Integrating Fault Tree Analysis with Event Ordering Information
Fault tree analysis is a traditional and well-established technique for analyzing system design and robustness. Its purpose is to identify sets of basic events, called cut sets, which can cause a given top level event, e.g., a system malfunction, to occur. In this paper we present an algorithm that extracts ordering information, i.e., finds out possible ordering constraints which are required t...
متن کاملA New Ordering Method of Basic Events in Fault Tree Analysis
The ordering of basic events is critical to fault tree analysis on the basis of binary decision diagrams (BDDs). Many attempts have been made to seek an efficient ordering result with the aim of reducing the complexity of BDD. In this article, a new ordering method, namely, priority ordering method, is proposed. The new method takes into account not only the effects of the layers of fault tree ...
متن کاملOvercoming the uncertainty in a research reactor LOCA in level-1 PSA; Fuzzy based fault-tree/event-tree analysis
Probabilistic safety assessment (PSA) which plays a crucial role in risk evaluation is a quantitative approach intended to demonstrate how a nuclear reactor meets the safety margins as part of the licensing process. Despite PSA merits, some shortcomings associated with the final results exist. Conventional PSA uses crisp values to represent the failure probabilities of basic events. This causes...
متن کاملDFTCalc : A Tool for Efficient Fault Tree Analysis ( extended
Effective risk management is a key to ensure that vital assets like our nuclear power plants, medical equipment, and power grids are dependable. Also, risk management is often required by law. Fault Tree Analysis (FTA) is a widely used methodology here, computing important dependability measures like system reliability and availability. This paper presents DFTCalc, a powerful tool for FTA that ...
