多属性密封拍卖模型及最优投标策略

Multi-attribute sealed-bid auction model and optimal bidding strategies

针对当前传统的基于单一价格属性的逆向拍卖机制已难以满足企业日益复杂的采购需求的现状,研究采购环境下的多属性密封拍卖机制.首先,在指出现有多属性拍卖模型缺陷的基础上,提出了更符合现实需求的改进多属性拍卖模型.然后运用多属性效用理论,进一步研究了密封拍卖机制下投标人的最优投标策略,特别地,证明了投标人非价格属性确定的一个重要推论.最后,对模型参数对最优投标策略的影响进行了分析.

Today more and more enterprises procured the goods and services based on reverse auction mechanisms. But the traditional price-based single attribute auction mechanisms had not satisfied the practical demand. In view of this situation, we studied the multi-attribute sealed-bid auction mechanism in procurement environment. First, we proposed an improved multi-attribute auction model based on the limitation of the existed models, and then we further studied the bidders＇ optimal bidding strategies in sealed-bid auction mechanism based on multi-attribute utility theory （MAUT）. In particular, we proved an important inference which can be used to determine the non-price attributes. At last, we analyzed the influence of the model parameters on the optimal bidding strategies.
