Green Supplier Selection via an Integrated Multi-Attribute Decision Making Approach

The environmental awareness of society and the global competition market has increased significantly due to the environmental problems that happen today. Companies have recognized the importance of focusing on environmental issues in order to be strong in a modern competitive business environment. Therefore, environmental factors are taken into consideration during the supplier selection process, which is an important decision point in the supply chain. In this study, two robust multi-attribute decision making techniques, Intuitionistic Fuzzy AHP (IF-AHP) and PROMETHEE, are used in an integrated way to better handle this selection problem. The steps are clearly explained in the proposed methodology. First, the relative weights of the criteria are determined by IF-AHP, which allows decision makers (DMs) to deal with the uncertainty of the evaluation process. Subsequently, the weights of criteria obtained are used in the PROMETHEE method for the best ranking of alternative suppliers. An application is performed in the air filtration industry to demonstrate the validity of the proposed method.
