Fuzzy fault tree analysis

Proceedings of 1994 IEEE 3rd International Fuzzy Systems Conference, 2002
Reliability of products is frequently a prime safety consideration. Interpretation of reliability is both quantitative and qualitative. Extensive quantitative analysis employing probablistic risk assessment has been widely performed to provide predicted hazard or accident minimization.

Employing Best–Worst Approach and Distance‐Similarity Measure Based Aggregation Method in Intuitionistic Fuzzy Fault Tree Analysis for Risk Assessment With Application to Coal Dust Explosion

Quality and Reliability Engineering International
Fault tree analysis is a widely used method for analyzing the failure causes of systems and evaluating system safety and reliability. It is sometimes difficult to obtain the precise failure data of system components contributing to the system failure ...

Fault tree based diagnostics using fuzzy logic

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1990
Fuzzy 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, 2011
Fault 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

Fault Tree Analysis Based on Fuzzy Logic

2007 Annual Reliability and Maintainability Symposium, 2007
Accurate 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.

Fuzzy fault-tree analysis using failure possibility

Microelectronics Reliability, 1993
Abstract In conventional probability-based fault-tree analysis, the vague property in many systems, especially, the man-machine system is often ignored. To overcome this disadvantage, the fuzzy set theory is applied to fault-tree analysis. The failure possibility defined by a triangular fuzzy number on the interval [0,1] is used to characterize the ...

Fuzzy fault tree analysis of mask stage

2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012
Fault tree analysis (FTA) is a top-down approach for failure analysis, starting with a potential undesirable event called a TOP event, and then determining all the ways it can happen. FTA is the most commonly used technique for causal analysis in risk and reliability studies. Mask stage an important part of lithography. In this paper, Fault Tree of the

Fuzzy Fault Tree Analysis : Case Studies

1995
Estimation of the fuzzy probability of occurrence of an hazardous event (such as: accidental release of chemicals) taking recourse to Fuzzy Sets Theory (FST) is the topic of immediate relevance in Probabilistics Risk Assessment for Chemical Industry.
