有限理性条件下博弈方决策规则获取的粗糙集方法

A Rough Set Method for Extracting Players' Decision-making Rule Based on Bounded Rationality

经典博弈理论是基于完全理性假设成立的,有限理性理论的诞生对经典博弈理论是一个极大的冲击．该理论认为博弈方的决策能力是有限的,博弈方的决策受到各种因素的影响,因而在众多因素中获取决策规则的问题变得相当重要．论文算例给出了影响博弈方决策的因素,应用粗糙集方法,提取博弈对手的决策规则,使博弈方深入了解对手情况后,作出新的决策．

The classical game theory is based on absolute rationality, but absolute rationality nardly exists in real life. The appearance of bounded rationality theory is a big impact on the classical game theory. The bounded rationality theory says players＇ decision-making ability is limited; their decision-making is affected by various factors. So the problem of extracting the decision-making rule from many factors is becoming quite important. A rough set method is applied to extracting opponents＇ decision-making rule from influencing factors. By this method, players can make new decisions after knowing their opponents thoroughly.
