Given is a vector of experts' fuzzy evaluations of particular alternatives, and a vector of fuzzy weights of the experts (criteria). A choice problem is considered in terms of the ``mean'' aggregation procedure. Two approaches: ``pairing, then pooling'' and ``pooling, then pairing'' are considered. For both approaches, the determination of a (possibly small) subset of non-dominated alternatives is discussed. Finally, the ordering of alternatives is considered by using comparisons of fuzzy numbers.
