Abstract:
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.
