复杂控制因素下的路线敏感节点方案比选研究OA

Taking the route scheme comparison at the sensitive nodes of the Heshan Road West Extension Project Phase I as the research ob-ject,a comprehensive evaluation system for route scheme comparison is established by selecting three main indicators:economic benefits,so-cial environment,and engineering impact.Using entropy weighting method to objectively assign weights to each indicator and determine their weights.Based on the basic principle of cloud model,the evaluation cloud maps of the three schemes are calculated,and compared with the standard evaluation cloud,the evaluation results are visualized,and the optimal scheme is obtained,avoiding the subjectivity of the evaluation process.
