Abstract To study knowledge representation and knowledge acquisition in inconsistent decision systems with multi-granular labels, the concept of multi-granular labeled information systems is firstly introduced. Indiscernibility relations on the universe of discourse in a multi-granular labeled information system are defined. Representations of equivalence classes with different levels of granulation as well as their relationships are also explored. Lower and upper approximations of sets with different levels of granulation are further defined and their properties are presented. Finally, concepts of eight types of consistence and optimal granularity with various meanings in inconsistent multi-granular labeled decision systems are proposed and their relationships are examined.

Key words： Belief Function Granular Computing Information System Multi-granular Labeled Decision System Rough Set
