基于熵权——TOPSIS方法的施工评标模型应用研究

Entropy Weight and TOPSIS Based Bid Evaluation Model of Construction Applied Research

工程项目评标实质上是在多目标、多准则下对多个待选方案的评价决策问题,是业主选择合适的承包单位并确保工作顺利完成的关键。针对现有工程项目评标方法存在恶意竞争、评标因素及权重难以合理界定等缺陷,提出运用熵权原理和理想解法相结合进行施工评标的思想。首先分析现阶段存在的评标方法及其不足,根据评标的特点及影响因素建立评标的因素集体系,依据熵权法原理客观确定评标因素指标的权重,避免了多因素权重确定的主观性,又根据理想解法对评价对象进行排序,确定最优方案,最后通过建设项目的施工评标的实例来说明该方法的应用。

Engineering project evaluation is essentially in multiple targets, much more than choosing rules for evaluating the decision making problems. It is the owners＇ choices to determine some appropriate contractors and ensure that the key to finish the work. According to the existing engineering project evaluation methods brings malicious competition, evaluation factors and weights are difficult to be reasonable definition and defect, the article puts forward in using entropy principle and the ideal solution by combining the thought construction bid assessment. This article analyzes the existing evaluation methods and its shortcomings, and then based on the evaluation of the characteristics and the influence factors of the system to build bidding factor set. And then based on entropy weight method, it is to determine the objective principle of the index of evaluation factors, to avoid the many factors determining weight of subjectivity, and according to the ideal solution to evaluation objects for sorting, determined the optimal scheme, finally, through the construction of the construction of the project bid assessment that the examples of the application of this method.
