Uncertainty Analysis of Fault-Tree Outputs
IEEE Transactions on Reliability, 1985Summary: The multiaffine nature of the top-event probability as a function of component unavailability is recognized. This leads, under the assumption of statistically independent failures, to the derivation of an exact formula relating the variance of the system unavailability to the variances of the component unavailability.

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-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 ...

Delay times in fault tree analysis
Microelectronics Reliability, 1982Abstract In reliability analysis of technical systems the failure frequency of cut sets alone is often insufficient to assess the probability of an undesired event. In many systems an undesired event occurs after failures of system elements, however not before a limited time period is over.

Fault-Tree Analysis Using a Binary Decision Tree
IEEE Transactions on Reliability, 1985Summary: A new algorithm for the production of a short disjoint-products form of a fault-tree output function is presented and discussed. This algorithm consists of a sequential binary decision process to find first big, then smaller sets of elementary system-failure states which correspond to disjoint-product terms.

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 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 ...

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 ...
