摘　　要：利用模糊Petri网的动态性、并发性和模糊性,可很好描述故障现象的动态产生和传播过程,能合理描述知识库中知识所固有的并发性、模糊性。本工作将模糊Petri网拓展为加权模糊Petri网,采用粒子群优化算法对Petri网的权值和阈值进行优化,减小了对专家经验的依赖,有效地提高了模糊Petri网的泛化能力。The dynamic concurrency and fuzzy of the fuzzy Petri net can well describe the dynamic and spread process of the fault and the concurrency and fuzzy of the knowledge in knowledge database.Fuzzy Petri net was expanded to weight fuzzy Petri net,and particle swarm optimization was used to optimize the weight and threshold of the Petri net,this reduces the reliance on the expert＇s experience and effectively improves the generalization ability of the fuzzy Petri net.
