A review on the realization methods of dynamic fault tree
Quality and Reliability Engineering International, 2022AbstractDynamic 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.

Approximate dynamic fault tree calculations for modelling water supply risks
Reliability Engineering and System Safety, 2012 Traditional fault tree analysis is not always sufficient when analysing complex systems. To overcome the limitations dynamic fault tree (DFT) analysis is suggested in the literature as well as different approaches for how to solve DFTs.

Monte Carlo simulation to solve fuzzy dynamic fault tree*
IFAC-PapersOnLine, 2016 International audienceProbabilistic risk analysis (PRA) is the most widely used method in risk analysis studies to look at the frequency and consequences of the occurrence of an undesirable events.

Dynamic Fault Tolerance in Fat Trees
IEEE Transactions on Computers, 2011Fat trees are a very common communication architecture in current large-scale parallel computers. The probability of failure in these systems increases with the number of components. We present a routing method for deterministically and adaptively routed fat trees, applicable to both distributed and source routing, that is able to handle several ...

Symmetry, 2022 Product fault diagnosis has always been the focus of quality and reliability research. However, a failure–rate curve of some products is a symmetrical function, the fault analysis result is not true because the failure period of the products cannot

Scalable Analysis of Fault Trees with Dynamic Features
2015 45th Annual IEEE/IFIP International Conference on Dependable Systems and Networks, 2015Fault trees constitute one of the essential formalisms for static safety analysis of various industrial systems. Dynamic fault trees (DFT) enrich the formalism by time-dependent behavior, e.g., repairs or functional dependencies. Analysis of DFT is so far limited to substantially smaller models than those required for, e.g., nuclear power plants.

Dynamic Reliability Block Diagrams VS Dynamic Fault Trees
2007 Proceedings - Annual Reliability and Maintainability Sympsoium, 2007Reliability block diagrams (RBD), and fault trees (FT) are the most widely used formalisms in system reliability modeling. They implement two different approaches: in a reliability block diagram, the system is represented by components connected according to their function or reliability relationships, while fault trees show which combinations of the ...

Effective Static and Dynamic Fault Tree Analysis
2016Fault trees constitute one of the essential formalisms for static safety analysis of various industrial systems. Dynamic fault trees (DFT) enrich the formalism by support for time-dependent behaviour, e.g., repairs or dynamic dependencies. This enables more realistic and more precise modelling, and can thereby avoid overly pessimistic analysis results.

On-Line Fault Diagnosis Using Dynamic Fault Tree
IFAC Proceedings Volumes, 2001Abstract By incorporating SDG, FTA and fuzzy inference techniques, a novel framework for fault diagnosis is developed in this paper. To relieve the on-line computation load, the scope of diagnosis is limited to the fault origins leading to the top events of given fault trees. The corresponding fault propagation patterns are derived from SOG model and

Time Parallel Simulation for Dynamic Fault Trees
2014Dynamic Fault Trees (DFT) are a generalization of Fault Trees which allow the evaluation of the reliability of complex and redundant systems. We propose to analyze DFT by a new version of time-parallel simulation method we have recently introduced. This method takes into account the monotonicity of the sample-paths to derive upper and lower bounds of ...
