基于Entropy-FAHP综合定权法的山区公路路线方案优选研究

Study on the Optimization of Mountain Road Route Scheme Based on Entropy-FAHP Integrated Weighting Method

针对山区公路选线评价主观分析多、定量少的问题,为综合量化评价比选方案状况,建立了三维度多指标的山区公路路线评价体系,并将Entropy法与FAHP法进行有机结合,构建了山区公路路线多方案综合评价方法,采用该方法对定西市某公路K线和A线2个方案进行评价,计算各方案综合权重下的得分,得到了贴近工程实际的优选方案。

Aiming at the problem of subjective analysis and less quantitative evaluation of mountain road selection,a comprehensive evaluation system for mountainous roads with three dimensions and multiple indicators was established for the comprehensive quantitative evaluation of the comparison plan.The Entropy method and the FAHP method were organically combined and constructed.The comprehensive evaluation method for multi-programs of mountain road routes was adopted to evaluate the two schemes of K-line and A-line of a highway in Dingxi City,the scores were calculated under the comprehensive weight of each scheme,and the optimal scheme close to the actual project was obtained.
