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.
Newsboy problem is the basic model for the study of supply chain coordination.However, most of the results are based on the risk-neutral assumption that in the real world, the rational decision maker seeks both profit and risk.We extend the supply chain coordination in a risk-neutral world , Introduces the analysis of means of mean (VAM) to explore the coordination of repurchase contracts under different risk constraints.The model shows that compared with centralized supply chain, decentralized supply chain has the function of risk diversification.In addition, it resolves the limitations of the model such as Cai Deming, That is, given the wholesale price of the repurchase price, and at the same time decided to wholesale price and repurchase price.
