基于灰色关联分析的系统优势分析

The system superiority analysis based on grey interrelated analysis

灰色系统关联分析法实质上是关联系数的分析。先是求各个方案与由最佳指标组成的理想方案的联系数,由关联系数得到关联度,再按关联度的大小进行排序、分析,得出结论。该方法具有原理简单、易于掌握、计算简便、排序明确、对数据分布类型及变量之间的相关类型无特殊要求等特点,具有极大的实际应用价值。

The interrelated analysis law of grey system is essentially the analysis of interrelated coefficient. Before this beg the interrelated coefficient of the ideal scheme with by the optimum quota forms of each scheme, and by the interrelated coefficient gets interrelated spending. And according to the dimension of interrelated degree carried on row's order again the analysis, reaches the conclusin. Characteristic possesses that the principle is clear and definite and not special requirement of being mutually related type to data distribution type and variable etc, hence possessing very big real application value.
