The database 110 stores product number information, bill of material (BOM) information for each product, and similarity rate information of products that can be produced in all manufacturing lines.

At this time, the above-described BOM information is information on the circuit number, material, wire diameter, wire color, length, and applied material. For example, what kind of circuit structure each product has, what material it is formed of, and if the wire is included, the thickness or color , It may be information that comprehensively indicates how long the length is formed, and what material is applied to the product.

In addition, the above-described products that can be produced do not mean only finished products, but include semi-finished products that have completed only some processes, and the above-described part number information may be unique identification information for distinguishing different products.

Meanwhile, the article number information and the BOM information stored in the database 110 may be input in a text format or in a general file format through an input means provided separately.

The similarity rate calculation unit 120 compares the BOM information for each product stored in the database 110 to calculate a similarity rate representing the degree of similarity between products, and matches the calculated similarity rate information with the article number information to a database It performs the function of storing in (110).

At this time, the similarity rate calculation unit 120 calculates the similarity rate for all products stored in the database 110. For example, by extracting two products, the product-specific circuit number, material, wire diameter, The similarity rate of all products can be calculated by comparing the information on the line color, length, and applied materials on a one-to-one basis to calculate the similarity rate by comparing the other two products again.

For example, as shown in Figure 3, the production plan input unit 130, the number of work of the work target product with the product number information '91600-L1170' is 100, the work of the work target product with the product number information '91600-L1180' The quantity may be 150 pieces, and the job quantity of the product to be worked with the article number information '91600-L1250' may be input as 10 pieces.

Then, a manufacturing line to which each product to be processed is to be put and a work order may be allocated by the manufacturing line assignment unit 140 to be described later.

The manufacturing line allocating unit 140 extracts a similarity rate corresponding to the received product number information from the database 110, and based on the extracted similarity rate and the number of work, each manufacturing line and work order to which the target products are to be put Performs the function of assigning.

At this time, the manufacturing line allocating unit 140 assigns the work target product with the largest work quantity among work target products to the production line with the highest priority, and compares the work target product with the work target product with the highest priority to the work target with the highest similarity. Products can be assigned to manufacturing lines with a secondary priority.

For example, as shown in FIG. 4, among the three work target products input to the production plan input unit 130, the work target product '91600-L1180' with the largest work quantity of 150 is assigned to the manufacturing line with the highest priority. The target product '91600-L1250', which has the highest similarity rate of 100% compared to the target product '91600-L1180', is assigned to the manufacturing line with the second priority, and compared with the target product '91600-L1250'. Thus, the product '91600-L1170', the target product with a similarity rate of 93.02%, can be assigned to the manufacturing line with the lowest priority.

That is, the manufacturing line allocating unit 140, after allocating the work target product of the highest priority or the sub-priority priority, the work target product having the highest similarity rate compared to the work target product having the lowest priority next priority. By repeating the processing process assigned to the manufacturing line until the production quantity for each production line is satisfied, the product to be put into operation, the quantity of work, and the order of work can be assigned to each production line.

Therefore, because the product to be worked is allocated according to the number of work and the similarity rate for each production line, the difference in workability for each production line can be reduced and productivity can be improved, and ultimately, operation management efficiency for each production line can be improved. Can be improved.

In addition, since the work quantity and work order are assigned to each production line so that the work methods performed while manufacturing the product to be worked are similar, it is possible to reduce the items that workers of the production line need to know, and to misunderstand or be unfamiliar with the work method. This can reduce the quality defects that occur.
