摘要
将多目标方案比选中常用的层次分析法(AHP)与灰色关联度法有机结合起来,并用于夏蓉高速公路改扩建工程方案优选.以AHP法求出准则层各评价指标权重,以灰色关联度法求出2种备选方案中各评价指标与最佳指标的灰色关联度,最终以评价得分确定优选方案.
AHP (analytic hierarchy process )and grey relational grade method are widely used in the multi-objective complex scheme comparison.In this paper AHP was combined with the grey relational grade method which was applied to figure out the optimization of the Xiarong express-way reconstruction.AHP method was used to obtain the weight coefficient of each evaluation in-dex.Grey correlation degree method was used to calculate the grey relational grade between each alternative evaluation index and the best index.Finally the optimization scheme was determined according to the evaluation score.
