【摘要】：本文针对网上在线销售易逝品的无缺陷退货现象,考虑了供应链的最优订购协调问题。利用一个两阶段动态规划来描述动态市场环境下网上销售商的两次订购行为,在假定在两个销售阶段都发生无缺陷退货现象的前提下,分别建立了集中和分散决策模型,同时设计了价格保护契约以实现供应链的协调运作。最后,利用数值仿真得出了一些重要的管理启示。通过研究发现:(1)当不确定性较大时,网上销售商需要在第1阶段多订购产品以应对需求风险,因此导致了较低的系统期望利润。并且,需求的不确定性越大,供应链协调越有价值。(2)当第1阶段或第2阶段退货率或两阶段退货率都增加时,两个阶段的最优订购量均减小。(3)对于需求波动性较高的产品,顾客的退货率越小或者可服务退货率越大,价值越高(即对供应链系统期望利润的提高越显著)。
[Abstract]:In this paper, the problem of optimal ordering coordination in the supply chain is considered, and a two-stage dynamic programming is used to describe the two-time ordering behavior of the online sellers in the dynamic market environment. Based on the assumption that there is no defect return in both stages of sales, the centralized and decentralized decision models are established, and the price protection contract is designed to realize the coordinated operation of the supply chain. By using numerical simulation, some important management implications are obtained. Through research, we find that when uncertainty is high, online vendors need to order more products in stage 1 to cope with demand risks. This results in lower system expected profits. And, the greater the uncertainty of demand, the more valuable supply chain coordination is.) when the return rate of stage 1 or stage 2 increases, or the rate of return in both phases increases, For the products with high demand volatility, the lower the return rate of customer or the greater the return rate of serviceable goods, the higher the value (that is, the higher the expected profit of supply chain system is).
