This paper presents the results obtained in a continuing investigation of fault-tolerant computing which is being conducted at the Jet Propulsion Laborator\'. Initial studies led to the decision to design and construct an experimental computer with dynamic (standby) redundancy, including replaceable subsystems and a program rollback provision to eliminate transient errors. This system, called t...

Redundancy or standby is a provision which plays an important role in improving the reliability of engineering systems. This investigation deals with the reliability and sensitivity analysis of a repairable system (consisting of hardware and software components) with warm standbys and switching failures. The failure and repair rates of the components are assumed to follow exponential distributi...

Fault tree analysis is a well-known method for reliability and safety assessment of engineering systems. In the last 3 decades, a number of methods have been introduced, in the literature, for automatic construction of fault trees. The main difference between these methods is the starting model from which the tree is constructed. This paper presents a new methodology for the construction of sta...

In this study, we consider the stress-strength reliability and mean remaining strength of a series system with cold standby redundancy at component levels. Classical Bayesian approaches are studied in order to obtain estimates when underlying stress, components follow exponential distribution different parameters. Bayes approximated by using Lindley’s approximation Markov Chain Monte Carlo meth...

The redundancy allocation problem (RAP) is one of the most commonly used approaches for improving reliability systems. present study investigates recent variant RAP, namely, RAP with heterogeneous components under mixed strategy. An exact branch-and-price (BP) algorithm proposed that solves in less than CPU second all benchmark instances reported literature. not only first a strategy but also a...

<p style='text-indent:20px;'>Redundancy allocation problem (RAP) is a common technique for increasing the reliability of systems. In this paper, new model RAP introduced that takes into account warm standby and mixed strategy, dynamics, type strategy in redundancy problems. A recursive formula first obtained function dynamic strategies leverages success mode analysis works any arbitrary f...

This study focuses on effectively designing reliable systems. Such systems are capable of withstanding failure events by applying multiple realistic workarounds. These workarounds include allocating redundancy, component reliability, and backup strategy that considered concurrently as decision variables. In this novel view, the reliability components determined freely independently to achieve o...

While technology scaling increases density and near threshold voltage operation slashes energy consumption, serious reliability concerns such as radiation-induced soft errors and timing violations due to Process Variation (PV) become exacerbated. For instance, the probability of single upsets, and more realistically, multiple upsets, is projected to increase several fold at sealevel for sub-10n...
