Possibilistic conflict analysis for group decision

A conflict is a situation in which two or more decision-makers are in dispute over some issue. Conflicts are, no doubt, one of the most characteristic attributes of human nature Generally speaking the main method for conflict resolution is based on game theory, where a conflict resolution is a kind of equilibrium state, such as Nash equilibrium and its extensions. Another newly emerging and interesting method for conflict analysis is based on rough sets; therein, three kinds of binary relations between parties, called conflict, neutrality and alliance are investigated. The conflict researched by game theory-based and rough set-based methods is from the participants, each with his own interests, who try to maximize his own interest as much as possible. Another kind of conflict is considered in this paper that is from the inherent diversity of knowledge and cognition on a specified event among multiple decision-makers in a decision group. The aim of this paper is to investigate the conflict situation of experts´ knowledge and research how to resolve such conflict to obtain more reliable and refined knowledge that can be used for decision-making
