Abstract

Aiming at the problem that the general rough sets can not present complete decision-making rules from limited data, the positive, negative and mixed consistent decision-making information system were defined. Method of obtaining rules for positive consistent system based on dominance relation was researched. Based on this, methods of obtaining rules for negative and mixed consistent systems based on dominance relation were put forward. A dominance rough sets method for consistent decision-making information system was then presented. The method was applied in the threat assessment of UCAV's targets. Decision-making information system for threat assessment of UCAV's targets was established. Preference of targets' attributes was analyzed. Decision-making algorithm was given, complexity of which was analyzed, and compared with dominance rough sets of Greco. Results show that the method is simple and rules can cover all values of the attributes.
