多属性逆向拍卖分组评标行为的实验研究

网络逆向拍卖已经成为政府和大型企业集团集中采购的重要途径,分组多属性拍卖是当今普遍采用的评标机制.构建了分组多属性逆向拍卖评标的数学模型,在评标专家有限理性的前提下预测该机制下可能存在评标专家组间对立情绪累积问题.借鉴实验经济学模拟与仿真、行为分析方法,在定义抬标、压标行为参数的基础上,利用学生评标实验数据,验证了当前机制确实存在情绪累积效应,提出增设综合专家组和标书中分组属性的信息相互开放等改进新机制,并通过角色实验比较其优越性.进而提出3点改进建议,利用多Agent技术进一步研究多属性逆向拍卖评标行为是下步工作.

The Experimental Study of Grouped Bid Evaluation Behavior about Multi-Attribute Reverse Auction

Reverse auction with multi-attributes is widely used for centralized procurements of large enterprises and government,and the bid evaluation of grouped multi-attribute is the popular mechanism at present.The mathematical model about evaluation of bid of grouped multi-attribute is structured first.Taking bounded rationality as precondition,we forecast the existence about the accumulation of antagonism by means of bid evaluation experiments.And then take example by simulation and behavioral analysis methods of experimental economics,based on the definition of behavioral parameters,we get the conclusion that the accumulation of antagonism exists surely through the analysis of experimental data.At last,we suggest:To set a group of integrative experts and some criteria related with two groups of attributes,and open both technical and business criteria to opposing groups.Based on the experimental data,The comparison and analysis about the three mechanisms are given.Meanwhile three improved proposals are raised.In further study,it is a key point to study the bidding evaluation behavior making use of the multi-agent technology.
