B35 A Study on Optimization of Interdivisional Scheduling for Dynamically Changing Manufacturing Environment(Advanced machining technology)

Abstract

In dynamically changing manufacturing environment, it is difficult to optimize interdivisional scheduling which reduces total manufacturing cost following fluctuations in demand. To solve this problem, we propose a new interdivisional scheduling method which decomposes the whole problem into process-dependent problems and cooperates between processes using Lagrangean decomposition coordination method and adjusting production lead time. Additionally we examine the effectiveness of this method by numerical experiments.
