New gate operations of fuzzy fault tree analysis
Proceedings of 1994 IEEE 3rd International Fuzzy Systems Conference, 2002Fault tree analysis (FTA) is a widely used method for system analysis in which a particular type of fault is expanded deductively to several causes (events) and basic causes (events) are determined. The representation of the relationship between the occurrence of an upper event and that of the lower events is called a gate operation.

Fuzzy fault tree analysis of a power transformer
2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012Power transformer is an essential and integral part of any power system. Failure of power transformer affects the working of entire system. Since failure probability is smaller as compared to success, it is easier to carry out the failure analysis for estimating the success probability.

GIS reliability analysis based trapezoid fuzzy fault tree
2010 18th International Conference on Geoinformatics, 2010GIS reliability refers to the ability to complete the requirements under the specified conditions and time. In this paper, there are five elements including object, conditions of use, use of time, functions and capabilities, to evaluate GIS reliability proposed by the combination in a engineering GIS.

A new method for fuzzy fault tree analysis
Microelectronics Reliability, 1989It is well-known that the conventional fault tree analysis using probabilities has been found to be inadequate to handle the imprecision of input failure data and the uncertainties associated with the modelling particularly in relation to dependency of failures.

A fuzzy diagnosis approach using dynamic fault trees
Chemical Engineering Science, 2002Abstract By incorporating digraph models, fault trees and fuzzy inference mechanisms in a unified framework, a novel approach for fault diagnosis is developed in this work. To relieve the on-line computation load, the fault origins considered in diagnosis are limited to the basic events in the cut sets of a given fault tree.

Method of fuzzy fault tree analysis
2008This paper presents the possibility of extension of the classical fault tree analysis FTA with the fuzzy fault tree analysis FFTA. The integration of the FFTA within the tree fault is presented as well as the example of the simulation of the fuzzy sets basic events with affiliated functions of affiliation.

Fuzzy Fault Tree Analysis of Railway Traffic Safety
Traffic and Transportation Studies (2000), 2000The safety analysis of railway traffic system is presented in this paper. Fuzzy fault tree technique has been adopted in safety analysis. The main traffic accidents—top events of fault trees—have been analyzed down to the level of human errors and hardware failures. In the fuzzy fault-tree model, the possibility of failure, i.e.
