K:N系统可修复备件两级供应保障优化研究

Research on two-echelon supply support optimizing for repairable spare parts of K:N system

备件供应保障优化是提高武器装备的战备完好性和降低寿命周期费用的重要途径。通过分析复杂装备可修复备件两级供应保障系统,研究了备件保障与装备战备完好性的关系,建立了以备件购置费用为约束、系统供应可用度最大为目标的冗余度系统可修复备件供应保障优化模型,并运用边际效能法进行求解。实例应用证明,模型可以优化备件库存以及评估备件库存量、两级维修能力、系统自身可靠性等因素对系统保障效能的影响。

Supply support optimizing is an important approach to improve operational readiness and reduce life cycle cost for equipments.Through analyzing the two-echelon supply support system for repairable spare parts of complex equipment,and researching the relationship of spare parts support and operational readiness,a supply support optimizing model is proposed,which chooses system supply availability as the object and the total acquisition cost as the subject.Marginal efficiency analysis algorithm is applied to achieve the optimization.Finally,several examples are given to verify that this model can optimize spare parts storage,and evaluate the effects on support efficiency of some important factors,including different stock,repair capacity of two levels,reliability and so on.
