Use of fuzzy TOPSIS, fuzzy EDAS and fuzzy VIKOR methods in selecting concrete suppliers in the construction industry

This thesis investigates the application of Fuzzy TOPSIS, Fuzzy EDAS and Fuzzy VIKOR methods for selecting concrete suppliers within the construction sector. Accurately selecting concrete suppliers in construction projects holds critical importance for project success and cost-effectiveness. In this study, the supplier selection process has been optimised by employing fuzzy logic-based TOPSIS, EDAS and VIKOR methods. Within the scope of the research, the selection criteria of various suppliers have been evaluated, and the most suitable supplier has been determined based on these criteria. The results demonstrate that the Fuzzy TOPSIS, Fuzzy EDAS and Fuzzy VIKOR methods offer an effective and reliable approach for supplier selection.
