无维护下极低使用占空比装备贮存使用阶段备件配置优化

针对当前舰艇装备备件配置均按常用装备、未考虑极低使用占空比装备不工作期间失效的不合理情况,对极低使用占空比装备不使用期间因部件故障对任务期间备件配置影响展开了研究。通过引入虚拟站点,将装备不使用期间等效转换为装备使用期间的状态,以装备可靠度为指标,建立了任务期间装备贮存使用的可靠度模型。以装备可靠度为约束,基于边际优化算法建立了舰艇装备备件配置优化模型；并依据备件保障流程,基于蒙特卡罗方法搭建了仿真模型。通过案例分析可知:对于极低使用占空比装备,考虑装备不使用期间部件失效的备件比不考虑装备贮存失效的备件要多,且模型的正确性通过仿真方法得到验证。模型可为舰艇上极少使用、长期贮存的装备制定备件方案提供参考。

Spare parts allocation optimization for extremely low duty equipment storage and use stage#br#

In view of the unreasonable situation of the equipment spare parts allocation according to the common equipment and the use of duty equipment, the failure of the equipment does not work during the period of failure, and the influence of spare parts on the spare parts allocation during the mission is studied. By introducing a virtual site, the equipment is converted from a period of no use to a condition during the use of the equipment. The reliability model of equipment storage and use during the mission is established based on the reliability of equipment. The optimization model of equipment spare parts configuration is established based on the marginal optimization algorithm with the constraint of equipment reliability. According to the support flow of spare parts, a simulation model is built based on the Monte Carlo method. Analysis of cases shows that for equipment of very low use ratio, spare parts that consider equipment used during component failure are more than those without considering equipment storage failure, and correctness of the model is verified by the simulation method. The model can be used as a reference for the plan making of spare parts to be developed and used in a ship for a long period of time.
