A methodology of alarm filtering using dynamic fault tree
Reliability Engineering & System Safety, 2011This 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

Siamese-Twin: A Dynamically Fault-Tolerant Fat-Tree
19th IEEE International Parallel and Distributed Processing Symposium, 2005Fat-trees are a special case of multistage interconnection networks with quite good static fault tolerance capabilities. They are however straightforwardly unable to provide local dynamic fault tolerance. In this paper we propose a network topology based on the fat-tree using two parallel networks with crossover links between them in an effort to ...

Galileo: A Tool for Dynamic Fault Tree Analysis
2000Galileo is a prototype software tool for dependability analysis of fault tolerant computer-based systems. Reliability models are specified using dynamic fault trees, which provide special constructs for modeling sequential failure modes in addition to standard combinatorial fault tree gates.

Dynamic fault-tree models for fault-tolerant computer systems
IEEE Transactions on Reliability, 1992Reliability 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.

Design of Dynamic Systems Based on Dynamic Fault Trees and Neural Networks
2006 IEEE International Conference on Automation Science and Engineering, 2006Reliability design of static systems has been widely developed in recent years. Fault trees (FT), genetic algorithms (GA) and neural networks (NN) are among the most common methodologies used in such tasks. However, because of the complex behavior of dynamic systems, less attention has been paid on their design.

Dependability Evaluation with Dynamic Reliability Block Diagrams and Dynamic Fault Trees
IEEE Transactions on Dependable and Secure Computing, 2009Dependability evaluation is an important often-mandatory step in designing and analyzing (critical) systems. Introducing control and/or computing devices to automate processes increases the system complexity, with an impact on the overall dependability.

Fault diagnostics of dynamic system operation using a fault tree based method
Reliability Engineering & System Safety, 2009For conventional systems, their availability can be considerably improved by reducing the time taken to restore the system to the working state when faults occur. Fault identification can be a significant proportion of the time taken in the repair process.
