ABSTRACT:
A production management system has processing devices A, B, C, D, E, and P. A kind of product α is processed in the order of the processing devices A, P, B, P, and C, and a kind of product β is processed in the order of the processing devices D, P, E, and P. To determine whether the processing device P is to be used to produce the product α or the product β, an input ratio of each kind of product is multiplied by the number of times of passing the processing device P for each kind of product, thereby calculating a core of each kind of product. Based on the calculated score, whether the processing device P is to be used to produce the product α or the product β is determined. Accordingly, the work-in-process balance of key processes between different kinds of products can be equalized.
