Dynamic three-way conflict analysis based on attribute value change
Conflict analysis facilitates problem processing of information system.To promote relevant dynamic learning,a model of conflict analysis is extended to the dynamic formal information system,and the dynamic three-way conflict analysis based on attribute value change is researched by combining the idea of three-way decision.At first,considering the change of single-row attribute value,the change of distance matrix is studied,and the change results of three-way analysis model on conflict,neutral and allied sets are obtained.Then,considering the change of multi-row attribute value,the change law of three-way analysis model is revealed,and the corresponding dynamic updating algorithm is designed.Furthermore,considering the change of column attribute value,the formal information system is utilized to implement a transform for the change of row attribute value,so the dynamic renewal method on row value is invoked.Finally,example analysis illustrates the effectiveness of the obtained property and algorithm of dynamic three-way conflict analysis.
