Optimal Load-Level Adjustment Policy for Balanced Systems in Shock Environment
研究了冲击环境下平衡系统的最优负载调整时机，提出基于组件状态信息的动态调整策略，以最小化平均成本率，并通过电压调节器案例验证了有效性。
Balanced systems refer to a class of system architectures composed of multiple components with similar or synergistic functions, whose normal operation depends on the coordination between the components in terms of position, quantity, states, etc. The reliability analysis and load level adjustment policies for balanced systems are vital for ensuring stable operations. Existing research predominantly focuses on the reliability modeling of the dependence between load levels and degradation, and there is a notable gap in optimizing load level adjustment policies that take system condition information into account. This paper addresses this gap by examining the optimal timing for load level adjustments for balanced systems in shock environments, aiming to minimize the average cost rate. We propose a condition-based load level adjustment policy that leverages component state information. Specifically, the load level of a component is dynamically adjusted in response to the number of shocks, thereby significantly enhancing the system's performance and reliability. Our study delves into the system reliability and optimization of load level adjustment policies. A comprehensive numerical example using a voltage regulator system is presented to demonstrate the proposed policy's effectiveness. To ensure the rigour of our research, we perform extensive robustness checks. The results demonstrate that the proposed policy remains robust and effective even under significant environmental stochasticity, providing a reliable decision-support tool for engineering managers.
