摘要
针对传统信任模型的不足,提出了以灰色系统理论为基础的多属性综合信任评价模型。模型通过定义信任评价等级灰类及其白化权函数,计算网络实体各个属性的灰色评价权,结合层次分析法计算属性权重,最后给出实体灰色综合信任值及信任等级灰类。实例表明,该模型计算简便、评价可靠,为网格环境下解决多属性综合信任评价问题提供了新的方案。
Aiming at the deficiency of traditional trust model, this paper put forward evaluation model of multi-attribute comprehensive trust based on gray system theory. Via defining grade of gray cluster and white-nization weight function of trust evaluation, computing gray evaluation weight of each entity in Web and attribute weight through analytic hierarchy process, presen- ted gray comprehensive trust value and grade of gray cluster of the entities finally. Practical examples show that the model is not only good at computing and evaluating , but also provide a new method to solve evaluation problem of multi-attribute comprehensive trust in grid.
