The Study on Urban Sustainable Development Evaluation Using Engineering Fuzzy Set Theory

Urban sustainable development evaluation includes various indexes (economic index, social environment index). These indicators qualitative and quantitative research, so they are suitable for fuzzy comprehensive evaluation. This paper using comparative ordered binary fuzzy set theory (EFST) proposed by Professor Chen Shouyu determines the index weight, and then use the fuzzy pattern recognition model for urban sustainable development evaluation. At last, the paper explains the application method ‘example.
