报童问题是研究供应链协调的基本模型.可是,多数结果都是基于风险中性的假定.在现实世界中,理性决策者既寻求利润又关注风险.我们扩展了风险中性世界中供应链协调的概念,引入均值方差分析,探索不同风险约束下回购合同的协调问题.模型显示与集中供应链相比,分散供应链却具有分散风险的作用.另外,解决了蔡德铭等模型的局限性,即在给定批发价格下求解回购价格,而做到了同时决定批发价格和回购价格.

The newsvendor problem is a basic model in studying supply chain coordination.However, most of the results are grounded on the assumption of risk-neutral agents. Rational decision makers in the real world both seek profit and reduce risk. The conception of supply chain coordination in the risk-neutral world was extended, the mean-variance analysis was introduced and the newsvendor problem was explored, which involves the coordination by buyback contracts under different risk constraints. The model indicates that decentralized supply chain has the function of diversifying risk in comparison with centralized supply chain. In addition, we simultaneously get the solution about wholesale price and buyback price, thus extend Choi's model.
