摘　　要：在一个供应商和一个零售商组成的供应链中,供应商允许零售商延期支付货款,而零售商则决定零售价格和库存水平。通过建立该问题的数学模型结合解析分析,在分散决策条件下,证明了零售商目标函数的性质,给出了其最优决策的求解步骤,从而证明零售商可以以不高于进货价格的零售价格销售产品。在集中决策的条件下,证明了一体化供应链目标函数的性质,给出最优商业信用期、零售价格和库存水平的决策步骤。最后,通过数值算例说明了所得结论。dConsider a supply chain consisting of a supplier and a retailer, the supplier offers a permissible delay in payments to the retailer, the ordering quantity and the retail price setting were decided by the retailer. The proper mathematical model was established, through analytical analysis, the properties of object function of the retailer was derived under the condition of decentralized channel, the solution procedure to find the optimal solution was developed, and thus proved the retailer may sell the goods at the price that is not more than the purchasing price. Upon this, the object function properties of the centralized channel was discussed analytically, also the procedures for determining the optimal trade credit period,retail price and the inventory level were provided under cooperative relationships. Finally,a numerical example is shown to illustrate the theoretical results of the proposed model.
