Causality and Temporal Dependencies in the Design of Fault Management Systems [PDF]
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 ...

An Automated Fault Tree Generation Approach With Fault Configuration Based on Model Checking
Fault tree generation technology is a key issue for safety analysis of large complex systems. Traditional safety analysis methods usually describe the origin, propagation, or concrete behavior of the fault and do not portray the constraints between ...

A Data-Driven Fault Tree for a Time Causality Analysis in an Aging System
This paper develops a data-driven fault tree methodology that addresses the problem of the fault prognosis of an aging system based on an interpretable time causality analysis model. The model merges the concepts of knowledge discovery in the dataset and
