摘要
在结合实例进行分析的基础上,指出了传统的灰色平均关联度可能出现的关联度和实际的贴近程度不一致的缺陷。通过引入欧几里德贴近度,建立欧几里德贴近度-灰色关联复合模型,解决了灰色平均关联度的这一不足,并结合石家庄市地表水环境质量评价说明该模型的应用,得到了与实际情况一致的评价结论,表明这一模型是合理和可行的。
Defects of grey average relation grade were discussed based on case study. By the introduction of Euclid approach degree, a complex model of Euclid approach degree-grey relational analysis was established and applied to assessing surface water quality of 3 monitoring points in the city of Shijiazhuang, with results in consistence with the facts.
