Material balance model and scheduling algorithm of cold rolling production line

Considering a great number of manufacturing units and a diversity of product categories in cold rolling production line, a total cost objective function is established in this paper which is on the basis of satisfying the demand of customer orders and controlling inventory within a reasonable range. To obtain a better solution, a class of correlative genetic algorithm is used to solve such function. For verifying the effectiveness of the proposed solution, the real practical production data from the cold mill of Shanghai Baosteel Co., Ltd are adopted to simulate during which this proposed model and algorithm shows that the good results can be achieved.
