DEA算法在公路路线方案评选中的应用

路线方案的评选是公路勘测设计中一项重要的工作，直接影响项目建设能否达到预期目标以及项目投入运营中的使用效果。进行路线方案评选时，要考虑路线的线形合理性、对周边地区的环境影响、项目经济效益、施工难易等多种因素。针对公路路线方案评选的现状，提出一种新的评选方法——DEA算法，并结合实例详细介绍这种算法的应用情况，研究表明该算法在公路路线方案的评选中具有较好的适用性。

The DEA Algorithm Application of the Route Planning Comparison

Road route planning comparison is an important work during the highway design and construction.It has a direct impact on construction projects whether it can achieve the desired objectives,as well as projects in the use of operational results.It is necessary to consider a variety of factors,such as the rationality of the route alignment,the peripheral areas of environmental impact,cost-effective project,and construction difficulty.According to the actuality of the road route planning comparison,one new method is mentioned-DEA algorithm.And introduce the application of the algorithm though a case study.Experimental results demonstrate that DEA algorithm has preferable adaptability.
