摘要
结合实际语义,研究基于区间值模糊冲突表的三支冲突分析。首先,定义区间值模糊冲突表,分别给出基于单议题和多议题上的冲突集、中立集和联盟集,并据此做出决策。其次,提出议题损失函数的乐观、悲观聚合方式,给出一种基于决策粗糙集理论计算阈值的方法。最后,通过例子分析了上述定义的两种损失函数聚合方式下得到的冲突分析结果。
Conflict exists in various aspects of human society,and most people's attitude towards conflict is not clear acceptance or rejection.In order to discuss conflict more intuitively,combined with practical semantic,the three-way conflict analysis based on interval-valued fuzzy conflict situation is studied.Firstly,the interval-valued fuzzy conflict situation is defined,and then conflict set,neutrality set and alliance set are given based on single issue and multiple issues respectively,which can help us make decisions.Secondly,the optimistic and pessimistic aggregation methods of loss function are proposed,and a threshold calculation method based on decision-theoretic rough set theory is introduced.Finally,an example is displayed to show the results of conflict analysis based on two aggregation functions defined in this paper.
