| 摘 要： | 针对水稻品种优选的DTOPSIS方法中权重给定的主观性，提出利用灰色关联度来确定权重的方法。所获得的评价矩阵无量纲化，然后计算性状的关联度矩阵，并用列和归一化方法导出权重，进而利用DTOPSIS方法对水稻品种排序、择优。

| Abstract: | In response to the subjectivity of weight given in DTOPSIS method of rice preference,a method utilized for Grey Correlation Degree was proposed to determine the characters'weight.This method normalized the evaluation matrix at first,and then the grey correlation matrix was calculated so that the weight will be derived by the normalized column sum method.After that,the rice varieties can be selected and sorted by DTOPSIS method. |
