Attribute Reductions in Incomplete Intuitionistic Fuzzy Information Systems

Attribute reductions in complete intuitionistic fuzzy information systems based on dominance relations were introduced.However,attribute reductions in incomplete intuitionistic fuzzy information systems have not been investigated yet.In this paper,generalized dominance relations are firstly defined in incomplete intuitionistic fuzzy information systems and decision tables.The effective methods on attribute reductions are presented by introducing of discernibility matrix and discernibility function.
