避免FMS死锁的控制策略

Deadlock Avoidance Policies for a Class of FMS's

本文利用ＦＭＳ的Ｐｅｔｒｉ网模型讨论系统的死锁问题．给出了系统死锁的必要充分条件，提出了避免系统死锁的反馈控制策略．这种策略对系统的限制小，在许多情形下是最优的．

This paper discusses the deadlock problems in FMS,s by using its Petri net model. The necessary and sufficient conditions of system deadlock are characterized. We presented a deadlock avoidance feedback policy. This policy allows the maximal use of resources to optimize the through put of the FMS in many cases.
