Research on Damage Tree Bayesian Network Simulation Metamodel Based on Fault Tree Analysis

Abstract

It is difficult for the fault tree analysis method to fully adapt to the needs of damage tree analysis. Based on the original model of the damage tree, the corresponding Bayesian network simulation metamodel is constructed based on the internal relationship between the damage of equipment components reflected by the damage tree. The analysis of the damage tree from the Bayesian network perspective effectively solves the two key problems of the rapidity of damage location and the common cause of damage bottom event.
