FIG. 8 shows an example of the fixed mill delivery date assignment performed by the fixed management delivery date assignment unit 26. Here, a fixed mill delivery date is given to each individual product. That is, in this example, the additional number 01 included in the contract number Y1
A fixed mill delivery date is given to each product such as ~ 06.
The fixed mill delivery date is given, for example, when the orderer gives a fixed instruction regarding the delivery date of the product to be delivered in the next month, the delivery date is given based on the instruction.

In this example, the order management number TM1 includes products with contract numbers Y1 and Y2, and the products with contract number Y1 are added with 01 to 06 as additional numbers 6
Includes individual products. In this example, each of the products 01 to 06 has a weight of 10 tons. An accounting management date is set for each of these products, and based on this, a fixed mill management delivery date as shown in the figure is set from the embedding status.

FIG. 9 shows a flowchart for assigning an order management number. First, a product to be processed is extracted as an order receiving process based on the data input from the data input unit 12 (step 101). Predetermined data is stored in the order management database 14 (step 102), the data stored in the component database 16 is retrieved based on this data, and it is checked whether or not there is the same data (step 103). Items such as product type, delivery date, and representative user are checked, and if the same data exists, all the data in the component database 16 are expanded. (Step 104). That is, all the tables of the representative key item of the order management number, the serial number constituent element, and the child number constituent element described above are expanded.

In step 103, based on the contract number for which the order has been processed, when all the component data have been expanded, it is determined whether the search key such as the representative key item is the same as the previously processed data. (Step 105). If the key is the same as the last time, step 1
Proceeding to 06, the items for matching the data to be ordered and the data stored in the component database 16 are set, and the matching process is performed (step 10).
6). That is, the serial number component and the child number component of the order management database 14 are checked. First, the data of the serial number constituent element is checked (step 107), and then the data of the child number constituent element is checked (step 108). If the data to be received as an order, that is, the data for each contract number does not match the data in the component database 16, the order management number table in the component database 16 is added (step 109). That is, the data of the contract number to be processed is added to the order management number not registered in the constituent element database 16 and having the common key item. For example, new contract number Yn
If the data processed in (1) is not registered in the component database 16, the order management number TM1 is newly set, and the data of the contract number Yn is registered as the data of the order management number TM1.

If the search key is different from the previous key in step 105, it cannot be compared with the already registered order management number, and therefore a process for assigning a new order management number is performed. In step 110, it is determined whether or not there is data in the internal table of the order management NO. If there is no data, the table is initialized and the already registered internal table data is deleted (step 111). If there is data, it is judged whether or not the order management number is new (step 11).
2). If the order management number is new, the serial number constituent elements to be added to the table of the constituent element database 16 are searched (step 113), the child number constituent elements are searched (step 114), and these are searched.
6 is registered in the table (step 115).

FIG. 10 shows a flow for assigning the primary management delivery date. The data stored in the order management database 14 is retrieved (step 120), and it is determined whether the delivery date is A rank (step 121). If the rank is A, the accounting management date is not required at this point. (Step 122). If it is not A rank, the accounting management date of the fixed management delivery date is obtained (step 123), and it is determined whether or not it is land transportation to the country (step 124). In the case of land transportation to countries other than A rank, since the delivery date is not managed by the order management number, the data corresponding to the contract number is updated (step 125). If it is not domestic land transportation,
Pass the data to the shipping date assignment process (step 12)
6).

After the data stored in the order management database 14 is retrieved in step 120 for the A rank material,
As described above, matching is performed with the data in the delivery date information database 20 (step 127), and it is determined whether or not there is data in the delivery date information database 20 (step 12).
9) If there is any, edit the data in the delivery date information database 20 and obtain the primary delivery date management date as described above (step 130). It is judged whether or not the order management numbers of the order data are the same (step 131), and if they are the same, the last minute order management database 14 is updated (step 132). If they are not the same, the delivery date information database 20 is updated (step 133). Step 12
If there is no data in the delivery date information database 20 in 9, the data is added to the delivery date information database 20 (step 134), the accounting management date of the fixed management delivery date is calculated (step 135), and the data according to the order management number is obtained. Is updated (step 136).

FIG. 11 shows a flow for giving a fixed management delivery date. Data is retrieved from the delivery date information database 20 (step 140), and it is determined whether there is a promised delivery date based on the contract number (step 141). If there is a promised delivery date, the production progress data of the product is taken out based on the delivery date management as shown in FIG. 7 (step 14).
2) It is determined whether or not the product is in the numbered state, that is, whether or not it is a product (step 143). If it is a product, check the product progress shown in FIG. 8 (step 14
4) It is determined whether the product has been shipped (step 145).
If the product has been shipped, the process returns to step 142. If the product has not been shipped, the data shown in FIG. 8 is updated (step 1
46) and returns to step 142.

After taking out the production progress data of the product in step 142, the table data is sorted based on the progress situation of the order data (step 147). next,
Data for each product is embedded by the contract number, that is, a fixed delivery date is added (step 148). After that, the delivery date information data is updated (step 150).

If there is no contractual delivery date in step 141, the process based on the order management number is performed in the same manner as in steps 142 to 150 (step 151).

According to this system, the primary management delivery date and the fixed management delivery date are given as described above, and the production control is performed. Therefore, the order data is grouped into data in order management number units according to data such as delivery rank and customers, primary management delivery dates are given, and fixed management delivery dates are given in product units. Therefore, when additional order data is input, it can be managed in units of order management numbers and a delivery date can be appropriately added for each product.
