摘要: 为提高风险评估的可信度,针对传统的层次分析法在确定因素权重方面存在的问题,引入梯形模糊数来确定权重,提出了基于梯形模糊层次分析法的综合评价方法,解决了风险评估中定性指标定量评估的难题。通过实例分析,验证了该方法的合理性和可行性。

Abstract: In order to enhance the credibility of the risk assessment information,aiming at the problem of Analytic Hierarchy Process(AHP) when ascertaining the weighting,using the trapezoidal fuzzy number to ascertaining the weighting and comprehensive information security risk assessment method based on the trapezoidal fuzzy AHP is proposed.It solves the difficulty when conducting quantitative evaluation of qualitative assessment in risk assessment.Finally,an instance of the risk assess is given to show the rationality and feasibility of the results by analyzing the information system.
