The Dynamic Fault Tree Rare Event Simulator [PDF]
, 2020 The dynamic-fault-tree rare event simulator, DFTRES, is a statistical model checker for dynamic fault trees (DFTs), supporting the analysis of highly dependable systems, e.g. with unavailability or unreliability under 10^(-30). To efficiently estimate such low probabilities, we apply the Path-ZVA algorithm to implement Importance Sampling with minimal ...

Dynamic Fault Tolerance with Misrouting in Fat Trees [PDF]
2006 International Conference on Parallel Processing (ICPP'06), 2006 Fault tolerance is critical for efficient utilisation of large computer systems. Dynamic fault tolerance allows the network to remain available through the occurance of faults as opposed to static fault tolerance which requires the network to be halted to reconfigure it.

Rapid Fault Diagnosis Method of Elevator System Based on Multiattribute Decision Making
Shock and Vibration, 2021 Fault tree analysis is often used in elevator fault diagnosis because of its simplicity and reliability. However, the traditional fault tree method has the problems of low efficiency due to ignoring location change of bottom events during troubleshooting.

Journal of Mathematics, 2021 There are many reasons for escalator reversal failure, and the reasons are distributed in different locations. It is difficult to locate the specific location of the fault in the actual fault troubleshooting.

Towards a sound semantics for dynamic fault trees [PDF]
Reliability Engineering & System Safety, 2015 Abstract In this article, we study the semantics of dynamic fault trees and related formalisms. We suggest that there are actually three mechanisms at work in dynamic fault trees: first, changes of states due to occurrences of events, second bottom-up propagations of values as in static fault trees, and third top-down propagations of demands of ...
