Sumario:A methodological combination of the DRV Processes and the ELECTRE I method is proposed to obtain a kernel solution and consensus-building. DRV processes include three phases: stabilization, aggregation, and ordering. The first phase concerns problem structuring, preferences evaluating so that the forms of ignorance of information are controlled and the consensus is favored. Aggregation phase was originally carried out with linear weighting, a strategy that allows us to obtain an ordering or the selection of the best alternative. Solutions to problems that seek to discriminate a kernel set are not formalized. A methodological combination is formalised to find kernel solutions in group decision making and we show an application case in which we obtained the set of good alternatives. The results show that the bias of underestimating good points with low importance is reduced using outranking methods in the aggregation and ordering phases.
