基于综合权重的模糊层次风险评估方法

The Method of Risk Assessment using FAHP based on Synthesized Weights

为更加真实的反映信息系统的总体风险水平,加强准确性,降低判断中主观因素的影响,本文将运用不确定型层次分析法(AHP)、模糊综合判断和熵权相结合的方法,对信息系统进行风险评估计算,以区间值的形式反映信息系统的风险状况。实例结果表明,该方法能较客观、真实、准确的评估信息系统风险情况。

For the purpose of more truly reflecting risk level of information system,enhancing assessment accuracy and reducing subjective effect in judgment,this paper uses the combinative method of analytic hierarchy process（AHP） ,fuzzy comprehensive judgment and entropy to calculate the risk.The risk state of information system is reflected in the form of interval value.Experiment result proves that the method can provide truer,more objective and accurate risk assessment on information system.
