摘　　要：提出一种基于模糊综合评判的主观信任模型,并给出该模型具体实现的方法,以对网络中主体的信任度进行评估。借助了层次分析法来动态的确定评判因素的权重,并引入"专家"对评判函数的权重,对第一次评判的结果作第二次综合评判。实例分析表明了方法的正确性,有一定创新和应用价值。This article presented a subject trust model based on fuzzy comprehensive evaluation, and gave the concrete method of realizing the model to evaluate the trust degree of a subject in the network. The article could confirm the weights of evaluation factors dynamically by means of Analytical Hierarchy Process（AHP）, and drew into the weights that expert had made for evaluation functions, to make a twice comprehensively evaluation for the first consequence. Example analysis showed the correct, novel and practical value of the method.
