Different heterogonous criteria have to be considered for rail projects evaluation process. Due to this fact many authors suggest applying the multicriteria decision making methods. Often in practice there is certain uncertainty and imprecision during the rail projects evaluation process. Fuzzy numbers are suitable for taking into account these characteristics of a model. We develop the model for rail projects evaluation using the interval-valued fuzzy AHP and interval-valued fuzzy TOPSIS. Model is tested on the real rail projects at Serbian rail network. The proposed approach is suitable for making the transport projects evaluation model, with consideration of all conditions at real transport market.
