两层供应商的选择和协商策略研究

供应商选择是建立供应链合作伙伴关系的一项重要内容。本文在现有文献的基础上对供应商选择模型进行了改进，建立一个两层供应商选择混合整数规划模型，在模型中增加考虑了供应商的供应商的绩效水平。供应商选择决策会导致一些参与竞争的供应商落选，为了保持对被选供应商的竞争力，文章建立了一个协商策略模型，来确定那些未被选中的供应商若想被选中所需要达到的业绩水平。

Two-stage Vendor Selection and Negotiation Strategy

Vendor selection is an important component in developing supplier chain partnership. This paper improves the model of vendor selection based on present literature and develops a mixed-integer programming model for two-stage vendor selection, in which the performance levels of vendor＇s vendor will be considered. The vendor selection problem implies that some competing vendors will not be employed. This paper develops a negotiation model to identify performance levels which non-selected vendors must attain in order to be competitive with the selected vendors.
