Abstract:

Purchasing activities are of important for many businesses. Companies pay a fee to their suppliers at every stage for the products they supply, starting from the raw material to the final product, and this brings a financial burden. Today, with the awareness that competition and supplying the right product are very important, supplier selection has become an important issue. Supplier selection means not only choosing the best, but also supplying the right product at the right time and at desired quality. Within the scope of this study, it was focused on choosing the most suitable supplier for mechanical materials. The purchased materials were examined and criteria were determined to select the most suitable supplier. In order to supply these materials, a supplier selection application was implemented using Analytical Hierarchy Process. Five suppliers for the most purchased materials in the application were weighted according to the criteria and the most suitable supplier was determined. While weighting, questionnaires were applied to purchasing professionals who make operational transactions in their purchasing activities and after conducting surveys, comparison matrices were created. As a result of evaluating suppliers according to criteria, suppliers are ordered by applying AHP and details were presented. The study was concluded by discussing alternative methods that can be used in the evaluation of multiple questionnaires.
