基于灰关联定权的理想矩阵法及应用

The Ideal Matrix Method Based on the Grey Relation Analysis to Determine Index Weight and Its Application

针对理想矩阵法研究中存在的不足,利用灰关联分析方法,提出了指标权重的确定方法。在指标权重确定的基础上,建立了基于灰关联定权的理想矩阵法,并给出了该方法的计算步骤。通过对我国四个沿海省份2005—2008年期间的交通运输能力评价的实例分析,检验了提出的方法的有效性。

Based on the ideal matrix method of the insufficiency in research, using the gray relation analysis method, the method of determining the index weight is put forward. In determining index weight basis, is established based on Grey ideal matrix method, the calculating steps of the method is given. Through to our country the four coastal provinces 2005--2008 years during the transport capacity evaluation case analysis, the effectiveness of the proposed method is testied.
