摘要
根据故障诊断的特点 ,将概率信息引入Petri网 ,提出了故障诊断概率网模型。利用概率信息处理冲突消解问题 ,寻找最有可能发生的故障传播路径 ,提高了诊断效率 ,并以异常输入引发的故障为例对概率的确定问题进行了研究。
This paper presents the Probability Petri Nets(PPN) for mechanic fault diagnosis which contains probability information according to the characteristics of fault diagnosis. The probability information is used to solve the conflict problem and find out the most possible causes for faults. Finally, the method for probability calculation is studied as well.
