TOPSIS法与局部差异法在高速公路路面使用性能评价中的应用

The application of TOPSIS method and local difference method in the highway pavement performance evaluation

伴随高速公路通车里程的日益增加,养护任务的不断加重,快捷、准确地评价高速公路的使用性能成为必要前提。本研究提出TOPSIS法与突出"局部差异"法相结合来评价高速公路的使用性能。突出"局部差异"法可以根据实际情况来确定指标权重。TOPSIS法可得出评价指标与评价等级的相似程度,从而得出评价路段的使用性能。通过对工程实例的分析,可以快速、准确的得出结果,验证了该方法是可行的。

Along with the increasing highway traffic mileage and the maintenance task,the use of fast and accurate evaluation of the highway performance becomes a necessary premise.In this paper,the combination of TOPSIS and the highlighted local difference method was adopted to evaluate the performance of highways.Th highlighted ＂ local difference＂ method can be used for determining the index weight according to the actual situation.TOPSIS method can be used to gain the similarity degree between the evaluation indices and the evaluation grades and therefore to get the road performance that were evaluated.Through the analysis of engineering examples,The results were acquired rapidly and accurately,which indicated the feasibility of this method.
