基于贝叶斯网络的故障树在机械设备中的应用

Application of fault tree based on Bayesian networks in equipment

由于故障树分析方法在可靠性分析中存在局限性,研究贝叶斯网络在可靠性分析中的应用,给出了故障树向贝叶斯网络转化的方法,以及基于贝叶斯网络求解顶事件发生概率的算法.最后对发控设备进行了分析,结果表明,基于贝叶斯网络的故障树分析方法更贴近实际。

According to the deficiency of fault tree analysis in reliability analysis , fault tree analysis based on Bayesian networks is proposed. This paper is aimed at converting fault trees to Bayesian net works, and solving the probability of top event. Analyzed the equipment in the end, and the results show that the fault tree based on Bayesian networks is more practical.
