Comprehensive bid evaluation method for construction projects based on fuzzy entropy weight

A fuzzy decision making model based on fuzzy entropy weight was presented for the bid evaluation in construction process. Considering the fuzziness in bid evaluation process and the expert knowledge of the construction project,utility value of data reflected by fuzzy information entropy was used to calculate the weight coefficient of evaluation index. The index weight identified by experts was modified by fuzzy entropy weight,and the comprehensive weight of the index system was defined, which resolve the weight allocation. The double base points method of multiple attribute decision making analysis was used to analyze the judgment results. The ranking of response level of tender to construction project was provided for the owner,which helps the owner to choose the successful bidder.
