Reliability Engineering and System Safety, 2002
Abstract The fault tree analysis is a widely used method for evaluation of systems reliability and nuclear power plants safety. This paper presents a new method, which represents extension of the classic fault tree with the time requirements. The dynamic fault tree offers a range of risk informed applications.

Diagnosis of Faults in Modular Trees
IEEE Transactions on Computers, 1979Diagnosis of stuck-at faults (s-a-f's) in modular trees is studied. Detection conditions for each distinguishable s-a-f in a module are derived. For single s-a-f's, the detection conditions are easily partitioned to achieve fault location by performing a small number of additional tests. A multiple s-a-f that produces the same test result as a single s-

Classification of fault trees and algorithms of fault tree analysis
Microelectronics Reliability, 1990Abstract A new classification of fault trees is proposed, and the relationship between the new and old classifications is discussed. The new classification is illustrated with an example, and the limitation of the well-known simple prime implicant algorithm, which can work on fault trees, is shown.

Where is the fault in fault trees?
Journal of Experimental Psychology: Human Perception and Performance, 1994When branches of a fault tree are pruned, their probabilities are not fully transferred to the "all other" branch. We test 3 explanations for this underestimation of the "all other" probability: availability, ambiguity, and credibility. In an experiment, we varied the credibility of a cover story and separately observed the generation of a fault's ...

Abstract Fault tree (FT) is a simple, visual, popular and standardized notation for representing relationships between a fault in a system and the associated events. FTs are widely used for supporting products and systems in diverse industries like process control, avionics, aerospace, nuclear power systems, etc.

Fault tree analysis, as many other dependability evaluation techniques, relies on given knowledge about the system architecture and its configuration. This works sufficiently for a fixed system setup, but becomes difficult with resilient hardware and software that is supposed to be flexible in its runtime configuration.

From Fault-Tree To Fault-Identification
IEEE Transactions on Reliability, 1983Summary: A practical way is given of identifying actual faults, by using a fault tree's complete system of minimal cutsets. For instance, for a fault tree where 20 cutsets are considered with 30 possible primal events, any of them can be found in at most three steps by the proposed FID-algorithm.

Fault Trees vs. Component Fault Trees: An Empirical Study
2018When dealing with structural safety analysis, one of the most popular methodologies is Fault Tree Analysis (FTA). However, one major critique is the rapid increasing of the complexity, and therefore incomprehensibility, when dealing with realistic systems.

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 ...

Analysis of software fault trees exposes hardware and software failure events that lead to unsafe system states, and provides insight on improving safety throughout each phase of the software lifecycle. Software product lines have emerged as an effort to achieve reuse, enhance quality, and reduce development costs of safetycritical systems.
