Dynamic Fault Tree Generation and Quantitative Analysis of System Reliability for Embedded Systems Based on SysML Models [PDF]
SensorsAs embedded systems become increasingly complex, traditional reliability analysis methods based on text alone are no longer adequate for meeting the requirements of rapid and accurate quantitative analysis of system reliability.

Fault isolation procedure analysis method based on dynamic fault tree
Hangkong gongcheng jinzhan, 2023 The traditional fault isolation program uses the conventional static fault tree for fault analysis,which may lead to incomplete fault cause analysis,too cumbersome fault isolation path and other problems.

The Dynamic Fault Tree Rare Event Simulator [PDF]
, 2020 The dynamic-fault-tree rare event simulator, DFTRES, is a statistical model checker for dynamic fault trees (DFTs), supporting the analysis of highly dependable systems, e.g. with unavailability or unreliability under 10^(-30). To efficiently estimate such low probabilities, we apply the Path-ZVA algorithm to implement Importance Sampling with minimal ...

A Hybrid Modular Approach for Dynamic Fault Tree Analysis
IEEE Access, 2020 Over the years, several approaches have been developed for the quantitative analysis of dynamic fault trees (DFTs). These approaches have strong theoretical and mathematical foundations; however, they appear to suffer from the state-space explosion and ...

Dynamic fault tree analysis based on the structure function [PDF]
2011 Proceedings - Annual Reliability and Maintainability Symposium, 2011 This paper presents an algebraic approach allowing to perform the analysis of any Dynamic Fault Tree (DFT). This approach is based on the ability to formally express the structure function of DFTs. We first present the algebraic framework that we introduced to model dynamic gates and hence be able to determine the structure function of DFTs.

Modular Criticality Analysis for Dynamic Fault Trees [PDF]
Fault trees are commonly used to model fault occurrence and propagation in safety-critical systems. A common analysis question is “how critical is a component failure for the overall system reliability?” These insights allow to guide and tailor system improvements.

Uncovering Dynamic Fault Trees [PDF]
2016 46th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2016 Fault tree analysis is a widespread industry standard for assessing system reliability. Standard (static) fault trees model the failure behaviour of systems in dependence of their component failures. To overcome their limited expressive power, common dependability patterns, such as spare management, functional dependencies, and sequencing are ...
