INCLUDING SYSTEMATIC FAULTS INTO FAULT TREE ANALYSIS [PDF]
IFAC Proceedings Volumes, 2006 : Fault Tree Analysis (FTA) is a technique widely used for fault forecasting of physical systems. Although FTA is considered a well established safety analysis technique, paradoxically classical Fault Trees include only random faults. However, in modem automated systems, undesirable events arise not only from random hardware faults but also from ...

An Automated Fault Tree Generation Approach With Fault Configuration Based on Model Checking
IEEE Access, 2018 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 ...

Parametric Analyses of Attack-Fault Trees [PDF]
2019 19th International Conference on Application of Concurrency to System Design (ACSD), 2019 Risk assessment of cyber-physical systems, such as power plants, connected devices and IT-infrastructures has always been challenging: safety (i. e., absence of unintentional failures) and security (i. e., no disruptions due to attackers) are conditions that must be guaranteed.
