[1, 2] is based on paired comparison methods which are easy to understand and uses qualitative data only in a mathematically justifiable way. The computational steps of the method are simple and can be easily apply to various complex problems. Classical REGIME techniques uses crisp numbers to evaluate qualitative evaluations. In this paper we propose Spherical Fuzzy REGIME techniques which employs Spherical Fuzzy Sets proposed by Gündoğdu and Kahraman [3] to represent evaluations. Spherical Fuzzy Sets (SFS) are a new extension of Intuitionistic, Pythagorean and Neutrosophic Fuzzy sets. The proposed Spherical fuzzy REGIME (SF-REGIME) method is applied to the evaluation of waste disposal site selection problem. The decision model is constructed for three alternatives and five criteria in order to demonstrate the performance of the proposed SF-REGIMR method.
