Dynamic Fault Tree Models for FPGA Fault Tolerance and Reliability
2021 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2021Field Programmable Gate Arrays (FPGAs) are widely used in many safety-critical applications mainly due to their high computational efficiency and dynamic reconfiguration. Although dynamic reconfigurability is often leveraged upon to attain further flexibility and reliability, it comes with an area overhead.

Evaluation of control system reliability using combined dynamic fault trees and Markov models
International Conference on Industrial Informatics, 2015 In this paper, dynamic simulation methods for reliability evaluation of common industry-based control system architectures are investigated. Control system design often employs complex reliability structures in the forms of several levels of software and

A review on the realization methods of dynamic fault tree
Quality and Reliability Engineering International, 2022AbstractDynamic fault tree (DFT) is an extended technology of Fault tree analysis (FTA). It has been widely used in many fields and plays an important role in improving the security performance of the system. Although DFT has developed for many years, new research in recent years is still worthy of attention.

Reliability Engineering & System Safety, 2002
Abstract The fault tree analysis is a widely used method for evaluation of systems reliability and nuclear power plants safety. This paper presents a new method, which represents extension of the classic fault tree with the time requirements. The dynamic fault tree offers a range of risk informed applications.

Effective Static and Dynamic Fault Tree Analysis
2016Fault trees constitute one of the essential formalisms for static safety analysis of various industrial systems. Dynamic fault trees (DFT) enrich the formalism by support for time-dependent behaviour, e.g., repairs or dynamic dependencies. This enables more realistic and more precise modelling, and can thereby avoid overly pessimistic analysis results.

On-Line Fault Diagnosis Using Dynamic Fault Tree
IFAC Proceedings Volumes, 2001Abstract By incorporating SDG, FTA and fuzzy inference techniques, a novel framework for fault diagnosis is developed in this paper. To relieve the on-line computation load, the scope of diagnosis is limited to the fault origins leading to the top events of given fault trees. The corresponding fault propagation patterns are derived from SOG model and

Dynamic analysis of coherent fault trees
Journal of Quality in Maintenance Engineering, 1998An important characteristic of many engineering systems which cannot be modeled by fault trees to perform system reliability analysis is that they behave dynamically. In this paper, the method of applying Petri Nets (Pns) as a modeling tool to represent the coherent fault trees is discussed.

Algebraic Modeling for Dynamic Gates in Dynamic Fault Trees
Applied Mechanics and Materials, 2012This paper proposed a novel algebraic framework for modeling dynamic gates in dynamic fault trees (DFTs). The algebraic modeling of DFTs tries to avoid the ambiguities and inconsistencies of the natural languages-based original definitions. Aim to solve this issue, preliminarily a formal framework is defined, including the definitions, properties ...

Combinatorial Analysis of Dynamic Fault Trees with Priority-AND Gates
2012 IEEE 23rd International Symposium on Software Reliability Engineering Workshops, 2012This paper focuses on a sub-class of Dynamic Fault Trees (DFTs), called Priority Fault Trees (PFTs), containing only static Boolean logic gates and Priority-AND (PAND) gates. We present a transformation from a PAND gate to an AND gate with some dependent conditioning events, called CAND gate, provided that the dynamic behavior of the system can be ...
