摘要
针对交通线路方案多目标性特征,从经济、技术和环境等方面构建了交通线路方案评价指标体系,采用灰靶模型对待选方案进行评估和筛选.鉴于传统灰靶模型采用等权的计算方式,本文引入熵权对模型加以改进,由此建立了基于熵权的改进后灰靶模型.交通线路方案比选的结果表明,该方法计算简洁、实施高效,具有一定的推广应用价值.
According to the multi -objective of traffic line scheme, the index system of traffic line was established considering economy, technology and environment etc, then the grey target model was used to evaluate traf-tic line schemes. In view of traditional grey target model using equal weight, entropy weight was introduced to this model, and an improved grey target model was built. The results show that the proposed model is simple and effi-cient, and has a potential market.
