Study on Scheme Optimization of Urban Water Diversion Project based on Fuzzy AHP-TOPSIS

In order to solve the problem that the evaluation index value is fuzzy and the index weight is incomplete in the evaluation of urban diversion project, a comprehensive evaluation method of urban water diversion project based on fuzzy AHP- TOPSIS is proposed. In order to fully combine the advantages of the two factors, the index factors are divided into ordered levels by fuzzy AHP, and the weights of each level are scientifically determined, and then the fuzzy AHP-TOPSIS comprehensive evaluation model is constructed in combination with TOPSIS. The optimal scheme is determined according to the degree of approximation between the finite qualitative and quantitative indexes and the ideal target. Through the analysis of examples, it is shown that the evaluation method is scientific in theory and practical in practice. It is operable in practice.
