On the Analysis of Fault Trees
IEEE Transactions on Reliability, 1975The paper is concerned with the analysis of fault trees and describes an algorithm for deriving a reduced Boolean sum-of-product (s-o-p) expression from a description of the structure. The algorithm was developed initially as an analytic procedure for combinational logic networks and employs a reverse Polish notation to describe the structure which is ...

In this chapter, a state-of-the-art review of fault tree analysis is presented. Different forms of fault trees, including static, dynamic, and non-coherent fault trees, their applications and analyses will be discussed. Some advanced topics such as importance analysis, dependent failures, disjoint events, and multistate systems will also be presented.

Journal of Systems and Software, 1983
With the increased use of software in safety critical systems, software safety has become an important factor in system quality. This paper describes a technique, software fault tree analysis, for the safety analysis of software. The technique interfaces with hardware fault tree analysis to allow the safety of the entire system to be maximized ...

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.

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 ...

Proceedings of 1994 IEEE 3rd International Fuzzy Systems Conference, 2002
Reliability of products is frequently a prime safety consideration. Interpretation of reliability is both quantitative and qualitative. Extensive quantitative analysis employing probablistic risk assessment has been widely performed to provide predicted hazard or accident minimization.

Program for the Analysis of Fault Trees. [PDF]
, 1983 Abstract : Document describes PAFT F77, a program for the analysis of fault trees coded in Fortran 77. Given the structure of a fault tree and the probability or failure rates of its basic events, PAFT F77 calculates the probabilities of the top and all intermediate events, as well as the marginal importances of all basic events.

Multistate fault-tree analysis
Reliability Engineering & System Safety, 1990Abstract The recursive pivotal decomposition algorithm is a quantitative analysis method of binary fault-tree. In this article, the algorithm will be applied to the multistate case. As a result, a practical method of quantitative analysis of multistate fault-trees is given.
