Health tourism is one of today's rapidly growing economic areas. Promotional activities must be carried out in order to increase the income to be obtained from health tourism. It is necessary to select the best center for these studies to be prepared effectively. Multicriteria decision-making approaches can be considered in use of the selection of the best health tourism center. This study proposes a fuzzy multi criteria decision making methodology in evaluation of four alternative health tourism centers in Turkey. A new circular intuitionistic fuzzy multi-criteria decision-making approach was developed by evaluating the alternatives with intuitionistic fuzzy numbers by experts. In addition to the existing literature, this study contributes to circular intuitionistic fuzzy sets by proposing new defuzzification functions. The study aims to guide future circular intuitionistic fuzzy multi-criteria decision making approaches.
