Credibilistic Coalitional Game with Fuzzy Information

【摘要】：正As an important branch of game theory,coalitional game deals with situations that involve cooperation among the players.This paper goes into this topic further by incorporat- hag the fuzzy payoff information.Based on the credibility theory,we introduce two decision criteria to define the pref- erences of players,which leads to two new definitions of core —the solution of coalitional game.Meanwhile we develop one sufficient and necessary condition that provides a way to find the core.Finally,we give an example for illustrating the usefulness of the theory developed in this paper.
