An Integrated Neutrosophic SWARA and VIKOR Method for Ranking Risks of Green Supply Chain

Abstract

The green supply chain (GSC) plays a vital role for companies and organizations. Though there are several risks thread GSC Hence, these risks need to be ranked for companies. So, the goal of this study ranking these risks under a neutrosophic environment due to this problem contains uncertain information. So, this study proposed a multi-criteria decision making (MCDM) for dealing with conflicting criteria and used MCDM methods. This study introduces an integrated model with Stepwise Weight Assessment Ratio Analysis (SWARA) and visekriterijumsko kompromisno rangiranje (VIKOR). The SWARA method is used to calculate the weights of criteria and the VIKOR method is used to rank the risks of GSC based on six main criteria and twenty sub-criteria with ten risks (alternatives). Then the proposed model was evaluated by a numerical example. Finally, the sensitivity analysis is conducted.
