研究社会行为主体间信息交互模型优化问题,社会在应用多主体建模技术模拟人群社会行为的过程中,多主体间的信息交互模式决定着主体自组织和自学习的方式和效率.从现实社会中人与人之间的消息传播行为规律出发,分析主体间信息交互过程,以信息生命周期理论为基础建立多主体间信息交互模型,给出主体信息交互各个阶段的形式化方法和表述结果.利用新闻传播学中消息的5W1H定义来表达信息内容,采用时态逻辑描述单一主体信息需求的判定,应用多目π-演算形式化方法表述多主体获取和转发信息的行为,使用模糊集和Brooks方程分别表示信息过滤与信息吸收行为.进行分析的结果表明,多主体间信息交互模型的建立及其形式化描述,可为人群社会行为仿真模型的实现奠定了基础.%In the process of simulating social behavior of population with multi-agent modeling technology, the information exchange mode between the multi-agent determines the main method and efficiency of its self-organization and self-learning. On the basis of the behavior law of message spread between people in real society, the process of information exchange between multi—agent was analyzed and the information exchange model based on the information life—cycle theory was built, and the main of the formal methods and express results of information exchange between agents at all stages was given in this paper. The theory of "5W1H" in Journalism was imported to define the structure of the message content. The temporal logic theory was used to describe the information exchange requirement, The π —calculus theory was used to describe multi-agents' behavior of information receiving and sending. The fuzzy set theory was applied to express the information filtering, and the Brooks equation was used to explain information absorption. The formalized description and design of the model pave the way to implement the model.
