A fuzzy multi-objective optimization model for energy structure and its application to the energy structure adjustment — in World Natural and Cultural Heritage Area∗

Tourism brings about great economic benefits. However, it inevitably causes severe environmental issues at the same time as it consumes energy and produces emissions, which would impact the tourism areas in many respects negatively. As for a region entitled as the world heritages of the nature and culture, the issue of energy reduction and dependency of the economies on energy has made the need for energy diversification more urgent. This paper focuses on the low-carbonized adjustment of energy structure in world natural and cultural heritage area. By applying linear multi-objective optimization method, we construct a fuzzy multi-objective optimization model analyzing the relationship between energy and social economic, and environment. Besides, we take Shizhong District of Leshan city (LSD) in China as our study case and present solutions on the low-carbonized adjustment of energy in this area from a quantitative perspective.
