Performance evaluation of green suppliers using the integrated Fuzzy DEMATEL-AHP-VIKOR Multi criteria decision making techniques

Green Supply Chain Management (GSCM) strives to decrease, if not eliminate, supply chain operations' negative environmental effects. Multi-criteria decision-making (MCDM) strategies should be utilized to evaluate suppliers' GSCM performance because GSCM includes multi-dimensional methods. To address complex and confounding multi-attribute questions in a fuzzy environment, it is essential to devise fuzzy group decision making techniques. The present work introduces a methodology for evaluating the performance of firms in Green Supply Chain Management (GSCM) with regards to green design, green image, green transformation, green logistics, and green management system. This approach relies on integrated fuzzy MCDM techniques. The fuzzy DEMATEL approach is used to calculate the cause and effect corelation between GSCM dimensions. Based on this association, the fuzzy AHP technique is utilized to generate the weights of the relevant criterion. Finally, the fuzzy VIKOR technique is used to evaluate and rank the GSCM performance of alternative suppliers or organizations using the weights obtained from the fuzzy AHP method.
