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 …

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 …

This paper considers single-component repairable systems supporting different levels of
workloads and subject to random repair times. The mission is successful if the system can …

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 …

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 …

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 …

This paper considers single-component repairable systems performing backup procedures
to avoid repeating the entire work from scratch and thus facilitate fast system recovery in the …

Catastrophic failures of safety-critical systems could result in irretrievable economic losses
and damage. To enhance the survivability of safety-critical systems, a mission can be …

Mission-oriented systems have received intensive attention for extensive applications.
Existing maintenance policies focus mainly on unvarying missions, which is inconsistent …

This paper studies selective maintenance for multi-component systems that undergo
consecutive missions with scheduled breaks after each mission. To increase the likelihood …
