The study was carried out with Analytical Hierarchy Process-AHP, Fuzzy Analytical Hierarchy Process-FAHP, Technique for Order Preference by Similarity to Ideal Solution -TOPSIS and Fuzzy Technique for Order Preference by Similarity to Ideal Solution- FTOPSIS, which are multi-criteria decision making methods, and total scores were calculated for 10 projects taken from different departments in the project evaluation forms prepared. The ranking was made by comparing the projects within themselves according to the scores formed. 4 different methods were compared and combined with the Copeland Method, which is a common ranking methodology, and the final ranking was revealed. Afterwards, the correlation of each method with the integrated ranking was examined.
