WebNov 2, 2024 · Fault tree analysis (FTA) is an analysis method that allows the determination of the factors contributing to the occurrence of undesirable events and the probability of occurrences. Li and Gao (2024) [ 46 ] indicated the necessity of determining the potential factors and root causes in a system using the FTA method. WebThe explosive logic network( ELN) with two-input-oneoutput was designed with three explosive logic gap null gates. The time window of the output of the ELN was given,after which the dynamic fault tree analysis was implemented. Two dynamic failure modes of the ELN were obtained,and then their own Markov transition processes were established. campground near rocky mountain house campground near red river gorge
