Note: An Improvement to the Dynamic Cycle Lengths Heuristic for Scheduling the Multi-Item, Single-Machine
改进了Leachman和Gascon提出的多品种单机调度启发式策略的计算方法，模拟测试表明改进版在保持或提升客户服务水平的同时，将总库存和设置成本降低1-7%。
A heuristic scheduling policy for multi-item, single-machine scheduling systems facing stochastic, time-varying demands was previously introduced by Leachman and Gascon. In this technical note we provide an improvement to the calculations of the policy. Simulation tests of the revised version of the policy indicate that the improvements maintain or enhance customer service while reducing total inventory and setup costs on the order of 1–7%.
