What should we expect from a multicriteria aggregation procedure for non-cardinal or mixed evaluations?
Very often, in multicriterion analysis, the actions to be compared are evaluated according to a set of conflictual and heterogeneous criteria. Also these evaluations can contain elements difficult to quantify. In this case, dominating informations are often noncardinal or mixed. Several procedures of multicriterion aggregation (MCAP) are implemented in such a context. After reminding the main difficulties which a MCAP can encounter in such a context and this from the theory of measuring viewpoint, we propose a set of requirements which should be checked by a MCAP so it can be described as acceptable for such evaluations.
