Fuzzy fault tree analysis of mask stage
2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012Fault 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

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.

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.

Fault tree analysis based on TOPSIS and triangular fuzzy number
International Journal of System Assurance Engineering and Management, 2014Fault tree analysis (FTA) is widely used in the failure probability evaluation of a system. The conventional failure probabilities of basic events are treated as crisp values. However, in many real applications, it is often difficult to evaluate failure probabilities of basic events from past occurrences.

Fault tree analysis based on fuzzy logic
Computers & Chemical Engineering, 1990Abstract This paper considers the relative frequencies of basic events determining the safety of such a system as fuzzy numbers and uses instead of probabilistic possibilistic considerations for evaluating the mean values and the tolerances for the frequency of head events. Using standard approximations for the membership function expressions for the

Grey relation analysis on fuzzy fault tree of disk brake
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011The fault states are fuzzy and the relationship between the primary and the secondary factor leading to the fault is uncertain in the course of the reliability analysis of disk brake. To solve these problems, the fuzzy grey relation analysis is used to improve the traditional method, Fault Tree Analysis (FTA).

Fuzzy grey fault tree analysis on diesel engine reliability
2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery, 2010The minimal cut sets and structure importance of bottom event are achieved by top-down method on diesel engine system downtime failures. The method of combining grey relational analysis with fuzzy membership function is presented to solve the probability of failure modes. Fuzzy grey fault tree model is proposed.

Failure probability analysis by employing fuzzy fault tree analysis
International Journal of System Assurance Engineering and Management, 2017A significant number of accidents occur every year in chemical plants because of the failure of components. In order to manage this risk, fault tree analysis (FTA), a well-known method, was employed for failure probability analysis in the mentioned field. A complete access to the failure data is vital for quantitative FTA. There is always a shortage of
