This paper considers the optimal choice of productivity (load) of components in 1-out-of-N
non-repairable cold standby systems. It is assumed that each system component can …

This paper considers the modelling and optimization of 1-out-of-N: G cold standby (CS)
systems with non-repairable components functioning at different levels of productivity or …

This paper investigates the heterogeneity of components with proportional hazard rates in a
redundant system. The total number of those standbys surviving the failure time of some …

It is well recognized that using the hot standby redundancy provides fast restoration in the
case of failures. However the redundant elements are exposed to working stresses before …

Warm standby redundancy has been used as an effective design technique for improving
the reliability of a system while achieving the compromise between restoration cost and …

In standby systems, when an online working element fails, a replacement procedure is
initiated to activate a standby unit which will take over the mission task to sustain the system …

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 …

An n-unit system provisioned with a single warm standby is investigated. The individual units
are subject to repairable failures, while the entire system is subject to a nonrepairable failure …

We study the availability analysis of three different series system configurations with warm
standby components and general repair times. The time-to-failure for each of the primary …

This paper considers nonrepairable 1-out-of-N: G cold standby (CS) systems subject to
uneven backup actions as well as dynamic backup and retrieval times. In such systems, only …
