为使高速公路养护质量评价结果更全面,运用可拓理论,在补充相关评价指标的基础上,建立高速公路养护质量评价的物元模型,结合层次分析法计算得到随评价指标数值大小而动态变化的权系数,通过确定待评物元关于质量等级j的可拓关联度,得到高速公路养护质量等级,最后以东莞市某高速公路为例,验证了该方法的可行性.结果表明:可拓理论与层次分析法相结合的方法适用于高速公路养护质量评价,其评价结果与实际情况相符.
In order to make the evaluation result of expressway maintenance quality more comprehensive, by using extension theory, the matter-element model of expressway maintenance quality assessment is established on the basis of supplementing the related evaluation indexes. The matter-element model of expressway maintenance quality assessment is calculated with the analytic hierarchy process , And obtains the grade of maintenance quality of expressway by determining the relevancy degree of the item to be evaluated with respect to the quality grade j, and finally verifies the feasibility of the method by taking a highway in Dongguan as an example.The results show that: The combination of theory and AHP is applicable to the evaluation of expressway maintenance quality, and the evaluation results are consistent with the actual situation.
