Relational Systems of Preference with One or More Pseudo-Criteria: Some New Concepts and Results

摘要: This paper proposes new concepts and results which could lead to a more realistic preference modeling than in classical decision theory. Sections 1–3 present four fundamental situations of preferences, their combinations the concept relational system preferences. In §4, particular case is studied. It associated with pseudo-criterion derived from criterion by adjunction two thresholds. Some are given, generalizing properties such well-known structures as complete preorders semiorders. 5 6 emphasize possibilities given preceding take imprecisions, irresolutions incomparabilities appearing every concrete problem where several criteria must be considered into account.
