基于定性模拟的分组多属性逆向拍卖评标行为分析

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,分组多属性评标是当今普遍采用的评标机制.针对采购招投标现状,提出了分组多属性逆向拍卖概念,在评标专家有限理性的前提下,分析了评标机制中可能存在的问题,提炼出了专家评标工作行为变化各因素及相互作用关系图,建立了影响评标专家决策的定性模型.利用定性模拟技术对评标专家对立情绪等行为进行仿真研究,进而调整不同时刻的决策变量,仿真结果表明评标专家组之间对立情绪的累积现象是明显存在的,适时采取合适的管理措施对情绪的累积有一定的减缓作用,并给出了三点改进建议,以提高评标公平性.

Bidding Evaluation Behavior Analysis of Grouped Multi-attribute Reverse Auction Based on Qualitative Simulation

Reverse auction with multi-attributes is widely used for centralized procurements of large enterprises and government,and grouped multi-attribute is the most popular mechanism at present.Based on the current situation about bidding,the concept of grouped multi-attribute auction was proposed at first.Taking the bounded rationality of the bidding evaluation experts into consideration,some existing problems about the current mechanism were analyzed,and the relational graph of bidding evaluation behaviors about bidding experts was presented.Meanwhile,the qualitative model,which could influence the decision-making behavior of bidding evaluation experts,was established.The antagonistic feelings of two groups were studied by means of qualitative simulation(QSIM) and then the decision variable of different moments could be adjusted.Some significant results about the behavioral analysis have been obtained.And the simulation results indicated the effectiveness of this method.Because of the different benefit and responsibility,it is easy to bring about the accumulation of antagonistic feelings.As the difference increases,objectiveness becomes worse and worse.In the end,three improved suggestions were proposed.In further study,it will be a key point to improve and optimize the current mechanism of GMAA.
