| Abstract: | This article conducts a qualitative and quantitative failure analysis of the fault tree model of urban gas transmission and distribution system based on fault tree analysis.In accordance with the uncertainty of the event probability,it introduces fuzzy mathematics to the fault tree analysis and proposes the fuzzy fault tree safety assessment method of the transmission and distribution system.Practical results show that the method is effective when assessing the safety of the transmission and distribution system. |
