Study on Safety Risk of Railway Vehicle Hydrogen Refueling Station Based on T-S Fuzzy Fault Tree and Bayesian Network
摘要
According to the requirements of operation safety in railway vehicle hydrogen refueling station, the risk factors affecting the operation safety were selected, the calculation formula of evaluation index was derived, and the Bayesian network model based on T-S fuzzy fault tree was constructed. The triangular membership function, the fuzzy subset of failure probability and the posterior probability formula were used to verify the availability of the safety risk assessment method.
