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.
