TY - JOUR TI - An application of the intuitionistic fuzzy PROMETHEE method in the selection of transportation service AU - Citil Mehmet JN - Thermal Science PY - 2022 VL - 26 IS - 102 SP - 613 EP - 620 PT - Article AB - Many of the problems we encounter involve uncertainties. Intuitionistic fuzzy logic works well in solving problems with uncertainties. Transportation problems, which are needed find the most appropriate and best, also contain uncertainty. A solution is found by using one of the decision making methods by determining the weight values of the criteria. The PROMETHEE method has an important place among the multi-criteria decision-making methods as it allows the decision maker to observe both positive and negative rankings. We may solve problems with uncertainties through using intuitionistic fuzzy logic. In this study, a new and different solution method is presented to find the most suitable transportation service provider by using the intuitionistic fuzzy PROMETHEE method. Criterion weight values were determined by controlled sets. Decision makers may apply this method to their problems by changing the weights we use depending on the importance of their criteria.
