A dynamic fault tree

Reliability Engineering and 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.

A methodology of alarm filtering using dynamic fault tree

Reliability Engineering and System Safety, 2011
This article presents a new approach for filtering the faults, thanks to the defined dynamic fault tree (DFT). The proposed methodology includes the dependencies between fault events in the models. Two problems must thus be solved: they relate to the filtering of false alarms, and the reduction of the size of the ambiguity of fault isolation related to

Dynamic fault-tree models for fault-tolerant computer systems

IEEE Transactions on Reliability, 1992
Reliability analysis of fault-tolerant computer systems for critical applications is complicated by several factors. Systems designed to achieve high levels of reliability frequently employ high levels of redundancy, dynamic redundancy management, and complex fault and error recovery techniques.

Dynamic Fault Tree Models for FPGA Fault Tolerance and Reliability

2021 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2021
Field 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.

A review on the realization methods of dynamic fault tree

Quality and Reliability Engineering International, 2022
AbstractDynamic 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.

Dynamic Fault Tolerance in Fat Trees

IEEE Transactions on Computers, 2011
Fat trees are a very common communication architecture in current large-scale parallel computers. The probability of failure in these systems increases with the number of components. We present a routing method for deterministically and adaptively routed fat trees, applicable to both distributed and source routing, that is able to handle several ...

Dynamic Reliability Block Diagrams VS Dynamic Fault Trees

2007 Proceedings - Annual Reliability and Maintainability Sympsoium, 2007
Reliability block diagrams (RBD), and fault trees (FT) are the most widely used formalisms in system reliability modeling. They implement two different approaches: in a reliability block diagram, the system is represented by components connected according to their function or reliability relationships, while fault trees show which combinations of the ...
