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 ...

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.

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.

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 ...
