针对作战编队执行长时间、远距离任务期间,编队后方保障站点变更的情况,结合部队维修保障的特点,基于可修复备件多级管理(METRIC)理论,通过计算编队剩余备件分布规律,建立了动态保障体系结构下基于时变可用度的三级两层备件保障模型。以备件储存空间为约束,可用度为目标,建立了分阶段边际优化模型。列举实例,采用分阶段边际算法对备件方案进行优化,对比分析了动态保障结构下和固定保障结构下装备可用度随时间的变化,并采用蒙特卡罗仿真方法对案例进行实验验证。案例结果表明:采取多个后方站点的保障方式能有效提高装备可用度;案例仿真实验结果与解析结果误差在4%以内。模型可为保障决策者制定备件方案提供辅助决策工具。
According to the characteristics of maintenance and repair of the fleet during the long-term and long-distance missions during the long-term and long-distance missions of the battle formation and based on the METRIC theory, the rules of remaining spare parts formation were established and the dynamic Three Level Two Level Spare Parts Assurance Model Based on Time Variable Availability under Security Architecture. Taking spare parts storage space as constraint and availability as objective, a phased optimization model was established. An example is given to optimize the spare parts plan by using the staged marginal algorithm. The changes of the equipment availability under the dynamic guarantee structure and the fixed support structure with time are analyzed. The Monte Carlo simulation method is used to verify the case. The results of the case show that adopting multiple back-site security modes can effectively improve the availability of equipment. The error between case simulation results and analytical results is within 4%. The model can provide ancillary decision-making tools for safeguarding decision makers in the formulation of spare parts.
