本文研究了一类特殊的不完全信息博弈,其中局中人的收益是随机的和模糊的。这样的游戏被认为是在贝叶斯游戏的背景下,不确定的类型,其特征在于作为模糊变量。然后引入静态模糊贝叶斯博弈,并基于可信度理论给出了局中人的决策规则。我们进一步证明了博弈均衡的存在性。最后,作为一个应用,研究了信息不对称条件下具有模糊效率的古诺竞争模型,并给出了一些结果。
This paper studies a special game with incomplete information, in which the payoffs of the players are both random and fuzzy. Such a game is considered in the context of a Bayesian game with the uncertain types characterized as fuzzy variables. A static fuzzy Bayesian game is then introduced and the decision rules for players are given based on credibility theory. We further prove the existence of the equilibrium of the game. Finally, a Cournot competition model with fuzzy efficiency under asymmetric information is investigated as an application and some results are presented.
