Multi-Product Production Scheduling in Automated Continuous Processes

抄録

In the multi-product production of coating and heat treatment, various kinds of jigs and fixtures are used exclusively for each product. As the daily fluctuation of delivery requirements is large, either the number of jigs and fixtures maintained or the amount of inventories, has to be kept large. Therefore, in the scheduling, the trade-off between them has to be taken into account. This type of the multi-product scheduling is called here the multi-product production scheduling in the automated continuous process. The paper formulates this type of the scheduling problem mathematically and presents a mixed integer programming ;model. An example involving 8 products and 9 days is numerically solved. The optimal solution and its dynamic characteristics are discussed.
