Green supplier's selection using economic and environmental criteria in medical industry

The Green Supplier's Selection (GSS) approach was used in this paper. This approach is focused on environmental and economic criteria when selecting suppliers. This enables the growing demands of different stakeholders to be met. The GSS approach was conducted on the example of the Ghetaldus Brcko Polyclinic with the application of expert decision-making. During the GSS, it is crucial for Ghetaldus Brcko Polyclinic to obtain materials and services that are not harmful to the environment, thus reducing the environmental pollution. The experts assessed the importance of the criteria used and the importance of the observed suppliers. The fuzzy PIPRECIA (Pivot Pairwise Relative Criteria Importance Assessment) method was used to determine the importance of the criteria, while the fuzzy ARAS (Additive Ratio Assessment) method was used to rank suppliers. The results have shown that the most important sub-criteria for experts is the green product and quality when choosing a supplier, and supplier A4 best meets the goals set by the Ghetaldus Brcko Polyclinic. These results were confirmed through the evaluation of the results and by the application of sensitivity analysis. The contribution and importance of this study to provide the methodology that will enable the selection of green suppliers who will provide equipment and materials that are not environmentally harmful and thus the environment is protected because the green supplier cares about environmental protection. The research approach has shown great flexibility because it is adapted to human thinking; thus, it should be used in future studies.
