This article discusses the problems associated with the redundancy of structures k-out-of-n
as a method of increasing system availability. A parallel k-out-of-n system was considered …

In many real production systems, a system may be stopped due to a lack of demand or
exhaustion of raw materials. This is known as production wait and provides a good …

This paper models a dual-unit standby system with non-identical, reusable units that perform
the mission task alternatively according to a pre-specified replacement and maintenance …

Redundancy is widely applied in modern airborne systems. Operation with faults in
redundant airborne systems can improve the dispatch reliability of aircraft and reduce …

Due to its capacity to increase system reliability, cold standby redundancy design has
attracted considerable attention and has been applied in crucial-safety engineering systems …

Recent studies have shown that elements reusing through preventive replacements is
beneficial in enhancing the mission success probability (MSP) of standby systems. While …

Recent studies have shown that reusing standby elements during the mission may improve
the mission success probability significantly. However, such a benefit cannot be effectively …

Traditional reliability models typically assume that a system can operate until it is failed or
not needed due to the mission completion. In practice, the system may have limited resource …

Resilience is an important property in many engineering systems that may be exposed to
shocks. Existing resilience measures primarily focus on changes in system performance …

This paper models and optimizes the replacement and maintenance schedule (RMS) for a
heterogeneous two-unit standby system. The system must accomplish a specified amount of …
