Fault tree based diagnostics using fuzzy logic
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1990Fuzzy set theory is investigated as a tool for the diagnostics of systems described by means of a fault tree. The objective is to diagnose component failures from the observation of fuzzy symptoms using the information contained in a fault tree. A two-step procedure is used to solve the problem.

An Approach of Fault Diagnosis for System Based on Fuzzy Fault Tree
2008 International Conference on MultiMedia and Information Technology, 2008Due to the complicacy of the communication control system (CCS) structure and the variations in operating conditions, the occurrence of a fault inside CCS is uncertain and random. Aiming at limitations of the current fault diagnosis of CCS, the paper presents an approach to fault diagnosis of fuzzy fusion based on fuzzy fault tree.

Fault Diagnosis Analysis of Gear Based on Fuzzy Fault Tree
Advanced Materials Research, 2011The complexity of modern equipment is higher than before, thus it cannot meet the need of speedy fault diagnosis to use single diagnosis pattern. According to these troubles, a fault tree was introduced to analyze fault information of gear. Fault tree analysis is a logical and diagrammatic method to evaluate the probability of an accident resulting ...

Reliability of a Transport Node based on Fuzzy Fault Tree Analysis
2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2021In this work to be introduced a fuzzy fault tree real time algorithm to identify reliability of highly autonomous driving (HAD) redundant system of a traffic node. The fuzzyfication of the fault tree procedure was realized by expressing the basic events with a membership function. Logical gates had to be generalized based on incoming fuzzy events. Node

A reliability risk analysis method based on the fuzzy fault tree and fuzzy event tree
2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS), 2016Based on the analyses systems of fuzzy fault tree and event tree, this paper proposes a method for a reliability risk analysis to mitigate problems associated with risk modeling of fuzzy and uncertain information. Risk event occurrence probabilities were obtained with fuzzy linguistic variables instead of exact values used in fault tree analysis ...

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.

Reliability evaluation based on fuzzy fault tree
2010 IEEE 17Th International Conference on Industrial Engineering and Engineering Management, 2010In conventional fault tree analysis (FTA), some complex and uncertain events such as human errors cannot be handled effectively. Fuzzy fault tree analysis (fuzzy FTA) integrating fuzzy set evaluation and probabilistic estimation is proposed to evaluate vague events.

Fault Tree Analysis Based on Fuzzy Logic
2007 Annual Reliability and Maintainability Symposium, 2007Accurate assessment of system reliability with limited or insufficient statistical data is difficult. This paper presents a method which overcomes the drawbacks of traditional fault tree analysis (FTA) by using FTA based on possibilistic measures and fuzzy logic.
