The purpose of this study was to use fault tree analysis to evaluate the adequacy of quality reporting programs in identifying root causes of postoperative bloodstream infection (BSI). A systematic review of the literature was used to construct a fault tree to evaluate 3 postoperative BSI reporting programs: National Surgical Quality Improvement ...

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 ...

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.

Fault tree or root cause analysis (FTA) is the most often used graphical deductive system analysis. It is by now the working horse in all fields with higher demands regarding reliability, availability, safety, and availability. It is increasingly also used in the domain of engineering resilience for assessing sufficient efficient response to expectable

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 ...

Abstract Fault-tree analysis is a graphical technique that identifies all events and combinations of events that can produce an undesired event. This chapter emphasizes several fault-tree analysis concepts, examining with examples how all three categories of charting symbols (events, gates, and transfer symbols) come together to generate

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.

On the significance of fault tree analysis in practice
2009 IEEE Conference on Emerging Technologies & Factory Automation, 2009With increasing system complexity and extensive use of computerized control of industrial processes and plants, it is essential to have a systematic approach for identifying failures that can expose people and environment for unacceptable risks. With focus on a drive system used to control a linear motor, the fault tree analysis method is utilized to ...

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.
