Research on Energy Saving of Appliances with Evaluation Method and Application of Appliances Green Degree Based on Fuzzy-EAHP

Based on the characteristics of green appliances, the green degree evaluation index system is established from environment,resources,energy,economic,technology and society six areas. Fuzzy-EAHP applies the extension analytic hierarchy process (EAHP) to determine index weight of different levels. EAHP, which is more accurate and more objective than the traditional AHP, can quantitatively show the relative important degree between indexes with the extension interval number. Building the Mathematical model of three-lever fuzzy comprehensive evaluation, the first process comprehensive evaluation result is as input data of the latter process. At last, Fuzzy-EAHP is used to synthetically evaluate the green degree of four refrigerators. Key words: Extension analytic hierarchy process (EAHP); Green degree; Green appliance
