基于故障树贝叶斯网络的装备故障诊断方法研究

针对复杂系统故障诊断的难点，通过某装备信息机的实例给出了一种基于故障树贝叶斯网络的故障诊断方法。该方法通过结构转变、证据传播，采用局部计算进行故障概率推理，不仅使FBN故障概率推理简洁易行，而且使FBN故障概率推理的复杂性大大降低。

Fault Tree Method of Fault Diagnosis Equipment Based on Bayesian Networks

Fault diagnosis for complex and difficult,machine equipment information through an instance of a given fault tree based on Bayesian network fault diagnosis.In this method,structural changes,evidence propagation,failure probability calculation using partial reasoning,probabilistic reasoning not only simple and easy to FBN fault line,but also the complexity of probabilistic inference FBN failure is greatly reduced.
