Abstract: Current trust evaluation model exists performance problem. This paper improves the trust evaluation model which is used in Web services environment in order to improve the system performance. Consensus rule provided by the model is used to calculate a new trust degree. Independent trust degree is improved to show the different reflect of independent trust degree to final trust degree. Simulation experiments show the improvement of the model and consensus rule achieves the anticipated results.

Key words: Web services, trust model, trust degree

摘要： 针对当前信任评估模型系统性能低的问题，对Web服务环境中采用的评估模型进行改进，提高系统的整体性能。同时对模型中计算各独立信任度综合信任度的合意运算进行改进，体现各信任度对综合信任度的不同影响程度。模拟实验证明，对模型以及合意运算的改进达到了预期效果。
