基于双向交叉评价的投标方排序模型

An Outranking Model of Bidirectional Cross Evaluation for Contractor Selection

本文提出基于双向交叉评价的投标方排序优选模型用于承包商选择决策支持。模型以竞争性双向交叉评价矩阵生成的被动他评值和主动评他值信息,结合熵权-TOPSIS方法,分析投标方综合绩效指数,并进一步结合投标方原始报价作为具有自然属性的决策变量,进行成本-效益分析,计算综合竞争力指数和排名。本研究将模型应用于一公共基础设施承包商选择决策分析,结果显示,其分析结果与案例实际评标结果相比,表现出兼容性和优越性。

This paper proposed an outranking model with bi-directional cross evaluation for contractor selection. The model utilized both the passive rated-value and the active rating-value of each bidder which generated from the cross-evaluation matrix, adopted the entropy-TOPSIS method to compute the performance index which avails themselves of cost-benefit analysis by using the natural attribute of bid price. This method yielded an integrated competitiveness index for each bidders, and therefore assists contractor selection practice. We applied this model in a public infrastructure construction project bidding process, the results of the testaments showed that the method generated compatible and improved results compared with the method of current practice.
