Fault isolation procedure analysis method based on dynamic fault tree
Hangkong gongcheng jinzhan, 2023 The traditional fault isolation program uses the conventional static fault tree for fault analysis,which may lead to incomplete fault cause analysis,too cumbersome fault isolation path and other problems.

Advancing Dynamic Fault Tree Analysis
, 2016 This paper presents a new state space generation approach for dynamic fault trees (DFTs) together with a technique to synthesise failures rates in DFTs. Our state space generation technique aggressively exploits the DFT structure --- detecting symmetries,

A Hybrid Modular Approach for Dynamic Fault Tree Analysis
IEEE Access, 2020 Over the years, several approaches have been developed for the quantitative analysis of dynamic fault trees (DFTs). These approaches have strong theoretical and mathematical foundations; however, they appear to suffer from the state-space explosion and ...

Constraint analysis for extended dynamic fault tree
Tongxin xuebao, 2017 As a new extension of dynamic fault trees,time delay gate was proposed.This new mechanism can be used to model the time delay on the fault propagation from the lower level subsystems to the higher level system.The dynamic Bayesian networks was extend to ...

Uncovering Dynamic Fault Trees [PDF]
2016 46th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2016 Fault tree analysis is a widespread industry standard for assessing system reliability. Standard (static) fault trees model the failure behaviour of systems in dependence of their component failures. To overcome their limited expressive power, common dependability patterns, such as spare management, functional dependencies, and sequencing are ...

Application of dynamic fault tree in reliability assessment of reactor protection system
He jishu, 2021 Background Reactor protection system (RPS) has complex structure, numerous equipment, and continuous failure behaviors. The traditional static fault tree cannot accurately simulate the sequential failure behaviors of the RPS.

Rare event simulation for dynamic fault trees [PDF]
Reliability Engineering & System Safety, 2017 Fault trees (FT) are a popular industrial method for reliability engineering, for which Monte Carlo simulation is an important technique to estimate common dependability metrics, such as the system reliability and availability. A severe drawback of Monte Carlo simulation is that the number of simulations required to obtain accurate estimations grows ...
