We consider aggregation of multiple criteria evaluations expressed on qualitative ordinal scales, which means representation of multiple criteria preferences using finite sets of values, such as "bad", "medium", "good", or "weak", "normal", "strong". The evaluation scales regarding single criteria, as well as comprehensive evaluations, are qualitative. Moreover, the qualitative evaluations concern either single alternatives (e.g., x is "bad", or "medium", or "good") or degrees of preference for pairs of alternatives (e.g., x is "indifferent" to y, or x is "weakly preferred" to y, or x is "strongly preferred" to y).
