Approximate dynamic fault tree calculations for modelling water supply risks [PDF]

open access: yesReliability 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.

Rapid Fault Diagnosis Method of Elevator System Based on Multiattribute Decision Making

open access: yesShock 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.
