An Integrated Fuzzy Multi-Criteria Approach For Evaluating Sustainable Suppliers In Supply Chains: AHP, TOPSIS, And VIKOR

Abstract

In today’s rapidly changing regulatory landscape, with stricter environmental laws and increasing corporate pressures to adopt sustainable practices, companies must bolster their capabilities in implementing GSCM activities. This pressing need drives organizations to seek robust tools for evaluating and selecting eco-friendly suppliers.  One promising approach is the use of Multi-Criteria Decision-Making (MCDM) methods, which enable comprehensive assessment and ranking of potential providers based on multiple relevant factors. To this end, the study introduces two advanced fuzzy-based decision-making techniques—fuzzy TOPSIS, fuzzy AHP and fuzzy VIKOR—designed to enhance supplier selection processes within green supply chain networks. These innovative methods provide a nuanced and flexible framework that captures uncertainties and subjectivities inherent in real-world decision environments, ultimately helping organizations make more informed, sustainable choices.
