This paper deals with the selection of technological vehicles to the specific mining and geological conditions in open cast surface mining. The problem is formulated as a multiple criteria ranking of variants, which are different types of technological vehicles. They are evaluated by the family of ten criteria according to several aspects, including: economy, technology and construction, exploitation and reliability. Vehicle selection is carried out by the group of decision makers involved in the decision process. They are professionals with different expertise profiles. The solution of the problem is performed with an application of stochastic group decision aiding method proposed by the authors. This approach is composed of five phases, i.e.: 1) analysis of the decision situation, 2) construction of variants, and definition of the set of criteria, 3) evaluation of variants, 4) preference modeling and computations, 5) construction of the stochastic ranking. The obtained results are compared with the previous research on selection of technological vehicles based on separate individual preferences of each expert.
