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.
