灰色关联投影法在高校助学金评定中的应用

针对目前各高校助学金评定的现况以及传统的评定方法的局限性，提出了灰色关联投影法。首先根据助学金评定的目的与评定的条件，建立科学的评价指标体系并进行合理地量化，然后结合我院19名学生的相关信息，采用灰色关联投影法计算出每位学生的灰色关联投影值，即综合评价值，最后根据综合评价值确定学生是否获得资助以及资助的等级。该方法把模的大小和夹角余弦的大小结合起来，全面而准确地反映出了各决策方案与理想方案之间的接近程度，计算结果反映出了评价的公平合理性。

APPLICATION OF GREY RELATION PROJECTION METHOD IN UNIVERSITY GRANTS ASSESSMENT

In view of the present status of each university grants evaluation and the limitation of the traditional evaluation method, this paper puts forward the grey relation projection method. First of all, according to the purpose of the assessment and the conditions of the grant assessment, scientific evaluation index system is established and evaluation index body is reasonable quantitative. Then with regard to the 19 students of our college, by using grey relation projection method to calculate each student＇s grey relation projection values, that is the comprehensive evaluation value, according to the comprehensive evaluation value determine whether students get funding and funding level. The method of the mold size and the size of the angle cosine combination, comprehensive and accurately reflect the decision scheme and ideal scheme between the proximity, the calculation result reflects the fairness and rationality of the evaluation.
