Life critical applications like space missions and flight controls require their computing
systems to be equipped with some fault-tolerance mechanism to meet stringent reliability …

Cold standby redundancy is a widely-applied design strategy to achieve high system
reliability in numerous applications. To facilitate an effective system recovery in case of an …

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 …

In this paper, mission reliability, expected mission completion time, and cost of non-
repairable 1-out-of-N: G warm standby sparing systems subject to uneven backup actions …

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 …

Reliability modeling and optimization of warm standby systems have attracted considerable
research attentions in the past decade due to their wide use in diverse critical applications …

This paper models a real-time warm standby system that has to accomplish a specified
amount of task by a hard deadline. The system is subject to corrective replacements (CRs) …

In this paper we model and analyze non-repairable 1-out-of-N: G warm standby systems
subject to periodic backups and dynamic reworking. Particularly, in such systems, a standby …

This paper models a warm standby system where a single element is online performing a
specified mission task (eg, a computing task) and subject to corrective replacement (CR) by …

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 …
