基于PRA方法的锅炉给水系统安全性定量分析

Quantitative Safety Analysis of the water supply system of boiler by the Probabilistic Risk Assessment

基于概率风险评估方法,对船用锅炉给水系统的失效模式进行了探讨,建立了给水系统失效故障树,求得了其最小割集。采用Monte-Carlo模拟仿真方法计算得到给水系统失效概率及底事件的重要度,据此提出了改进建议。

The failure modes of the marine boiler water supply are discussed based on the Probabilistic Risk Assessment method.The water supply system fault tree has been established and the minimum cut sets are obtained.The probability of the water supply system and the importance of root nodes is calculated by the Monte-Carlo simulation method.Some improvement advices are offered in the end.
