多等级供应模式下鱼雷武器备件补给策略优化

Supply Policy Research on Optimization for Spares Based on Multi-Echelon Supply Mode

备件是影响装备战备完好能力及任务持续能力的重要因素。考虑备件的可靠性、价格等因素,根据多级供应模式,提出了(S-X,S)备件累计消耗量补给策略;利用Gamma等效评估算法,建立了备件补给保障效果使用可用度评估模型和仿真模型,通过实例对模型与(S-1,S)补给策略进行了验证与比对。仿真结果表明:对多站点而言,相比较(S-1,S)备件补给策略的"强者愈强、弱者愈弱"马太效应,(S-X,S)备件补给策略具有"劫富济贫"的特点。

Spares is one of the important factor of the operational readiness and the mission success.The paper provides the spares＇ accumlative consumption supply policy of（S-X,S）based on the multiehcelon supply mode according to spares＇ reliability and price,then the operational availability evaluation model and simulation model are set up based on Gamma equivalent evaluation arithmetic,and then the model is validated and compared with（S-1,S） supply policy. Simulation results show that（SX,S）spares supply policy has the feature of＂robbing the rich and helping the poor＂compared with（S-1,S）supply policy＇s the Matthew Effect of＂the stronger the stronger,the weaker the weaker＂.
