摘　　要：提出一种基于服务提供的QoS约束建立直接信任模型的方法,并在建立过程中引入偏序关系,以屏蔽一些在创建过程中没有价值的参考历史纪录.同时参考人类社会行为规律建立推荐信任模型,并借鉴人类竞赛的打分机制屏蔽恶意推荐信息.为了避免出现负载不均衡的现象,提出采用轮盘赌的方法进行服务选择.实验证明该模型能有效地解决问题.A method is proposed to construct direct trust model based on QoS （ Quality of Service） constraints provided by the services, and a partial relation is introduced to shield the worthless history record in the building process. Meanwhile, the recommendation trust model is constructed by referring to the behavior rules of human society, and the malice recommendation information is shielded by using the marking mechanism of contest in human society. In order to avoid load imbalaneing, a service selection based on the method of roulette wheel is adopted. Experiment proves that this model is effective.
