摘　　要：分销系统的库存问题研究是物流及供应链管理理论研究的重要方面,有关策略的使用影响到相关供应链整体的成本和收益,为此基于基本库存策略,研究了随机需求条件下一个分销中心和多个零售商组成的二级分销系统的协同库存和订货问题.对分销中心库存的补充订货、缺货处理以及分销系统各成员之间的关系等问题采取协同策略,建立了使分销系统期望总收益最大化的数学模型,在分析模型解的存在性的基础上,探索了相应的求解方法.并对均匀分布、指数分布和正态分布的3种需求情况在模型求解方面做了具体分析和实证研究.Inventory study in distribution system is a very important aspect of logistics and supply chain management theory research, and adoption of some policies may influence the cost and income of whole supply chain. Some issues on the coordinated inventory and ordering policies in two-level distribution system with stochastic demand composing of a single distribution center and multi-retailer are discussed, in which distribution center takes base-stock policy and deals in multiple products. By taking coordinated policies on some issues, such as supplement of inventory, treatment of out-of-stock and relationship among members of distribution system, a mathematical model to maximize total expected system profit is developed. Based on the analysis of the existence of solutions of the model, corresponding solution methods are explored. Also, three demand cases such as uniform distribution, exponential distribution and normal distribution are detailedly analyzed and demonstrated in solution of models.
