The agent technology is combined with petri net in order to enhance flexibility and extendibility, and the agent-oriented single token and colored transition petri net is proposed. Some characteristics such as liveness, fairness and safety are analyzed. Finally, an example in mould agile manufacturing is given to illustrate the use of it.展开更多

To investigate the dynamic properties of LPNs directly, a new method for analyzing LPNs is proposed based on marking reachability graphs in this paper. Enabled conditions of transitions are obtained and a marking reachability graph is constructed. All reach- able markings can be obtained based on the graph; the fairness and reversibility of LPNs are analyzed. Moreover, the computing complexity of the enabled conditions and reachable markings can be reduced by this method. The advantages of the proposed method are illustrated by examples and analysis.展开更多
