SELECCIÓN DEL REFRIGERANTE ALTERNATIVO APLICANDO LAS TÉCNICA AHP Y ANP

Abstract

In this paper, a method to select the best alternative refrigerating that complies with Montreal and Kyoto protocols using multi-criteria decision analysis, specifically AHP and ANP is proposed. Four refrigerating groups were selected, one synthetic (HFC) and three naturals like ammoniac, carbon dioxide and hydrocarbons. The four groups were evaluated by three experts under criteria such as performance, flammability, toxicity, global warming, ozone layer impact and economy. EC2000 and SuperDecisions software were used. According to AHP results, ammoniac is the best alternative refrigerant, while ANP results show hydrocarbons to be the best ones. Through this methodology the application of MCDM to solutions techno-economics was validated. Keywords: alternative refrigerants, AHP, ANP
