| 摘 要： | 文章简要阐述了贝叶斯网络的构造原理和网络信念的传播与更新,并详细说明了故障树向贝叶斯网络转化的过程,主要包括结点与事件的映射关系和联接强度与逻辑门的映射关系.最后通过一个实例说明了故障树向贝叶斯网络的转化过程,并对二者的推理功能进行了比较.

| Abstract: | The building of network and the propagation and update of network belief are presented, the converting of fault tree to Bayesian networks is shown, including the mapping of node to event and the mapping of connected intensity to logical gate. Finally, the converting of fault tree to Bayesian networks is illustrated according to a instance, and their reasoning functions are compared. |
