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) … WebJul 1, 2024 · 1. Introduction. Fault Tree Analysis (FTA) is commonly used to evaluate reliability of the complex and large scaled systems. Dynamic Fault Trees Analysis (DFTA) extend traditional FTA by defining a set of dynamic logical gates. 1, 2 The early approach to DFTA is Markov-based method 3, 4, which is vulnerable to the problem of well-known …
