A review on the realization methods of dynamic fault tree

Abstract

Dynamic fault tree (DFT) is an extended technology of Fault tree analysis (FTA). It has been widely used in many fields and plays an important role in improving the security performance of the system. Although DFT has developed for many years, new research in recent years is still worthy of attention. In this study, the research status of different realization methods/analysis techniques of DFT is comprehensively reviewed. First, the development and research trend of DFT are described. Second, the research on dynamic gates and components in the analysis techniques is introduced in detail. Third, the mainstream realization methods of DFT, such as Markov chain, Bayesian network (BN) and so on, are summarized. At the same time, the application of other auxiliary analysis techniques is also introduced. Then, based on the research progress of different realization methods, the future development direction and challenges of DFT are prospected. The realization methods of DFT not only need the rigorous theoretical foundation. Moreover, it is also necessary to consider the combination of real‐time data and system modeling technology to realize dynamic assessment and smart system in the future.

Integration frameworks and intelligent research in dynamic fault tree: A comprehensive review and future perspectives

“…Besides, the cluster of “#4 chemical process industry” has always been a hot domain of DFT technology and the origin of this technology. Moreover, the review and analysis of DFT implementation methods are discussed in more detail in another work 18 . Especially about dynamic gates, such as PAND gate, 18 SPARE gate, 19 SEQ gate, 20 etc.…”

A reliability analysis technique for complex systems with retaining fuzzy information

“…Numerous reliability analysis models have been developed to address the challenges posed by intricate failure behaviors in safety‐critical systems. Some widely adopted models include Fault Tree (FT), 2 Dynamic Fault Tree (DFT), 3 Reliability Block Diagram (RBD), 4 Stochastic Petri Nets (SPN), 5 Bayesian Networks (BN), 6 and Dynamic Bayesian Networks (DBN) 7 . Fault Tree Analysis (FTA) focuses on the identification and quantification of failure events that may lead to system failures 8 .…”
