Fault tree analysis of fuzzy mechanical systems

Microelectronics Reliability, 1994
Abstract The fault tree techniques involve the decomposition of a system into a logic diagram or fault tree in which certain primary events lead to a specified top event that signifies the total failure of the system. The fault trees can be used to find the minimal cut sets which, when coupled with the failure rates of the primary events, lead to an ...

Reliability evaluation based on fuzzy fault tree

2010 IEEE 17Th International Conference on Industrial Engineering and Engineering Management, 2010
In 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.

Hybrid fault tree analysis using fuzzy sets

Reliability Engineering & System Safety, 1997
Abstract In conventional fault tree analysis (FTA), the ambiguous and imprecise events such as human errors tend not to be handled effectively. To overcome this disadvantage, a hybrid approach employing fuzzy set evaluation and probabilistic estimation for FTA is proposed to evaluate abnormal events.

Fuzzy Fault Tree Analysis for Structural Safety

Journal of Intelligent & Fuzzy Systems, 1996
A tool that can be used to assess structural safety is fault tree analysis (FTA) , which depends primarily on quantitative information. However, in many cases, safety assessment of civil engineering structures is based on subjective judgement. To improve the traditional FTA, the authors use the fuzzy set concept and introduce fuzzy fault tree analysis (

Safety risk assessment intelligent system for on-foot construction worker using fuzzy fault tree

Journal of Intelligent & Fuzzy Systems, 2021
A risk assessment model is developed to estimate the potential combined influence of concurrent safety risks facing on-foot construction worker at a certain point in space or instant of time. The model is based on a holistic approach that comprehensively

Fault tree analysis based on fuzzy logic

Computers & Chemical Engineering, 1990
Abstract 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

Fault Diagnosis Analysis of Gear Based on Fuzzy Fault Tree

Advanced Materials Research, 2011
The 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 ...
