An improvement to the dynamic cycle lengths heuristic for scheduling the multi-item, single-machine

A heuristic scheduling policy for multi-item, single-machine scheduling system facing stochastic, time-varying demands was previously introduced by Leachman and Gascon. In this technical note the authors 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%.
