| Abstract: | A fuzzy reasoning Petri net(FRPN) model is defined in this paper to represent the fuzzy production rules of a rule based system. Based on the FRPN model, an efficient reasoning algorithm is proposed. The fuzzy reasoning algorithm is formally expressed using max algebra matrix equation, and has parallel reasoning ability. Through using this algorithm, the truth of all the statements in a system can be got from its initial state. An application to fault diagnosis system is explained through an example. |
