摘要
阐述了贝叶斯网络信念的传播与更新,说明了故障树向贝叶斯网络转化的过程,其中包括联接强度与逻辑门的映射关系与主要转化步骤。使用贝叶斯网络对长输管道进行了安全失效分析,提出了贝叶斯网络对故障树分析的二态性与逻辑确定性的修正。
The propagation and update of network belief were presented, the converting of fault tree to Bayesian networks was shown, including the mapping of connected intensity to logical gate and the translation of approach. The oil and gas pipeline＇ s failure analytic that was based on Bayesian networks were processed. Finally, the modifies of Bayesian to failure tree that was based on dimorphism and logic confirm were expounded.
