The Scheduling of Multiproduct Singlestage Batch Plants under Uncertainty

In this paper,the multiproduct singlestage batch plants under uncertainty are discussed,and the scheduling model with uncertain processing time as well as sequence-dependent setup-time is established based on the fuzzy theory.By using the algorithm of maximizing the membership function of middle value,the fuzzy model is then transformed into deterministic model,and an effective genetic algorithm has presented to minize the makespan.The simulation results have shown the efficiency of the proposed model and algorithm.
