基于灰色关联分析的多级别聚类评价模型的研究

Research on evaluation model of multi -grade classification using grey correlation degree analysis

根据灰色关联分析的性质 ,通过构造灰色系统的目标函数 ,运用 Lagrange乘数法建立了一种新的灰色聚类评价模型 ;还给出了时间序列的灰色绝对关联度系统评价算法 ,较好地解决了多因素、多指标、多级别的系统综合评价问题 .

According to the characteristics of grey correlation degree analysis, a new kind of evaluation model of multi grade classification is put forward by using L multiplier and structuring objective function. Also, the more profound evaluation algorithm of grey correlation degree on the time subsequency is obtained. The multi factor, multi quota, and multi grade evaluation problem is solved favorably.
