Towards an Accurate Probabilistic Modeling and Statistical Analysis of Temporal Faults via Temporal Dynamic Fault-Trees (TDFTs) [PDF]
IEEE Access, 2019 Fault tree (FT) is a standardized notation for representing relationships between a system's reliability and the faults and/or the events associated with it.

A Method for Temporal Fault Tree Analysis Using Intuitionistic Fuzzy Set and Expert Elicitation [PDF]
IEEE Access, 2020 Temporal fault trees (TFTs), an extension of classical Boolean fault trees, can model time-dependent failure behaviour of dynamic systems. The methodologies used for quantitative analysis of TFTs include algebraic solutions, Petri nets (PN), and Bayesian

Compositional Synthesis of Temporal Fault Trees from State Machines [PDF]
ACM SIGMETRICS Performance Evaluation Review, 2011 Dependability analysis of a dynamic system which is embedded with several complex interrelated components raises two main problems. First, it is difficult to represent in a single coherent and complete picture how the system and its constituent parts behave in conditions of failure.

Dependability Analysis Using Temporal Fault Trees and Monte Carlo Simulation
Advances in Intelligent Systems and Computing, 2021 The safety and reliability of high-consequence systems is an issue of utmost importance to engineers because such systems can have catastrophic effects if they fail. Fault Tree Analysis (FTA) is a well-known probabilistic technique for assessing the reliability of safety-critical systems. Standard FTA approaches are primarily static analysis techniques

Qualitative temporal analysis: Towards a full implementation of the Fault Tree Handbook [PDF]
Control Engineering Practice, 2009 The Fault Tree Handbook has become the de facto standard for fault tree analysis (FTA), defining the notation and mathematical foundation of this widely used safety analysis technique. The Handbook recognises that classical combinatorial fault trees employing only Boolean gates cannot capture the potentially critical significance of the temporal ...

Quantitative evaluation of Pandora Temporal Fault Trees via Petri Nets
IFAC-PapersOnLine, 2015 Abstract Using classical combinatorial fault trees, analysts are able to assess the effects of combinations of failures on system behaviour but are unable to capture sequence dependent dynamic behaviour. Pandora introduces temporal gates and temporal laws to fault trees to allow sequence-dependent dynamic analysis of events.

Functional safety analysis of safety-critical system using state transition diagram
Радіоелектронні і комп'ютерні системи, 2022 The subject of research is to determine the functional safety indicators of a fault-tolerant safety-critical system, namely, the minimal cut sets’ probability for a given duration of the system’s operation, using the state transition diagram (STD).
