A Conflict Analysis Model Based on Three-Way Decisions

In decision-making, three-way decisions play an essential role and have been widely used in many fields and disciplines. In this paper, we propose a conflict analysis model based on three-way decisions, so as to explore the inter structure of conflict situation. Firstly, by adopting including degree, two pairs of evaluation functions are defined specifically based on the conflict situation. After that, with restricting the evaluations, three regions of agent set and issue set can be obtained. Comparing with existing conflict analysis models, this trisection model is more efficient, practical and pragmatical. Finally, the trisection of agent set and issue set could be used to ascertain sub-optimal feasible consensus strategies, and determine the scope of the kernel issues in conflict situation, respectively.
