体育评价中运用灰色关联分析值得注意的问题

Some notable problems on applying grey relation analysis to sports evaluation

运用文献资料法,对体育评价中的灰色关联分析方法进行探究,结果显示:在体育科研领域,灰色关联分析方法经常被用于体育评价,但由于其方法自身存在的特点以及体育评价的特殊要求,应用需谨慎。基于体育评价的要求,结合灰色关联分析法的原理,发现灰色关联分析法的关联度不体现因果关系,关联度不代表重要程度,关联度的不确定性,关联度用于筛选评价指标时的排挤效应等问题。

By using the method of document,this paper probes into the grey relation analysis(GRA)method used in sports evaluation.The results show that in the field of sports scientific research the GRA often is used for sports evaluation,but it should be used carefully for its features and sports evaluation’s special requirements.Considering the requirements of sports evaluation and the theory of GRA,this research finds out relatedness of GRA neither shows causation and result nor representing importance;it has uncertainty;it is used to filter crowding-out effect when evaluates indicators.
