| Abstract: | A fuzzy petri net is taken as a basic tool. On the basis of the basic structure and concept of studying fuzzy petri net, an electric network fault diagnosis algorithm based on weighted fuzzy petri net rule reasoning is proposed. First, a classical example system is taken to build weighted fuzzy petri net model of every component. Then the arithmetic is used to make logical verification and simulation. The simulation result shows that the arithmetic is feasibility and validity in network fault diagnosis. Finally, fault probabilities is provided to researchers for futher diagnosises. |
