摘　　要：传统的层次分析法的“1～9标度”方法不能精确的反映人的实际思维,尤其是在构权时可能会影响最终的判断结果,本文提出了一种基于三角模糊数表示的改进的AHP标度方法,使AHP构权更加符合人的比较思维。最后本文给出入侵检测系统评估指标体系构权实例,结果证明,与传统方法对比,应用三角模糊数方法构权能够更加精确的反应人的实际思维。An improved scale method based on trigonometrical fuzzy numbers was proposed in this paper, because of the inability of traditional ＂1-9 scale＂ method to reflect the real thought accurately ,especially to make important weights which may lead up to incorrect result. An example of evaluation index system of intrusion detection systems is used to illustrate the proposed approach finally.
