PERFORMANCE EVALUATION IN AIRLINE INDUSTRY WITH CRITIC AND MEREC BASED MAUT AND PSI METHODS
Abstract
Due to the developments in the airline industry, competition among airline companies is surging day by day. It is very essential for airline companies to review their performance in order to sustain their activities. In this study, the five-year performance of Pegasus between 2016 and 2020 was analyzed. Accordingly, the criteria of "number of seats", "number of aircraft", "load factor", "average daily use of aircraft", "number of passengers carried" and "number of landings" were chosen. In the study, Pegasus' performance over the years was evaluated using the most up-to-date multi-criteria decision-making methods such as CRITIC, MEREC, MAUT and PSI. With the CRITIC and MEREC methods, the weights of the evaluation criteria were obtained, and the performance of Pegasus by years was listed with the MAUT and PSI methods. The results showed that the criterion with the highest weight on Pegasus' performance was the "number of aircraft", and the criterion with the lowest degree of importance was the "number of seats" criterion. In the ranking made by MAUT and PSI methods, Pegasus' best performance was in 2019, while the lowest performance was in 2020.
