Fuzzy Fault Tree Based Fault Detection
2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing, 2012In this article, for the Linux operating system environment, with the characteristics of ambiguity and uncertainty for the occurrence probability of system failures, fuzzy theory is introduced into the fault tree analysis. The occurrence probability of basic events in the conventional fault tree is made fuzzy by introducing the concept of fuzzy sets ...

Fault-Tree Analysis by Fuzzy Probability
IEEE Transactions on Reliability, 1983In 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 Fuzzy Decision Tree for Fault Classification
Risk Analysis, 2008In plant accident management, the control room operators are required to identify the causes of the accident, based on the different patterns of evolution of the monitored process variables thereby developing. This task is often quite challenging, given the large number of process parameters monitored and the intense emotional states under which it is ...

Fault tree analysis with fuzzy gates
Computers & Industrial Engineering, 1997Abstract 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 ...

Fuzzy importance in fault tree analysis
Fuzzy Sets and Systems, 1984In fault tree analysis, system success or failure can be described by the state of the top event, which is usually defined by a so-called structure function. In this paper, we attempt to simplify the calculation process of the structure function and to newly define the state of the top event by the membership function, using fuzzy sets theory ...
