分析了基于经济理论的理性人假设的含义,从心理学观点对人的动机进行分类,指出理性人假设是针对普通动机激发的人而不是超越性动机引发的人,他们谋求利益的最大化和损害最小化.为了对利和害进行量度和规范的描述,文中结合数学与物理中场论和人工智能中状态空间的概念,提出利益场的概念和相应的理性人定义,指出在利益场中博弈者为取胜所要考虑的局势变化及评价函数等六个重要因素,通过二手车交易这个典型实例说明利益场中各因素的描述方法和计算方法.

Abstract:

An analysis is made of the meaning of rational person hypothesis based on economic theory.The human motivation has been classified from the viewpoint of psychology.It is pointed out that the rational person hypothesis applies to the people inspired by ordinary motivation rather than exceeding motivation.They aim at maximizing their benefits and minimizing their damages.To measure the benefit and damage,and give a regular description,the concept of benefit field and a new definition of rational person have been proposed based on field theory of mathematics and physics with the concept of space state in AI.It emphasizes that the game players in the benefit field should consider six important factors including situation changes,evaluation function and so on.The paper presents a typical case study of the second hand cars trade to illustrate the method of description and computation of six factors in the benefit field.
