The Galileo fault tree analysis tool
Digest of Papers. Twenty-Ninth Annual International Symposium on Fault-Tolerant Computing (Cat. No.99CB36352), 2003We present Galileo, a dynamic fault tree modeling and analysis tool that combines the innovative DIF-Tree analysis methodology with a rich user interface built using package-oriented programming. DIFTree integrates binary decision diagram and Markov methods under the common notation of dynamic fault trees, allowing the user to exploit the benefits of ...

Fault tree analysis of computer systems
Proceedings of the June 13-16, 1977, national computer conference on - AFIPS '77, 1977Fault Tree Analysis (FTA) is a well developed technique for the reliability and safety analysis of complex systems such as nuclear power plants and weapon systems. In this paper, we apply FTA to analyze the reliability and the performance of computer systems.

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 ...

Compositional Temporal Fault Tree Analysis
2007HiP-HOPS (Hierarchically-Performed Hazard Origin and Propagation Studies) is a recent technique that partly automates Fault Tree Analysis (FTA) by constructing fault trees from system topologies annotated with component-level failure specifications. HiP-HOPS has hitherto created only classical combinatorial fault trees that fail to capture the often ...

Fuzzy fault tree analysis: revisited
International Journal of System Assurance Engineering and Management, 2011Fault tree analysis is one of the most effective techniques for estimating the frequency of occurrence of hazardous events in probabilistic risk assessment study. The analyst needs to study a multi component system and identifies vulnerable sections of hazardous plant based on formalized procedure. In this sequel, we have made an attempt to demonstrate

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.

Goal trees and fault trees for root cause analysis
2008 IEEE International Conference on Software Maintenance, 2008Typical enterprise applications are built upon different platforms, operate in a heterogeneous, distributed environment, and utilize different technologies, such as middleware, databases and Web services. Diagnosing the root causes of problems in such systems is difficult in part due to the number of possible configuration and tuning parameters.

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.
