摘　　要：针对公路路线方案综合评价的多目标、多层次等特点,运用多层次灰色理论的方法,对可比性方案通过综合评价选出最优方案.通过对路线方案因素指标分层及参考数据的确定,采用层次分析和灰色理论相结合的方法,对各层指标相对权重进行了确定和检验.借助灰色关联分析,计算了公路路线方案的综合关联度.根据关联度越大排序越前的原则,确定最优方案.In view of the characteristics of multi-targets and multi-layers in evaluating route plans,the multi-levels grey system is applied to the evaluation system to select the most superior scheme from the comparable plans.According to the lamination of indices of route plan and determination of reference data,the analytic hierarchy process combined with grey system theory to decide and test the relative right weight of every index in the evaluating system.The synthetically grey related degree of every plan is ca...
