摘　　要：研究报童模型双周期下决策者面临服务水平的机会约束时,所做出的最优决策.通过构建模型,分析了该模型的最优订货决策和最优目标函数的解析解.在数值分析中,对模型中的参数做了相应的灵敏度分析.最后,将该模型和文献中的单周期带服务水平约束的报童模型进行了对比.分析了在2种不同的模型下,参数变化给模型的目标值和最优解带来的影响.This paper discussed the single buyer＇s optimal purchasing decision in two-period when facing opportunity constraints of service level.By constructing a model,the optimal ordering policy and the analytical solution to the optimal objective value were proposed.Numerical analysis was conducted of the parameters in the model.Meanwhile,a comparison was made between the proposed model and the single period news-vendor problem with service level constrain in the literature.Finally,the impacts of the variation of parameters of these two models on optimal objective value and solution were analyzed.
