The Application of Visualized Simulation in Scheduling Re-entrant Manufacturing System

The problem of scheduling re-entrant manufacturing system arises with the development of semiconductor industry. The optimization of the scheduling problem of re-entrant manufacturing system is very difficult. Visualized simulation based scheduling is well-thought-of due to the knowability of the simulation process. We developed a visualized simulation based scheduling system for re-entrant manufacturing system in this paper. The system describes the attribute of re-entrant expressly by using virtual devices and helps to improve the scheduling strategy effectively.
