Performance evaluation of green supply chain management using the grey DEMATEL–ARAS model

Abstract

Under stakeholder pressure and more strict regulations, firms need to enhance green supply chain management (GSCM) practice using multidimensional approaches. In view of these facts, a multi-criteria decision-making (MCDM) technique can be implemented while evaluating GSCM performance of alternative suppliers based on a set of criteria to deal with vagueness of human perceptions. The grey set theory is used to interpret the linguistic preference in accordance with the subjective evaluation. The cause–effect relationships among GSCM criteria, as well as their weights are considered using the grey DEMATEL approach. The grey ARAS method is also applied, using the weights obtained, for evaluating and ranking the GSCM performance of alternative suppliers. A sensitivity analysis conducted to ensure the reliability of solutions is described and the comparison of the applied technique with other MCDM methods such as grey TOPSIS and grey COPRAS is provided.
