Fluctuation smoothing scheduling policies for multiple process flowfabrication plants

摘要

This paper addresses the problem of reducing the mean and varianceof cycle time in large multi-process flow reentrant systems by using amodified version of the Fluctuation Smoothing for Mean Cycle Time(FSMCT) scheduling policy. The plant models used in this paper wereconstructed and distributed by SEMATECH. Three such models are studiedin this paper. The work done in this paper is the first look at thefeasibility of using the FSMCT policy on multi-process flow systems. Thesize and complexities of the models used here limited the number ofsimulations performed in this initial study
