Dynamic fault tree analysis
WebAbstract: Traditional static fault tree analysis is widely used to analyze the reliability of complex systems in different fields. To improve their reliability and availability values of complex redundant systems, lots of dynamic gates are used, such as Priority AND (PAND) Gate, Spare Gate, Sequence Enforcing (SEQ) Gate and Functional Dependency (FDEP) … WebFTA analysis involves five steps: Define the undesired event to study. Definition of the undesired event can be very hard to uncover, although some of the... Obtain an …

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.
