Abstract: In this paper, we consider the problem of bus selection for public transportation using a hybrid multicriteria decision making approach. The problem includes several conflicting factors which are economic, social, and technological factors. The integrated approach brings the flexibility of fuzzy AHP and simplicity of fuzzy VIKOR methodology together. To demonstrate the applicability of the methodology, a case study for Ankara, the capital city of Turkey, is given. A four levels hierarchy is established, and three experts are utilized for assessing the pairwise comparison matrices. The weights of the criteria are determined by fuzzy AHP and then the alternatives are ranked by fuzzy VIKOR. A sensitivity analysis is also made to see how sensitive our decision to the changes in parameters of methodology is. Buckley's fuzzy approach is finally implemented to problem and the obtained results are compared.
