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.
