模糊优选教材算法的研究与设计

The research and design on the algorithm of optimize selection teaching material by fuzzy decision

教材质量的评判是选择教材的关键,涉及教材质量的因素较多,且各因素具有模糊性.论文应用模糊数学理论对教材质量评价方法进行了探讨.建立综合评价教材质量的指标体系,利用层次分析法(AHP),通过调整成对比较矩阵,保证其不一致程度在容许范围之内并判断随机一致性比率CR,确定各评价指标的权重,运用二级模糊评价方法对教材质量综合评价进行优选,并结合实例进行综合分析.运用该模型可以对教材质量进行公正、科学的评价.

The key of selection of teaching material was to evaluate the quality of teaching material, many factors were related to the quality of teaching materials, and each factor was fuzzy. The paper discussed a method to evaluate the quality of teaching material by using fuzzy theory. It proposed a set of evaluating indexs to measure the quality of teaching material, and used AHP method to calculate the weight of each evaluating index and by adjusting the pairwise comparison matrix to ensured that the extent of its inconsistency was in permitted range and judges random conformance rate, and then it evaluated quality of teaching material by two levels fuzzy evaluation. So it got quantitative analysis method of AHP--Fuzzy comprehensive evaluation, and which was illuminated by an instance. Using the model could be just fair and scientific to evaluated the quality of teaching material.
