Abstract: Students comprehensive evaluation is one of the most practical significance work of student management. Traditional students comprehensive evaluation is completely manual statistics and analysis It wasted a lot of time and manpower, the efficiency is very low. Together with strong subjectivity and complicated index system, it’s easy to make a mistake, and hard to ensure objectivity and impartiality of the assessment. The paper based on Intuitionistic Fuzzy Sets (IFS) theory established a multi-level students comprehensive evaluation model. Integrate qualitative and quantitative methods for students comprehensive evaluation. It’s scientific and fair, have a high degree of automation. Then analyzes the model’s calculation complexity. Combined with an example of a class of ShangLuo university giving a comprehensive evaluation. The result shows that the model is effective and practical. 关键词：直觉模糊集; 综合考评; 加权函数; comprehensive evaluation; weight fuction 中图法分类号: G304 文献标识码: A 1.引言 学生综合考评是学生管理中最具实际意义的工作之一. 传统学生综合考评完全是手工统计分析, 费时费力效率低下. 考评过程以及复杂的考评结果分析常常令学生管理人员感到沮丧和难以把握. 加之主观性强及指标体系复杂性, 容易出错, 难以保证考评的客观性和公正性. 这样就出现了学生管理人员与学生间一些矛盾和问题, 在不同程度上影响到了学生考评工作发挥其应有的作用, 甚至对学生管理产生负面影响. 直觉模糊集[1-3]（Intuitionistic Fuzzy Sets缩写为）理论由保加利亚学者K.T.Atanasssov于1986年提出, 以其深刻的理论意义, 和广泛的实际背景; 已被用于系统评价相关的各个领域[4-7]. 评价的难点是评价指标的选择尤其是评价等级与其权重的确定[8-10]. 文章基于直觉模糊集理论建立了一个多级学生综合考评模型; 将定性与定量的方法结合起来对学生综合
