Abstract:
The Pawlaks conflict analysis model is generalized to the incomplete information systems, three-way conflict analysis based on incomplete information systems is studied with the thought of three-way decision. Firstly, the missing value are processed and the incomplete information systems are transformed into the complete information systems. Secondly, the conflict relationship of agents is discussed, and the conflict analysis model in incomplete information systems is established by the concept of conflict similarity distance. Finally, the threshold of the tri-partition of the agents is computed by the decision-theoretic rough sets, so as to get the most reasonable tri-partition decision result.
