摘要: 信任是多主体系统(MAS)研究的一个热点问题。为了解决MAS的动态性和不确定性带来的信任问题,提出了一种基于概率论的信任模型。与现有的信任模型相比,该模型考虑了信任信息的完整性和信任的动态性:即在估价agent的信任关系时引入了信任的精确度信心和时间退化因子。模拟实验表明,时间退化因子和信心的引入,能更加有效地评估agent之间的信任关系。

Abstract: Trust is a hot topic in multi-agent systems.The mathematical models of trust play an important role in determining who and how to interact in open and dynamic environments.To this end,a mathematical trust model based on probabilistic theory is proposed in which agents can autonomously deal with the biased information and identify trust belief with aging factor in multi-agent systems.
