| 摘 要： | 为了准确地评价信息系统风险,提出了一种融合模糊层次分析法和灰色评估方法的新模型.从“灰度”概念出发,建立信息系统风险灰色评估模型,消减评价者的主观性.在此基础上引入模糊层次分析法,该方法通过引入模糊数学的有关概念对权重的确定方法进行改进,确保了权重选择的客观性.对信息系统风险的实证进行了研究,实验结果表明了该方法的有效性,为进一步提高信息系统风险评估的准确性提供了可参考的模型和方法支持.

| Abstract: | To evaluate the risks of information system,a new model which combined fuzzy-AHP method and grey evaluation method is proposed.Firstly an information system grey evaluation model is proposed from the concept of "grey degree" to reduce the subjectivity of the evaluators.Fuzzy-AHP method is used,concept of fuzzy mathematical is introduced for determining the weight,and this can ensure the objectivity of the weight selection.The demonstration research proves the method is effectively,the study offered referenced model and method for improving the accuracy of risk assessment. |
