Performance Evaluation of Sponge City Construction in a Residential Project

Residential project is an important component of sponge city construction management, and its performance has a significant impact on the disaster resilience and sustainable development of cities. This paper constructed a novel evaluation model based on the interval analytic hierarchy process and the improved TOPSIS. On the basis of consulting norms and literature research, performance evaluation indicators from the aspects of ecological benefits, economic benefits, and social effects were proposed. To accurately describe the preference and experience of decision makers, the interval analytic hierarchy process was used to calculate the index weight. An improved TOPSIS evaluation model was constructed by constructing a virtual negative ideal solution to avoid the same distance with positive and negative ideal solutions that might occur in the traditional TOPSIS. The Wuhan Yujingwan Project in China was selected for empirical research. The results showed that its sponge city performance was excellent, which was consistent with the actual situation. Compared with the analytic hierarchy process, the entropy weight method, and the traditional TOPSIS method, the advancement of the proposed method was proved.
