روش جستجوی اکتشافی ترکیبی برای برنامه ریزی بدون وقفه سیستم های تولید انعطاف پذیر با استفاده از شبکه های پتری

Based on the Petri net models of flexible manufacturing systems, this paper focuses on deadlock-free scheduling problem with the objective of minimizing the makespan. To avoid deadlocks, the deadlock control policy is embedded into heuristic search strategies, and two hybrid heuristic search algorithms for deadlock-free scheduling of FMSs are proposed.
