GRA-Fuzzy-Based Green Urban Planning Scheme Decision-Making

In order to improve the sustainability of urban construction and development, governments at all levels in China have launched a large number of policies related to urban green planning one after another. However, the program design of urban green planning itself is a complex system engineering, and the scientificity of program decision is important for the smooth implementation and sustainability effect of urban planning programs. To this end, this paper proposes a GRA-Fuzzy-based urban green planning scheme evaluation model. The method starts from the program itself, analyzes the operation and guarantee measures of the program, and combines with the analysis of relevant literature to establish the evaluation index system of urban green planning program; on the basis of fully considering the uncertainty, coherence, fuzziness, and grayness of the evaluation index of urban green planning program, it combines the non-addressable Shapley value assignment method, fuzzy and gray system theory to form a comprehensive evaluation model of urban green planning. Finally, the empirical study shows that the model can effectively evaluate the urban green planning scheme.
