Integrative Cycle Scheduling Approach for a Capacitated Flexible Assembly System*
研究了传统单阶段多品种有产能批量问题，提出集成周期调度方法同时解决批量、产能和排序问题，并用福特工厂数据验证了低成本周期调度方案。
ABSTRACT This study revisits the traditional single stage, multi‐item, capacitated lot‐sizing problem (CLSP) with a new integrative focus on problem structuring. Unlike past research, we develop integrative cycle scheduling approaches which simultaneously address lot‐sizing, capacity, and sequencing issues. Our purposes are to (1) explore the effect of sequencing on inventory levels, (2) examine the problem of infeasibility in the economic lot scheduling problem (ELSP), and (3) provide a simple methodology of generating low‐cost cycle schedules in an environment with discrete shipping, dynamic demands, limited capacity, zero setup cost, and sequence‐independent setup times. Our procedures are compared to benchmark cycle scheduling approaches in terms of both inventory cost and computation time under different demand scenarios, using the operating data from a flexible assembly system (FAS) at the Ford Motor Company's Sandusky, Ohio plant.
