摘　　要：如何实现学生诊断是基于Web学习的关键技术,利用现代教育理论,提出了基于多标准判决模糊推理方法,这种方法通过定义不同标准的权数,使得判决算法变成一个矢量与一个矩阵相乘,给出了多标准判决的权数计算公式。与基于if-then规则模糊推理相比,这种方法十分简便、灵活。实验结果表明,其诊断结果十分接近专家的诊断结果。Student diagnosis is a key technology in an education system based on Web.A fuzzy inference based on multicriteria decision-making is presented using modem education theory.The inference becomes multiplication a vector by a matrix by defining the weights of the various criteria.And the closed-form formula of the weights is obtained.The inference is very simple and flexible when compared to a fuzzy inference using if-then rules.Experimental results demonstrate the diagnosis using the inference is closer to the assessment performed by a human expert.
