摘要

系统可靠性分析是近年来研究的热点之一。本文利用高速动车组故障的特点,在加权模糊产生规则和模糊petri网的基础上,提出了一种加权模糊petri网模型。它用于诊断性知识表示和推理。该模型可以有效地处理信息不精确的故障与标志之间复杂的关系问题。将离散事件动态系统中petri网的分析技术应用于高速列车可靠性分析。为解决系统可靠性问题提供了一种新的方法。

The Research of System Reliability Calculation Method Based on the Improved Petri Net
System reliability analysis becomes one hot topic of research in recent years. This paper takes advantage of the characteristics of high speed bullet train fault, on the basis of the weighted fuzzy production rule and fuzzy petri net, and puts forward a weighted fuzzy petri net model. It is used for diagnostic knowledge representation and reasoning. This model can effectively deal with the issues of the complicated relationship between the fault of imprecise information and the signs. The analysis technology of petri nets Described in discrete event dynamic systems is applied to the high-speed train reliability analysis. It provides a new method to resolve the problem of system reliability.
