[en] Good or bad choices based on crisp outranking relation correspond to dominant and absorbent kernels in corresponding digraph. In this paper we generalize both concepts to an ordinal valued outranking relation. An efficient algorithm for computing these choices is proposed. Furthermore, we show the formal correspondance between ordinal valued choices and kernels in ordinal valued digraphs.
