摘要
提出了一种基于数据包络分析(DataEnvelopmentAnalysis,简记DEA)的新的加权灰色关联分析方法。该方法综合了DEA和灰色关联分析两种方法的优势,以灰色关联分析为中心模型,以DEA模型为辅助模型,通过DEA模型来确定每一个子因素各点关联系数的权重向量,从而计算出相对最优的关联度,实现对各因素客观的优先排序。基于DEA方法的加权灰色关联分析方法既克服了确定权重时的主观性,又通过"非均一"赋权达到了优先序评价的"最优性",从而实现了分析结果的"公正性"。最后通过绿色产品的评价实例说明了方法的有效性。
A new method called weighted gray correlational analysis method based on DEA (Data Envelopment Analysis) is presented.It integrates favorable aspects of both DEA and gray correlational analysis,and takes gray correlational analysis as a central model and DEA as auxiliary model.DEA determines the weight vector of correlation coefficients for each subfactor to calculate the relatively optimal correlation degrees and then realizes the priority order of each subfactor by them.The weighted gray correlational analysis method based on DEA not only overcomes the subjectivity when the weight vector is determined,but also gets the optimality of the prior order evaluation by nonuniform weight.By this way,its fairity of the analyzing result is shown.Finally,an example of green products assessment is given to prove its validity.
