Özet:

Multi-Criteria Decision Making (MCDM) is defined as the process of determining the most suitable alternative among the alternatives by evaluating the criteria that may conflict with each other. This study uses Gray Relationship Analysis (GRA), MOORA and PROMETHEE methods to rank the quality of life in the Turkey’s provinces. The study aims to compare the findings obtained from different methods. The study evaluated the quality of life between Turkish provinces under 41 criteria by utilising data from Turkish Statistical Institute. In line with the results, the top five provinces ranked by at least two methods were found as Istanbul, Yalova, Ankara, Antalya, Karabük and Zonguldak. In contrast, the last five provinces that were ranked by at least two methods were found to be Ağrı, Iğdır, Muş, Şanlıurfa and Hakkâri. The applications made in the study revealed that different MCDM methods can yield significantly different results. It is predicted that it would be more meaningful to classify the provinces rather than rank them in determining the quality of life.
