Summary: In the existing studies, the positive effects of protective devices on the reliability of balanced systems have been overlooked. This paper proposes two reliability models for balanced systems with multi-state protective devices from the perspectives of dynamic and static balanced concepts. The models consider new triggering and protection mechanisms based on the characteristics of the balanced systems. The reliability of the proposed models is derived using the Markov process embedding method combined with Monte-Carlo simulation, and the practical engineering applications validate the applicability of the proposed systems and correctness of the method.

Summary: Recent studies have shown that reusing standby elements during the mission can significantly improve mission success probability. This paper contributes by modeling and optimizing the replacement and maintenance schedule (RMS) for a dual-unit warm standby system to minimize total expected mission cost, considering operation, standby, maintenance costs, and mission failure penalty cost. The proposed probabilistic model-based methodology assesses mission success probability and expected mission cost, with an optimization problem formulated to find the optimal RMS solution.
