Abstract: 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.

Key words: Petri nets, decision making, expert systems
