摘　　要：冲突分析有利于信息系统的问题处理。为了促进相关动态学习,将冲突分析模型推广到动态形式信息系统中,并结合三支决策思想研究基于属性值变化的动态三支冲突分析。首先,考虑单行属性值变化,研究距离矩阵的变化,得到关于冲突集、中立集、联合集的三支分析模型的变化结果。其次,类似考虑多行属性值变化,得到对应的三支分析模型的变化规律,并由此设计相关的动态更新算法。进而,针对列属性值变化,基于形式信息系统来转换成行属性值变化,从而调用行值动态更新方法。最后,实例分析说明了所得动态三支冲突分析的性质与算法的有效性。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.
