战时任务条件下舰艇装备多级备件优化

Optimization of Warship Spare Parts in the Scenario of Wartime Mission

战时舰艇装备通常为三级备件维修保障体制和四级备件供应保障模式,各级备件库存是影响舰艇编队任务持续能力的重要因素.在分析编队作战任务过程和备件保障流程基础上,对动态帕尓姆定理进行了扩展,使其适用于车间可更换单元(SRU)在修件数概率分布计算.综合考虑战时动态任务、装备的自然故障和战损故障、备件的报废和采购等因素,建立了战时备件维修和供应保障模式下的舰艇编队任务成功性评估模型.以备件保障费用为目标函数,舰艇编队任务成功性为约束条件,建立了基于舰艇编队任务成功性的备件库存优化模型,并运用边际效应方法对该优化模型进行求解.实例运算表明,该模型可以为战时各舰艇装备保障单位制定保障方案提供一定的决策支持.

Warship equipment is always supported by three-echelon spare parts maintenance support an, four-echelon spare parts supply support system in wartime. Inventory is an important factor to brigad sustainability. Combat mission and spare parts support system was analyzed. By extending dynamic Palr theorem, probability distribution of SRU in repair can be computed. Dynamic mission, failure, comba damage, condemnations and procurement were considered and brigade mission success evaluation model bl spare parts maintenance and supply support in wartime was established. Stock cost was taken as the opti mization object and brigade mission success was used as the restriction. Spare parts optimization mode based on brigade mission success was established. The spare parts optimization concept was provided base on margin analysis method. Finally, it was illuminated that the model would provide decision-making {o equipment support units in designing support concept.
