Abstract:Through the study of China’s offshore wind power projects,a social evaluation index system of offshore wind power projects based on its characteristics is established,and it is used to study actual cases. In order to determine the social evaluation index weight of offshore wind projects,the theory of rough sets and information gain is used to improve instability and subjectivity of AHP algorithm. Considering the subjective and objective weight,a reasonable and effective combination weight is obtained. Finally,fuzzy comprehensive assessments with and without a project are carried out. The introducing of rough sets and information gain makes the evaluation results more objective and scientific,which providing a valid basis for investment decision-makers.
