A fuzzy bag approach to choosing the ''best'' multiattributed potential actions in a multiple judgement and non cardinal data context

The present work is concerned with showing how a fuzzy bag construct along with the concept of a positive outstandingness predicate and that of a strict t-norm operator can be used to resolve conflicts and aggregation problems in decisions invoking multiple judgements and non-cardinal data. It is also shown how the differential expertness degrees of the judges may be taken into account in the aggregation process. The choice device proposed is decisive, i.e., it excludes incomparability.
