The present study is aimed at increasing the accuracy of multi-criteria evaluation of alternatives in selecting a location for establishing an intermodal terminal in the North-Central planning development region of Bulgaria. A model has been used in the paper that allows us to increase the accuracy of multicriteria evaluation of all studied alternatives. This has been achieved by converting the values of various units into identical dimensionless units within a defined interval. It makes it possible to do an evaluation of the alternatives by using the real values of the criteria. The model has been used for multi-criteria evaluation of the alternatives in selecting a location for establishing an intermodal terminal in the city of Ruse. The results have been compared with the results of a pre-feasibility study of establishing an intermodal terminal in the city of Ruse in the North-Central planning development region of Bulgaria.
