Abstract: A class of Petri nets, called extended Petri nets, with multiple types of places, multiple classes of tokens and multiple arcs is proposed. It is utilized for the hierarchical modeling of flexible manufacturing systems, ensuring a priori that the extended Petri net system model obtained is error free. The proposed method views the operation of the flexible manufacturing system as a process that is decomposed into operations with specified precedence relations. The extended Petri net system model is synthesized from the component nets. A software package has been developed to simulate the execution of the model obtained.
Keywords: hierarchical modeling analysis (and) simulation; flexible manufacturing system; extended net; precedence relation; simulation software package.
