Abstract
Due to the rapid development of green construction projects,scientific and reasonable selection of successful bidder which with excellent green construction ability is essential to the implementation of green construction projects. Combined with the characteristics and requirements of green construction project,this paper established a multi-level green construction project bidding evaluation index system based on the traditional construction project bidding evaluation index system. Using C-OWA operator to achieve the evaluation index weight,through the calculation of the green degree of construction project to conduct the preliminary screening,and the final use of vector angle cosine method for bidding scheme of optimization and index sensitivity analysis. The bid evaluation model weakens the adverse effects of expert's subjective preference of the index weight,and green construction index and green degree grade membership table are introducted. Adding initial screening in evaluation procedures makes selection results more objective and reasonable,and the combination of vector angle cosine and sensitive analysis makes bidding units specify weaknesses. Finally,an example verified the feasibility and practicability of the bidding evaluation model.关键词
