摘　　要：针对价格适中、消耗量高、对装备运行起重要作用的不可修备件的库存管理问题,构建了碳税政策下由多个基层站点和一个基地站点组成的两级保障链联合库存决策模型。模型以基层站点再申请点ri、申请量Qi和基地站点补给次数mi为决策变量、以备件满足率为约束、以成本为目标。最后通过策略迭代方法对模型求解,并在数值分析中研究碳税对保障链决策的影响,结果表明:碳税政策虽然增加了保障链成本,但减少了碳排放,并且在合理的税费下能够实现显著的减排效果,有助于环境成本的降低。Spare parts inventory management is a very important work in equipment support engineering,and the classical METRIC theory is proposed for repairable spare parts with high price and low demand rate,and such spare parts usually adopt(S-1,S)inventory strategy.However,for non-repairable spare parts with moderate price,high consumption and important role in equipment operation,the inventory strategy of continuous inspection(S-1,S)is no longer applicable,and this kind of spare parts is more suitable to adopt(r,Q)inventory strategy.On the other hand,under the carbon tax policy,the spare parts support unit has to adjust the ordering strategy to achieve emission and cost reduction.Therefore,under the two-echelon support chain consisting of multiple grassroots stations and one base station,we conduct joint optimization on the ordering strategy of each station,and analysis the impact of carbon tax policy on the ordering decision of support chain.In this paper,it is assumed that the demand for spare parts is subject to Poisson distribution;the grassroots station i implements(ri,Qi)inventory strategy and the lead-time is Li;the base station implements(T0,Q0)inventory strategy and the lead-time is L0.With such assumptions,the spare parts ordering models of grassroots-level and stations are firstly constructed respectively.Then,the joint order model is obtained by combining the separate models together,and the model takes grassroots station reorder point ri,order quantity Qi and base station replenishments times mi as decision variables,takes spare parts satisfaction rate as constraint,and takes expected cost as target.Finally,the model is solved by the policy-iteration algorithm,and the influence of carbon tax on support chain decision is studied in the numerical analysis.The numerical analysis results show that the results of the influence of the lower limit of spare parts satisfaction rate to the decision of the support chain are consistent with the actual situation,thus the correctness and feasibility of the model are veri
