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 …

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 …

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 …

Intensive research efforts have been dedicated to reliability analysis and optimization of
standby systems. However, only few of the existing models allow a system element to be …

Traditional standby system models have mostly assumed that each element can be online
and used once during the mission time. In practice especially when a long mission task is …

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

In many industrial and technological systems, due to factors such as deterioration, corrosion,
attacks, etc., preventive replacement is typically performed according to a predetermined …

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) …

For some critical applications, successfully accomplishing the mission or surviving the
system through aborting the mission and performing a rescue procedure in the event of …

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 …
