摘　　要：在高速公路网布局中,节点层次划分是一个重要的内容.利用重要度法的指标因素,提出一种基于偏好效用分解的节点分类方法.通过已经分类的参考集,建立线性规划模型求得参考集中的对象在各准则值的效用以及分类效用域值,利用线性插值求出待分类对象的边际效用值,进而求出总效用值,根据总效用值和分类域值的比较,可得待分类对象的类别.对河南省的高速公路网布局中的节点分类作了实证研究.The classification of node is an important part in expressway network design. Utilizing the criteria of node importance approach, an approach based on preference disaggregation was proposed. First, through the classified reference set, a linear programming model was proposed to obtain the marginal utility values of alternatives in reference set and the classification utility thresholds. Then, through the linear interpolation, the marginal utility values of alternatives to be classified were attained. And then, the global utility values of alternatives were obtained. Comparing the global utility values with classification utility thresholds, all of the alternatives were classified. Finally, we made a study on the node classification in Henan province expressway network design.
