基于灰色关联和层次分析法的公路网运行状态评价

摘要

On the basis of comprehensive analysis influence highway network operation characteristics,set up evaluation index system of road net-work running status. In view of the characteristics of highway network,this paper proposes a combined based on the Analytic Hierarchy Process ( AHP)and grey correlation method of comprehensive evaluation. Analytic Hierarchy Process( AHP)is applied in determining weights of indica-tors,using grey correlation analysis method determine the running condition of road network,road network running state evaluation model is set up. Application results show that the evaluation result is objective,the model can be used for road network running status evaluation.%在综合分析影响公路网运行特点的基础上，建立了公路网运行状态评价指标体系，针对公路网的运行特点，提出了一种基于层次分析法和灰色关联相结合的综合评价方法，应用层次分析法确定指标的权重，再利用灰色关联分析法确定公路网的运行状态，建立公路网运行状态评价模型，应用结果表明，评价结果客观合理，所建模型可用于公路网运行状态评价。
