摘　　要：针对群组协同决策支持系统的特点,提出了基于决策者可信的信任模型.该模型通过决策者实体的历史行为证据来建立实体之间的信任关系,评估分布式环境下动态的决策者的可信度.给出了基于历史交互行为的直接信任度、间接信任度和通过信息熵理论来计算决策者的总体信任度的计算方法,为系统的安全决策提供了有效的解决方案.通过模拟实验验证了该信任模型的可靠性.This paper presents a trust model based on trusted decision makers with the characteristics of Group Collaborative Decision Supported Systems（GCDSS）.The trust model establishes the trust relationship among entities and evaluates the trust value of dynamic decision makers in distributed environment by historical actions of decision makers.The paper proposes a method of direct trust value computation,indirect trust value computation based on historical actions and integrated trust value computation by using entropy theory,which provides an effective resolvent for secure decision making.Lastly,the paper validates the reliability of the trust model by simulation experiment.
