摘　　要：文章从评标改进着手,针对国内现有评标方法单一的现象,提出综合评价的观点。对国内现有评标方式进行类比分析,提出两种方式相结合的评标模式。并根据决策单元多输入多输出的特点建立了评价指标体系。引用信息熵对建筑施工企业投标能力进行综合评价,严格界定各个指标的权重,使其更加符合优中选优的原则,且进一步降低了评标中的人为因素,减少了随意性,有利于消除建设项目评标过程中的不良弊端。在对决策单元做出客观、科学评价的基础上提高了评标效率,并结合实际案例进行验证。This paper starts with the improvement of bidding evaluation,and puts forward the viewpoint of comprehensive evaluation directing at the single domestic evaluation approach.It made analog and analysis on the existing domestic evaluation approach and brought forward an evaluation mode combining two ways.Then it built the evaluation index system according to the multiple-input and multiple-output,characteristics of the decision-making unit.The article introduced information entropy to the comprehensive evaluation of the bidding ability of the construction companies,strictly defined the various weights of each index to make them the priority among priorities,and further reduced the human factors in the evaluation and decreased the randomness to eliminate the defects in the process of evaluation in construction projects.This paper enhanced the efficiency of bidding evaluation based on the objective and scientific evaluation on the decision-making unit,and verified its effects.
