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 proposed an interdivisional scheduling method which integrates two parts, interdivisional scheduling part using Lagrangian decomposition coordination method and divisional scheduling part using real-time scheduling and simulation method, and a co-operation mechanism of these two parts. To clarify the validity of the proposed method, experimental model of Interdivisional Scheduling System is developed and numerical experiments are executed. With this method, we can obtain an effective schedule continuously across all divisions which can respond flexibly to both long and short term fluctuation of the manufacturing environment.
