摘　　要：提出一种新的更适合ＦＭＳ（ＦｌｅｘｉｂｌｅＭａｎｕｆａｃｔｕｒｉｎｇＳｙｓｔｅｍｓ柔性制造系统）决策和控制的扩展高级判断Ｐｅｔｒｉ网（ＥＨＬＥＰ－Ｎ），并着重介绍它的建模方法及其在ＦＭＳ决策和控制中的应用。建立基于ＥＨＬＥＰ－Ｎ的ＦＭＳ决策控制专家系统的实践证明，ＥＨＬＥＰ－Ｎ是描述ＦＭＳ的结构、状态和动态行为的有力建模工具。部分成果已经用于航空航天部１５９厂的高级ＤＮＣ系统的设计之中。A new Extended High LeveI Evaluation Petri Net(EHLEP-N)is proposed which is more suitable for FMS(Flexible Manufacturing Systems ) decision and control,and empha-sis is placed on introducing its modelling methods and its application to FMS decision and control.The practice of building up the EHLEP-N-based expert system for FMS decision and control shows that the EHLEP-N is a powerful tool for describing structures,states and dy-namic activities of FMS. Partial results have been applied to designing the advanced direct nu-merical control(DNC)system in the 159th Factory of the Ministry of Aeronautics and Astro-nautics Industry.
