Vague-Set Fuzzy Approach for Comprehensive Benefit Evaluation of Low-Impact Development in Urban Residential Areas

  • Hui Qiu, Shouyun Shen, Xin Yi

Abstract

Low-impact development (LID) is encouraged in many communities as a sustainable engineering technologyto reduce the adverse effects of urbanization. In recent years, many LID residential areas have been built in China, while studies of the performance of LID after construction are lacking and it is difficult to obtain ideal results of comprehensive benefit of LID in urban residential areas by traditional methods. The aim of this research is to establish a comprehensive benefit evaluation system for LID. Since some evaluation indicators of LID are fuzzy and make an accurate judgment difficult, a vague-set fuzzy approach was proposed and a case study was presented to illustrate how the model is applied. Our results show the effectiveness of LID project in protecting the water environment and improving the quality of people’s lives in residential areas. Similarly, the evaluation of second-level and third-level indicators is described and illustrated in the case study. The Vague-set fuzzy approach will help designers, engineers, and municipal officials to recognize the advantages and shortcomings of LID technology in residential areas in China.
