摘要
分析了主体知识在应对不确定环境方面的作用,指出主体知识对其决策的作用不仅局限于传统分析所述的辅助,还具有替代理性计算决策的功能。依赖主体知识进行的规则支配决策与依赖消耗资源进行理性计算决策,是主体权衡偏差成本与决策成本的理性结果。在节约偏差成本的目标指引下,主体知识的最优特征受到环境事件概率分布的影响。存在一个环境事件概率分布的临界值,可用以分割主体决策的两种模式,确定依赖主体知识进行规则支配决策的适用领域。
The issue analyses the role of knowledge in dealing with environmental uncertainty, we pointed out that the role of knowledge in the process of agents' decision making is not only assistant which has been discussed a lot in literatures, but also has a substitute influence to the rational calculate. Whether to choose the rule - oriented decision mode which has cost named deviation cost or to choose the rational calculate decision mode which cost resources, is the rational decision of agents by weighing between deviation cost and decision cost. Directing by saving deviation cost agents will arrange their knowledge according to environmental circumstance. There exists a critical probability of environmental circumstance which determines the domains of using which type of decision mode.
