Annotation: The article suggests methods for determining the collective ranking based on the indirect approach. We consider the case of fuzzy expert preferences given in the form of matrices of fuzzy tournaments and also the case of ordinal fuzzy expert assessments. For aggregation used method for calculating the linguistically quantized speech as well as OWA operator. The first method makes it possible to do without the complex optimization problems that arise in group decision making. Another method can be used for direct ranking of alternatives by experts.

Keywords: fuzzy expert judgements, group decision making, group ranking, indirect approach.
