基于改进多属性决策的铁路车站改建方案评价研究

Research on the evaluation of railway station reconstruction schemes based on improved multiattribute decision-making

为进一步提升铁路车站改建项目方案决策的科学性和有效性,首先在对铁路车站改建方案的主要影响因素进行全面梳理的基础上,构建改建方案评价体系,涵盖地区枢纽适应性与协调性、运输组织及能力、既有营运线干扰、工程可实施性、经济与社会效益5个指标层;然后,提出基于改进多属性决策的铁路车站改建方案评价方法,即区间直觉模糊环境下基于累积前景理论的改进MABAC算法,并考虑在属性权重未知的情况下采用熵权法确定属性权重,以更准确地刻画决策者的心理偏好;随后,给出铁路车站改建方案评价的具体步骤;最后,以某枢纽车站改建为例,采用所提方法对其改建方案进行评价,并将评价结果与实际采用方案以及其他决策方案评价结果对比,对比结果的一致性证明该方法具有实用性和有效性,而且在逻辑上更加贴近现实决策因素,可为铁路车站改建方案的优劣评判提供依据。

To further improve the scientific and effective decision-making of railway station reconstruction projects,the first step is to comprehensively sort out the main influencing factors of railway station reconstruction projects,and establish an evaluation system for reconstruction projects,covering five indicator layers,namely regional hub adaptability and coordination,transportation organization and capacity,existing operating line interference,engineering feasibility,and economic and social benefits;then,a railway station reconstruction project evaluation method based on improved multi-attribute decision-making is proposed,namely the improved MABAC algorithm based on cumulative prospect theory in the interval intuitionistic fuzzy environment,and the entropy weight method is considered to determine the attribute weights in the case of unknown attribute weights,so as to more accurately characterize the psychological preferences of decision-makers;then,the specific steps for the evaluation of the railway station reconstruction projects are provided;finally,taking the reconstruction of a certain hub station as an example,the proposed method is used to evaluate its reconstruction project,and the evaluation results are compared with the actual adopted plan and other decision-making project evaluation results.The consistency of the comparison results verifies the practicality and effectiveness of the method,and the method is logically closer to real-life decision-making factors,which could provide a basis for evaluating the advantages and disadvantages of railway station reconstruction projects.
