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. Web4.2 Dynamic fault trees and dynamic gates. The fault-tree model in the traditional fault-tree analysis cannot capture the sequence dependencies in the system. 7, 24 DTF extends the traditional one by adding four dynamic gates, which are the priority AND (PAND) gate, the sequence enforcing (SEQ) gate, the functional dependency (FDEP) gate, and ...
