Fault-class-aware fault tree generation and analysis
2013 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2013Over decades, fault-tree has remained as one of the most widely used fault management (FM) mechanisms by practitioners as a visualization/communication media, as well as a quantitative analysis tool for building dependable systems. Nonetheless, to date fault tree analysis is often unable to provide us with high-confidence results due to potential ...

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 ...

Fault-Tree Analysis by Fuzzy Probability
IEEE Transactions on Reliability, 1983In conventional fault-tree analysis, the failure probabilities of components of a system are treated as exact values in estimating the failure probability of the top event. For many systems, it is often difficult to evaluate the failure probabilities of components from past occurrences because the environments of the systems change.

Fault-tree analysis of intermittent events
International Journal of Systems Science, 1986This paper presents a bottom-up methodology for sequential reduction of fault tree end-branches with intermittent events. The methodology can be used in conjunction with ordinary events with permanent state change.

, 1998 Fault tree network analysis for construction
Civil Engineering Systems, 1988Abstract This paper introduces a new technique in construction networking. A modified fault tree analysis was employed to determine the critical paths, sequence of activities, and the basic events that have the potential to induce the delays of any activity in the network. This method can be used for both deterministic and non-deterministic approaches.

Fault-tree analysis of technological failures
Proceedings of Engineering Management Society Conference on Managing Projects in a Borderless World, 2002The technological development process at the company level in a developing country is a complex, longitudinal process and is laden with many a failure. Failures can be either at the adoption, adaptation or innovation stages. This article, based on a field study of 89 manufacturing firms in the Indian capital goods sector, presents technological ...

Fault Tree Analysis with Probability Evaluaticn
IEEE Transactions on Nuclear Science, 1971Reliability analysis is playing an increasingly important role in quantitative assessment of system performance for assuring nuclear safety, improving plant performance and plant life, and reducing plant operating costs. In particular, fault tree analysis with probability evaluation provides an all inclusive, versatile mathematical tool for analyzing ...

Decomposition Methods for Fault Tree Analysis
IEEE Transactions on Reliability, 1980Some kinds of fault tree analysis are described for which cut set enumeration is inadequate. Modularization leads to more efficient computer programs, and also identifies subsystems which are intuitively meaningful. The problem of finding all modules of a fault tree is formulated as as extension of the problem of finding all ``cut-points'' of an ...
