For mission‐critical or safety‐critical systems, redundancy techniques are often applied to
satisfy the stringent reliability requirements of the system design. Warm standby sparing is a …

The process industry has always been faced with the challenging task of determining the
overall unavailability of safeguarding systems such as the safety instrumented systems …

Mode transfers have attracted attention from the standby system community as they can
effectively reduce system downtime. However, the existing models are not applicable to …

Mission abort is an effective way to enhance system safety during mission execution.
Existing multi-attempt mission abort models can be divided into two main categories …

Mission success is an important criterion to measure the performance of phased-mission
systems, which is the ability of systems to finish the work successfully. Activating the spare …

Abstract Systems that have multiple consecutive and non-overlapping phases of operations
during their missions are referred to as phased-mission systems (PMSs). Previous research …

For the mission-oriented systems, it is not feasible to do any preventive maintenance when
the mission is executing. However, the replacement time obtained by traditional replacement …

While the majority of existing works on modeling and optimizing standby systems focus on
single-phased missions, only a few works consider standby systems with phased-mission …

The paper considers heterogeneous 1-out-of-N warm standby systems when all
components can experience internal failures whereas operating components are exposed to …

Active redundancy is an effective technique for improving the mission success probability.
However, more components simultaneously performing the mission implies higher cost and …
