Fuzzy fault tree analysis: a review of concept and application

International Journal of Systems Assurance Engineering and Management, 2013
Fault tree analysis (FTA) is a widely used method for analyzing a system’s failure logic and calculating overall reliability. However, application of conventional FTA has some shortcomings, e.g. in handling the uncertainties, allowing the use of linguistic variables, and integrating human error in failure logic model.

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 ...

Fault-Tree Analysis by Fuzzy Probability

IEEE Transactions on Reliability, 1983
In the present approach based on a fuzzy fault-tree model, the maximum possibility of system failure is determined from the possibility of failure of each component within the system according to the extension principle. In calculating the possibility of system failure, some approximation is made for simplicity.

A new method for fuzzy fault tree analysis

Microelectronics Reliability, 1989
It 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.

Uncertainty in fault tree analysis: A fuzzy approach

Fuzzy Sets and Systems, 1996
Abstract In fault tree analysis, the uncertainties in the failure probability and/or failure rate of system components or basic events can be propagated to find the uncertainty in the overall system failure probability. The conventional approach is Monte-Carlo simulation by assuming a probability distribution for the failure probability. In addition,

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 ...

Fault tree analysis with fuzzy gates

Computers and Industrial Engineering, 1997
Abstract Fault tree analysis is an important tool analyzing system reliability. Fault trees consist of gates and events. Gates mean relationships between events. In fault tree analysis, AND, OR gates have been used as typical gates but it is often difficult to model the system structure with the two gates because in many cases we have not exact ...
