Working with the right supplier helps improve the quality of the enterprise’s products and services and keeps costs at the most appropriate level. Since there are multiple criteria in supplier selection, choosing the right supplier can be a complex problem. The preference criteria and the number of alternative suppliers can be challenging for decision-makers, and the rational decision-making process can be extended. This study aims to select the most suitable supplier for the raw leather material supply of a company manufacturing office chairs in the Organized Industrial Zone in Türkiye. AHP, TOPSIS, and WASPAS methods, which are different multi-criteria decision-making techniques, were used to solve this problem, and the results were compared. The managers’ opinions of the company’s production, purchasing, and quality control units were consulted to determine the criteria required for the use of the methods and to evaluate these criteria. As a result of the literature and expert opinions, four main criteria and eight sub-criteria were formed. The main criterion was cost, followed by quality, delivery, and support. Suppliers were evaluated using all three techniques and ranked for the company.}, number={2}, publisher={Düzce Üniversitesi}
