Research on energy conservation and emissions reduction based on AHP-fuzzy synthetic evaluation model: A case study of tobacco enterprises

How to evaluate the effect of tobacco industry's technical measures for energy conservation and emissions reduction is important to promote the application of advanced technology. Motived by this purpose, this study applies the fuzzy comprehensive evaluation method to construct a comprehensive index and use the Analytic Hierarchy Process (AHP) and Delphi expert consultation method to determine weights of indicators. Furthermore, the comprehensive evaluation of nine core energy-saving technical measures of tobacco industry is made. The results show that, the comprehensive performance of refrigeration system's optimized technique energy efficiency index is the best, which is 0.73, followed by air conditioning system and lighting system, which are 0.62 and 0.60, respectively. These results may provide insightful support for decision makers to promote the energy conservation and emissions reduction of tobacco industry.
