A fuzzy fault tree formulated by a class of fuzzy measures
Bulletin of University of Osaka Prefecture. Series A, Engineering and natural sciences, 1987A fuzzy fault tree for fault analysis of soft systems is formulated by fuzzy measures of fuzzy sets. Fuzzy measures in this paper are based on t-norms and t-conorms. Measures of level-m fuzzy sets are defined recursively, which represent structure functions of the fault tree.

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.

Fuzzy fault tree analysis: revisited
International Journal of System Assurance Engineering and Management, 2011Fault tree analysis is one of the most effective techniques for estimating the frequency of occurrence of hazardous events in probabilistic risk assessment study. The analyst needs to study a multi component system and identifies vulnerable sections of hazardous plant based on formalized procedure. In this sequel, we have made an attempt to demonstrate

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.
