Regional energy plans play a significant role in promoting the sustainable development of different regions in China. Most regions of China have formulated their energy plans. Selecting a reasonable sustainable energy plan is complex and involves a number of interactive criteria (e.g. technology, environment, economy and society). The traditional decision analysis methods, such as analytical hierarchy process and cost-benefit analysis, are not sufficient to integrate all the criteria with mutual interaction. On the contrary, the fuzzy integral methods provide a tool to resolve this problem and offer valid decision support since it is more appropriate to assemble and handle decision problems with interaction. This paper presents A fuzzy measure and fuzzy integral method for selecting the sustainable energy plan of Nanjing city in China. A set of energy planning alternatives are determined upon the implementation of installations of sustainable energy sources in Nanjing and assessed against economic, technological, social and environmental criteria.
