基于直觉模糊集的水利工程评标办法

Bidding evaluation model of water conservancy and hydropower project based on theory of intuitionistic fuzzy set

通过工程招投标形式选择合适的承包人是水利水电工程项目建设的关键,对工程建设计划的圆满实现起着决定性的作用。评标工作是整个招投标活动的核心,如何快速有效的选取最优投标人事关工程建设的成败,但是水利工程评标因素众多,且较难直接评价。对此,本文基于直觉模糊集理论,选取投标报价、施工组织及企业状况等指标,建立了指标属性矩阵和直觉模糊线性评价模型。该模型能够考虑评价对象各指标的隶属度、非隶属度和犹豫度,同时借助得分函数和TOPSIS法进行综合评价可快速求得投标单位投标优劣顺序,能够使评价结果更为合理。案例分析验证了该模型的有效性和实用性。

Through the project bidding to choose right contractor is the key of water conservancy and hydropower project construction,and it plays a decisive role in the fulfillment of the project construction.Bid evaluation is the core of the whole bidding activity,how to quickly and efficiently select the best bidder determines the success of the project construction.Project bid evaluation refers to many factors,and it is difficult to evaluate directly.In this paper,based on the theory of intuitionistic fuzzy sets,selecting bid quotation,construction organization and enterprise conditions as evaluation factors,the index matrix and intuitionistic fuzzy linear evaluation model were established.This model could consider membership degree,non-membership degree and hesitancy degree for all indicators.Subsequently,the priority order of the bid companies could be obtained by the using of scoring function and TOPSIS,which made the evaluation result more reasonable.And the validity and practicability of this model were verified by case analysis.
