In this paper we suggest an original approach to conducting individual pair comparisons during individual and group multi-criteria decision-making (including AHP/ANP-based decisions). With this approach every expert is given an opportunity to use the scale, in the degree of detail (number of points/grades) that most adequately reflects his/her competence in the issue under consideration for every single pair comparison. Before aggregation all separate expert estimates (judgments) are brought to a unified scale, and scales in which these judgments were built are assigned respective weights. A respective instrument for pair comparison conduction has been developed, and an experiment has been organized. The experiment statistically proves that as a result of suggested technology usage, there is an increase in the degree of correspondence between estimates, input by an expert, and his (her) own notions on examination objects.
