动态市场环境下基于收益共享契约的供应链协调模型

A Supply Chain Coordination Model in the Dynamic Markets based on Revenue Sharing Contract

在动态市场环境下,探讨了由单个制造商和单个零售商所组成的两层供应链的订货协调问题。利用了一个两阶段Newsboy模型来刻画零售商的两次订购行为。在假定第1阶段未满足需求部分延期供给的情形下,分别建立了集中决策和分散决策模型,并分别证明了这2个模型解的存在唯一性。提出了一个两阶段的收益共享契约以实现供应链的协调,该契约不但简单而且容易实施。研究发现:与短缺量完全损失相比,部分短缺量延期供给将导致零售商减少第1阶段订购量而增加第2阶段订购量,但零售商在2个阶段的总订购量将增加。

This paper studies the coordination issues of a two-echelon supply chain with a single manufacturer and a single retailer in a dynamic market.A two-period newsboy model is employed to depict the retailer＇s behavior in two-time ordering.Under the assumption that the unfilled demand during the first period is partial backlogging,the centralized and decentralized decision models are developed,respectively,and the existence and uniqueness of the optimal solutions to the two models are proved.Moreover,a two-period revenue-sharing contract,which is simple and easy to implement,is proposed to achieve the supply chain coordination and win-win outcome.The research shows that compared with the case of no backlogging,the partial backlogging results in decrease of the order quantity in first period but the increase of the order quantity in the second period,whereas overall the total order quantity increases.
