摘要
Data mining in incomplete information systems is a hard problem but inevitable in uncertain decision. In thispaper ,an extended rough set model based on dominance relation is combined with fuzzy set theory for data mining ininterval valued decision table ,then decision rules can be obtained from the decision table. Simulation results show thatthe method is effective.
