Causality and Temporal Dependencies in the Design of Fault Management Systems [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 Reasoning about causes and effects naturally arises in the engineering of safety-critical systems. A classical example is Fault Tree Analysis, a deductive technique used for system safety assessment, whereby an undesired state is reduced to the set of ...

Fault tree analysis for maintenance needs [PDF]
Journal of Physics: Conference Series, 2012 One of the key issues in maintenance is to allocate focus and resources to those components and subsystems which are the most unreliable and prone to failures. In industrial systems, fault tree analysis technique can be used to study the reliability of the complex systems and their substructures.

Formal Fault Tree Analysis - Practical Experiences
Electronic Notes in Theoretical Computer Science, 2007 AbstractSafety is an important requirement for many modern systems. To ensure safety of complex critical systems, well-known safety analysis methods have been formalized. This holds in particular for automation sytsems and transportation systems. In this paper we present the formalization of one of the most wide spread safety analysis methods: fault ...

Ontology-Based Fault Tree Analysis Algorithms in a Fuzzy Environment for Autonomous Ships
IEEE Access, 2021 This study deals with fault tree analysis algorithms based on an ontology-based approach in a fuzzy environment. We extend fuzzy fault tree analysis by embedding ontology-based fault tree structures. The ontology-based approach allows conducting advanced

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.
