Review article

The paper considers the criterion of quality of experts` selection based on the results of their work in the method of analysis of hierarchies, which is at present the most popular method of multi-criteria effecting the evaluation of factors affecting the formation and operation of complex systems. The analysis of the content of this criterion shows that it is too rigid and not fully substantiated. The insufficiently reasoned exclusion from consideration of a part of expert estimations can result in distortion of calculations in the methods and models where weight coefficients are used. The authors have come to the conclusion that the specified criterion can`t be used for single-valued assessment of the quality of expert judgments.
