A Grey-Based Carbon Management Model For Green Supplier Selection

Green supply chain management has received much attention from scholars and practitioners over the past decade due to the increased emphasis on environmental issues from governments, customers, employees, competitors, and communities. Although a number of studies have addressed supplier selection problems from an environmental perspective, consideration of carbon management for supplier evaluation has rarely been discussed in the literature. Therefore, this study intends to develop a grey-based carbon management model for supplier selection in a green supply chain. Since decision-making in supplier selection generally deals with uncertain and incomplete information, we made use of an improved grey relational analysis in order to evaluate and select the most appropriate supplier. A numerical example is presented to show the efficacy of the proposed approach in supplier evaluations. The proposed approach in this study is novel and can be applied to other decision-making problems. Recommendations for future studies are presented in the final section.
