On some classes of fuzzy information relations

摘要

Recently, E. Orlowska (1999) has proposed a many-valuedgeneralization of modal information logics which are logical systems forreasoning from incomplete and many-valued information. Following herideas, we consider a fuzzy generalization of some information relations.We provide basic properties of these relations and theircharacterizations formalized by means of fuzzy relational operators. Forparticular classes of fuzzy information relations the correspondingclasses of fuzzy information logics are defined and briefly discussed
