基于组合赋权TOPSIS模型的项目评标方法研究

项目评标对业主选择最为适宜的承包商从而确保工程顺利完成至关重要,其本质是多目标情景下对多方案进行全面、客观的评定与优选。为改善现行评标模型的可靠性与便利性,将TOPSIS模型引入到项目评标决策中;通过深入分析评标指标赋权的特殊意义,提出了Delphi-AHP法和熵权法相集成的主客观组合赋权法,使权重既反映决策者主观偏好,又凸显方案客观差异;进而,构建了基于组合赋权TOPSIS模型的项目评标方法。通过案例研究,表明该方法的可行与高效,其得到的评标结果具有更好的区分度与决策精度,可以为业主决策提供更为科学、客观的依据。

Study on Project Bidding Evaluation Method Based on Combination Weighting TOPSIS

Project bidding evaluation is of vital importance for owners to select the most suitable contractors to complete the project successfully.In order to improve the reliability and convenience of existing methods,TOPSIS model is introduced into project bidding evaluation.Through analyzing the special meanings of weighting for bidding evaluation indexes,this paper proposes a combination weighting method integrating Delphi-AHP and entropy method,which not only reflects decision-makers＇ subjective preference but also highlights the objective differences of schemes.Then,the project bidding evaluation method based on combination weighting TOPSIS is established.Finally,a case study is given,which shows the method introduced in this paper is feasible and efficient,and has better differentiation degree and decision accuracy.
