Abstract: In order to promote construction of offshore wind farms in far-reaching sea areas and rational use of ma-rine resources,a decision-making model based on fuzzy logic is proposed for site selection of offshore wind farms in far-reaching sea areas.First,influencing factors are identified from existing studies,based on which a three-layer decision-making framework is established.Second,input and output variables are fuzzified,and four fuzzy logic boxes are estab-lished by using decision attributes,which are wind resources,natural environment,traffic environment,and fan condi-tions.Then associated reasoning rules are also developed.Third,weights of decision attributes are derived by using lin-guistic variables for final decision-making.Finally,take site selection of offshore wind farms in Shanghai as a case study, its scheme is determined by this method.
