Phased-mission systems widely exist in many real-world systems such as communication
networks, aerospace and unmanned aerial vehicles. The reliability modeling and analysis of …

Redundancy or standby is a technique that has been widely applied to improving system
reliability and availability in the stage of system design. In this paper, we consider a standby …

Standby redundancy is a common and fundamental technique for increasing the reliability
and availability of various systems. Cold-standby state is one of the most important …

This paper considers a framework to optimally design a maintainable cold-standby system.
Not only the maintenance policy is to be determined, but also the reliability character of the …

Standby redundancy is a design technique that has been widely adopted to enhance system
reliability and achieve fault tolerance in many critical applications. In this paper, we consider …

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 …

Redundancy or standby is a technique that has been widely applied to improving system
reliability and availability in system design. In most cases, components in standby system …

The optimal activation order (OAO) is introduced as a new concept in reliability optimization
problems (ROPs), which sharply contrasts with the conventional redundancy strategies …

Safety-critical systems have been widely applied in various practical engineering fields to
perform specific missions. Failures of such systems will lead to significant damage, thus …

Redundancy allocation problem (RAP) is a common technique for increasing the reliability
of systems. In this paper, a new model for the RAP is introduced that takes into account the …
