Warm standby redundancy is a fault-tolerant technique balancing the low economical
efficiency of hot standby and the long recovery time of cold standby. In this paper, motivated …

In any redundant system, the state of the standby unit is usually taken to be hot, warm or
cold. In this paper, we present a new model of a two unit standby system wherein the …

Traditional standby system models predominantly assume that a standby unit is activated
only after an active unit fails. However, a periodic active switching policy is adopted for some …

In many industrial and technological systems, due to factors such as deterioration, corrosion,
attacks, etc., preventive replacement is typically performed according to a predetermined …

In the past, redundancy, inventory and maintenance are often considered separately to
improve the system availability. Recently, a few joint optimization papers have emerged, but …

A new methodology for the reliability optimization of ak dissimilar-unit nonrepairable cold-
standby redundant system is introduced in this paper. Each unit is composed of a number of …

For a repairable k-out-of-n: G system consisting of line-replaceable units, its operational
availability depends on component reliability, its redundancy level, and spare parts …

This paper models and optimizes dynamic performance of multistate systems with a general
series parallel structure. Each system component is a 1-out-of-N warm standby configuration …

This article models and analyzes the reliability of warm-standby systems subject to imperfect
fault coverage based on sequential multistate decision diagrams. For warm-standby …

Many real-world systems are heterogeneous k-out-of-n cold standby systems, like
unmanned aerial vehicles performing a reconnaissance mission along multiple routes …
