摘要
针对层次分析法(AHP)的缺点,提出了一种基于三角模糊数的模糊层次分析法,该评估方法通过使用模糊数来反映专家评判的模糊性,弱化了单纯使用AHP方法存在的主观性,并对网络用户行为各属性的权重进行量化计算,使评判结果更加客观,通过实例说明如何在实际中应用该方法。评价结果为基于动态信任的安全控制提供量化分析基础,为服务提供者采取更加安全的策略来响应用户请求提供量化依据。
The paper proposes a new method to evaluate the user behavior of trustworthy network.The paper elaborates the merits and faults of AHP and proposes a fuzzy analytic hierarchy process method based on the triangular fuzzy numbers in the user behavior trust study.The weights of the user behavior are evaluated and calculated.A simple example is given to show the application of the proposed method.Adopting the evaluation method that can reflect fuzzy evaluation and weaken the subjectivity of AHP makes the results conforming to the Objectivity.According to the quantitative result the method offers,service supplier can take suitable strategy to respond the user requires.
