Research On Mathematical Modeling Methods For Students Comprehensive Evaluation Based On Cloud Model

With the rapid development of China's higher education,to choose the talent requirements also more and more high,how to make scientific and reasonable to the students' comprehensive quality evaluation is a worth studying further.Evaluate the students need to consider many factors,and the effect of factors on the students' growth is different,so you need to set up a corresponding evaluation index system and to determine the index weight,a reasonable evaluation method on the basis of the formation.This paper makes a comparative study of common comprehensive evaluation methods,such as weighted average method,grey relational analysis method,principal component analysis(PCA)and Fuzzy Comprehensive Evaluation method,Fuzzy Comprehensive Evaluation),such as Fuzzy consistency matrix and Fuzzy Comprehensive Evaluation is proposed combining Fuzzy Comprehensive Evaluation method,and the cloud model is introduced into the new Fuzzy Comprehensive Evaluation,Fuzzy Comprehensive Evaluation model based on cloud model is established.Through entropy and entropy to quantify the evaluation of randomness and fuzziness in the process of description,the boundary is not clear,multidimensionality,fuzziness and uncertainty factors fuzzy quantification,makes a description of the evaluation results more objective and more close to actual situation,through the classification of the various evaluation factors and weights adjustment of fuzzy relations are processing and synthesis,explore a kind of effective comprehensive evaluation method to the student,and will build the model used in a certain university college class of 2015 students,filtering,and the main indexes,combined with the related domain expert experience,optimize the selected indicators set,get the corresponding key indicators,on the basis of students' comprehensive evaluation index system is established,and the model is verified.The results show that the method is effective.
