摘要
在对灰关联分析法原理分析的基础上,提出了一种新的灰关联系数表达式.与传统的灰关联系数表达式和两种改进的灰关联系数表达式进行了比较,说明新的灰关联系数表达式在理论上是可行的.实例应用表明,基于新的灰关联系数表达式的灰关联分析方法用于水质评价,可以给出较为符合实际的评价结果.
Based on the principle of grey relation analysis, a new expression of grey relation coefficient was proposed. The comparison of the new expression with the conventional one and other two improved expressions shows that the present one is rational in theory. Case study shows that the present expression may provide rational result of water quality evaluation, which agrees well with the reality.
