Research and Application of Evidence Synthesis FTA Model Based on Similarity Analysis

Abstract:

In order to integrate multiple experts' opinions effectively, a fault tree analysis model based on the similarity is presented in this paper. First, the concept of similarity used to fuse data is introduced to analyze the similarity among multiple experts' opinions, and to assign each expert's opinions credibility weights based on the analysis results. Then, experts' opinions is synthesized by evidence theory, the probability of accident is predicted, and the importance degrees of basic events which may lead to top event occur is judged. Finally, a quantitative FTA model for the gas poison is established to compute the probability of top event and identify the most dangerous path which may lead to the accident, the results of analysis provide references to the managers when they develop validity measures.
