Research on the Application of Fuzzy Bayesian Network in Risk Assessment of Catenary Construction

The research on risk control during the construction stage of catenary is relatively limited. Based a comprehensive analysis factors construction, this study determined causal relationships between and established assessment model for that analyzed risks from logic perspective. During evaluation process, we identified six exogenous variables twenty-one endogenous in based literature review field expert opinions, described cause-and-effect using structural equations diagrams, multi-level model. fuzzy experience, occurrence probability conditional were determined, respectively. Then, Bayesian Network was constructed to analyze process. results showed personal quality personnel sense responsibility supervision unit had great impact level construction. findings can help fully consider various weak points thereby ensuring efficient high-quality
