根据已有灰统计白化函数的局限性,考虑采用改进的灰统计方法。由原始的自动控制原理8个实验成绩构造灰统计样本矩阵,给出改进灰统计的白化函数,得出每个学生的成绩对各统计灰类的单元决策系数和综合决策系数,由这两个系数计算每个学生的成绩对各统计灰类的决策权,由灰类决策权向量判断每个学生的成绩所述的统计灰类,即可判定学生的成绩。与已有的灰统计方法相比更具有合理性。
According to the limitations of existing gray statistics whitening function, consider the use of improved gray statistics. By the original automatic control theory, eight experimental results are used to construct the gray statistical sample matrix, and the whitening function to improve the gray statistics is given. The unit decision coefficients and comprehensive decision coefficients of each student’s grades for each statistical gray class are obtained. Coefficient Calculate the score of each student on the statistics of the gray decision-making power, gray decision-making vector to determine the score of each student’s gray level of statistics, you can determine the student’s performance. Compared with the existing gray statistical methods more reasonable.
