A Heuristic Scheduling Policy for Multi-Item, Multi-Machine Production Systems with Time-Varying, Stochastic Demands
针对多品种多机器生产系统在随机时变需求下的调度问题,将动态周期长度启发式与非线性整数优化结合,提出一种分配产品到机器并安排产量的策略,仿真测试表现良好。
An effective scheduling policy known as the Dynamic Cycle Lengths Heuristic was introduced by Leachman and Gascon in 1988 for the multi-item, single-machine production system facing stochastic, time-varying demands. In this article we develop a heuristic scheduling policy for the multi-machine extension of the same problem. We integrate the concepts of the Dynamic Cycle Lengths Heuristic with a nonlinear integer optimization model to obtain an overall scheduling policy that allocates items to machines and schedules production quantities during the next time period. We report promising performance in limited simulation tests of the policy.
