Classifying environmental significance levels of production-oriented operational activities with F-ARAS and F-MOORA methods

Abstract

In most decision analysis approaches, application results are obtained in the form of a ranking or selection set. However, classification is needed for analysis of results. In this study, environmental significance levels and range values were created for the ranking results obtained using fuzzy Multi Criteria Decision Making approaches. Environmental significance levels have been established for 26 operational activities for which environmental impacts have been determined. Operational activities were analyzed using the Fuzzy-Additive Ratio Assessment (F-ARAS), Fuzzy-Multi Objective Optimization by Ratio Analysis (F-MOORA) Ratio, and F-MOORA Reference Point methods with six evaluation criteria, including the total impact score criteria. The results obtained were analyzed with environmental significance levels and range values, which can also be named as environmental risk classes created for the first time in this study depending on the changes in standard deviation. According to the comparison results, when F-ARAS and F-MOORA Ratio methods were evaluated together, 19 activities were in the same class (73%). Integr Environ Assess Manag 2022;00:1-12. (c) 2022 SETAC
