摘要
各类学校学生的奖学金评定中，传统的总分或平均分排名评定法，都因专业，年级、课程、考试试题的深度和难度及评卷教师不同，带来较多的不合理性。文章从极值标准化入手，确定模糊评定等级、隶属度函数、权重集，运用夹角余弦法建立模糊相似矩阵再改造为等价矩阵，最后进行聚类分析。克服了上述合理性。
In the evaluation of scholarships of different schools,the tra
ditional evaluation ie ranking students on the base of their total or average po
ints brings much unreasonableness due to different majors grades curricula,the d
epth and difficulty of tests as well as marking teachersStarting from extremum
standardization,the article defines ranks of fuzzy evaluation,subordinate functi
ons,weight sets,it establishes fuzzy similar matrices by applying angle cosine a
nd changing them into equivalent matrices,then it makes cluster analysisThe pr
o
udure overcomes the above mentioned unreasonableness and obtains satisfactory re
sults
