摘要
基于一般 Petri网理论、故障树技术和模糊集理论 ,建立了适用于故障诊断的模糊 Petri网理论体系 ,并用于 FMS的故障诊断实例中。该方法具有直观、表达能力强、易于推理 。
Based on the theory of general Petri net, fault tree technique and theory of fuzzy set, a theory system of fuzzy Petri net suitable for fault diagnosis is established, which is used for an example of fault diagnosis for FMS. This method has the advantages of objectivity, strong expression ability,easy inference, etc. and it can exactly describe the properties of fault phenomenon and coherence of fault space.
