Abstract

This paper considers an industrial scheduling problem. It involves total cost minimization and the determination of the optimal spinpacks replacing cycle time, while meeting the minimum demands for the several products. The study is carried on integrated optimization for the decision of the spinpacks cyclic replacing and the production scheduling of multi-product. A mixed integer linear program (MILP) is presented. The objective function includes the product changeover cost, spinpacks cyclic replacing cost and etc. The resulting MILP can be solved to optimality within reasonable computational time. The effectiveness of the proposed model and methods are verified with the data collected from a real-world manufacturing facility.
