Study On Efficiency Evaluation Of College Graduates Based On DEA Fusion Algorithm

The evaluation method of evaluating graduation students mainly use the weighted integral methods.This approach is largely subjective.In particular,some extracurricular activities in science and technology,student activities have a certain effect on the students' learning weight.There are some disadvantages to using this method.In this paper,Data Envelopment Analysis(DEA)and other statistical methods are used to establish the evaluation method of learning efficiency of university graduates based on Data Envelopment Analysis(DEA).First of all,the size of the output and input Data(i.e.,multiple Data)in the Data Envelopment Analysis model does not affect the evaluation results.Whether it's a five-point system or a 100 system,the result is the same.In addition,different course types can be selected to discuss the learning efficiency,so the DEA model can be used to evaluate the efficiency of college students' graduation study with different courses or evaluation methods.Secondly,when the DEA model for evaluation of data and G-DEA model are failed,comprehensive evaluation of cross efficiency DEA model is established through two strategies of a Self-evaluation and Peer evaluation.This kind of cross-efficiency DEA model can evaluate students 'learning efficiency well.Thirdly,the correlation degree between other courses and graduation design is obtained through grey relational degree method in grey system theory.Select a number of courses that are large correlation degree or small serve as a sample set.That exclude the distortion phenomenon,there are too many distractions.Fourthly,the generalized DEA method based on clustering is used to distinguish the majority of students by clustering.Students of other classes are evaluated by different students and their own "opposites".And it can be ordered completely,so that we can study the students' learning efficiency.In a word,The traditional data envelopment analysis,generalized data envelopment analysis,the cross efficiency data envelopment analysis,clustering data envelopment analysis based on the correlation degree and so on college students' graduation thesis has carried on the evaluation of the learning efficiency.The examples show that these DEA methods have a good evaluation effect on students' learning efficiency.
