摘　　要：评标过程会涉及到大量的定性分析,定性分析过程中受到专家的经验知识和主观判断的影响较大,因而所确定的指标权重和指标值带有较强的主观模糊性,易造成评标决策的失误.基于模糊数能量化主观模糊性并融合到指标权重与指标值中,采用模糊理论对TOPSIS法进行改进,评价指标权重和指标值均用梯形模糊数表示,建立基于模糊TOPSIS法的评标模型.结果表明,依据CC值不仅可以对投标人排序,而且还能客观的反应出投标人自身的优劣,避免了劣中选优的情况发生.最后通过示例对提议模型的应用过程及可行性进行了说明.Evaluation process will involve a lot of qualitative analysis,qualitative analysis process by expert knowledge and experience and subjective judgment influence is bigger,and thus determine the index weight and index value with a strong subjective fuzzy,is easy to cause the failure of bidding decision.Based on fuzzy number to quantify subjective fuzziness and fused to the index weight and index value,this paper adopts the fuzzy theory to improve the TOPSIS method,evaluation index and weight of index values are trapezoidal fuzzy number is established based on the fuzzy TOPSIS evaluation model.The results show that,according to the CC value,not only can be sorted to the bidders,but also can reflect the bidders＇ own advantages and disadvantages.Finally,the application process and the feasibility of the proposed model are illustrated by examples.
