| 摘 要： | 将城市燃气输配系统划分为储配站、输配管网和用户三部分,在对城市燃气输配系统某一部分故障分析的基础上,建立了城市燃气输配系统的故障树模型。针对系统的事件发生概率不确定情况,将模糊数学引入到故障树方法,给出了燃气输配系统的模糊故障树安全评估方法。研究表明,该方法用于输配系统的安全评估是行之有效的。

| Abstract: | In this paper,the urban gas transmission and distribution system is classified into three parts: tank factory,pipelines and client.Based on trouble analyzing of various parts of urban gas transmission and distribution system,a fuzzy fault tree of urban gas transmission and distribution system is built.To solve the problem of uncertain failure rate of root and mid events,fuzzy theory is introduced into the fault tree analysis,and fuzzy fault tree based safety assessment method is given for urban gas transmission and distribution system.The failure rate of root events is described as fuzzy number.Practical results show that this method is effective to assess the system. |
