一种基于AHP和模糊理论的风险评估方法

A Risk Assessment Method Based on AHP and Fuzzy Theory

AHP方法是一种重要的多评价集分析方法,它在决策领域得到广泛的应用。本文将AHP方法和模糊理论相结合,设计了一套新的信息系统风险评估方法。使用该方法,本文对一个具体的风险评估实例进行了分析。结果表明,该方法可以较好地解决评估中不易量化和主观性的一些问题,从而可以提高评估结果的科学性与合理性。

AHP （Analytic Hierarchy Process） is a important multi appraisal method and gain comprehensive applications in the field of decision. Combining AHP method with fuzzy theory, a new information system risk assessment to conquer the problem of risk factor quantify and subjectivity is proposed. With such method, we analyze a risk assessment example. The result shows that the method can better solve the problems which are subjective and not easy to be quantized, thus improving its science and feasibility.
