212 A Study on Integration of Interdivisional Scheduling in Dynamically Changing Manufacturing Environment : Cooperation of Divisional and Interdivisional Scheduling

Abstract

In dynamically changing manufacturing environment, it is quite difficult to optimize interdivisional scheduling which reduces total manufacturing cost of all divisions in a factory following fluctuations in demand. To solve this problem, we developed an integrated interdivisional scheduling system which consists of interdivisional scheduling part using Lagrangian decomposition coordination method and divisional scheduling part using real-time scheduling and simulation method so that an effective schedule across all divisions can be obtained continuously under the flucturating manufacturing environment.
