Knowledge Acquisition of Inconsistent Generalized Multi-scale Ordered Decision Information Systems
Aiming at the problem of optimal scale combination and IF-THEN knowledge acquisition in in-consistent generalized multi-scale ordered decision information systems,the concept of set-valued domi-nance matrix was firstly proposed,and the conditions for judging whether an ordered decision information system was consistent were given. Then,in the inconsistent generalized multi-scale ordered decision in-formation system,the concept of generalized decision based on dominance relation was introduced. At the same time,a new consistent generalized multi-scale ordered decision information system was constructed by defining the interval-valued dominance relation,and an algorithm for finding the optimal scale combi-nation through the set-valued dominance matrix was designed. The decision rules hidden in the inconsis-tent generalized multi-scale ordered decision information system were mined. Finally,the effectiveness of the proposed optimal scale combination of generalized decision was verified by experiments.
