摘要
随着都市圈城市化进程的不断推进,国家对重点城市群、都市圈城际铁路、市域(郊)铁路的规划建设给予了高度重视。由于不同的都市圈城际铁路存在制式需求的多样性,制式选择对其运输效率和城市发展具有重要影响。本文旨在为都市圈城际铁路制式选择提供一个综合决策模型,模型综合运用AHP层次分析法和熵权评估法。首先,通过专家打分确定评估指标的主观性加权,然后利用熵权评估法确定客观加权,从而解决AHP方法的一致性问题。接着,将主观和客观加权相结合,得出综合加权结果。为了提高决策的准确性,针对TOPSIS方法的局限性,提出一种新的改进方法,采用几何距离和灰关联度相结合的方式,以浙江省某条都市圈城际铁路为研究对象,基于基础资料和运营预测数据,提出5个备选制式方案,选取技术性能、工程建设、运营管理和社会环境四个准则,共13个指标。应用构建的决策模型对其系统制式进行评估和优选,经过综合评估,选出以市域C型车为车辆选型及系统集成的系统制式方案作为最优选方案。本研究为都市圈城际铁路系统的规划和建设提供了科学的决策依据。
With the continuous advancement of urbanization in metropolitan areas,the national government has placed high emphasis on the planning and construction of key urban agglomerations,intercity railways in metropolitan areas,and suburban railways.Due to the diverse system requirements of different metropolitan intercity railways,system selection has a significant impact on both transportation efficiency and urban development.This study aims to provide a comprehensive decision-making model for the system selection of intercity railways in metropolitan areas.The model integrated Analytic Hierarchy Process(AHP)and entropy weight method.Firstly,expert scoring was used to determine the subjective weighting of evaluation indicators,and the entropy weight method was applied to determine the objective weighting,thereby solving the consistency problem of the AHP method.The subjective and objective weightings were combined to obtain the comprehensive weighting results.To improve decision-making accuracy,this study proposed a new improved method to address the limitations of the TOPSIS method by integrating geometric distance and grey relational analysis.Using an intercity railway in Zhejiang Province as a case study,this study developed five alternative schemes based on basic data and operational forecast data and selected four evaluation criteria,including technical performance,engineering construction,operation management,and social environment,with a total of 13 indicators.The proposed decision-making model was applied to evaluate and select the system.Through comprehensive evaluation,the scheme of type C intercity trains as the vehicles with integrated system was selected as the optimal solution.This research provides a scientific decision-making framework for planning and developing intercity railway systems in metropolitan areas.
