根据主观信任的主观性、模糊性和随机性等特点,引入隶属云模型理论对信任进行建模,给出了信任云和信任等级云的定量描述,提出了信任评价云的计算、合成、综合运算和主体信任等级的评估。模拟实验结果表明该信任评估模型是有效的。
According to the characteristics of subjectivity, fuzziness and randomicity in subjective trust, the model of trust evaluation based on membership cloud theory was proposed by introducing the theory of membership cloud. The trust cloud and trust grade cloud were described quantificationaUy, the process of calculation, synthesis and comprehensive operation for the trust evaluation cloud was presented, and the evaluation of trust grade was also presented. The results of experiments show that the trust evaluation model proposed is valid.
