基于SBM的大型高铁枢纽站安检互认方案评价

Evaluation of Security Mutual Recognition Scheme for Large High Speed Rail Hub Stations Based on SBM

安检互认能够提高不同交通方式间的换乘效率及服务水平,尤其对于大型枢纽高铁站,实行合理的安检互认方案更有助于提升交通出行一体化程度。为分析、量化大型高铁枢纽站与航空、地铁间换乘效率的影响因素,从资源投入与效益产出的角度,剖析换乘中的显性与隐性成本投入,选取了涵盖经济、人力、管理3方面的输入指标,并将实行安检互认对车站及乘客的优劣之处投射到具体指标中,得到包含期望与非期望产出的输出指标,从而构建了安检互认方案效率的评价体系。为使不同安检互认方案构成完整的系统,对其基础流程进行了划定,得到了4种基础安检互认换乘流线。鉴于该问题的特点及多投入、多产出指标体系,建立了基于松弛变量测度(slacks-based measure,SBM)评价模型。最后以兰州西站与中川机场、兰州轨道交通的换乘为例进行安检互认方案假设,应用指标体系及模型评价分析。结果表明:中川机场—兰州西站单向免检、兰州西站与轨道交通间的单、双向免检,均为投入-产出有效方案,最终通过对比分析3种有效方案的投入-产出水平,分别从成本控制最低、非期望产出最小及车站经济收益最大角度给出决策建议与参考。

Mutual recognition through security checks can improve the transfer efficiency and service level between different modes of transportation,especially for large hub high-speed rail stations.Implementing a reasonable mutual recognition plan through security checks is more conducive to improving the integration of transportation and travel.In order to analyze and quantify the influencing factors of the transfer efficiency between large-scale high-speed rail hub stations,aviation and subway,the explicit and hidden cost input in the transfer was analyzed,and the input indicators covering economic from the perspective of resource input and benefit output,which manpower and management were selected and the advantages and disadvantages of the implementation of mutual recognition of security checks on stations and passengers were projected into specific indicators,and output indicators containing expected and undesired outputs were obtained so as to construct an evaluation system for the efficiency of the security inspection mutual recognition program.In order to form a complete system of different security mutual recognition schemes,the basic processes were delineated,and four basic security mutual recognition transfer flow lines were ultimately obtained.Based on the characteristics of this problem and the multi input and multi output indicator system,a slacks-based measure(SBM)evaluation model was established.Finally,taking the transfer between Lanzhou West Railway Station,Zhongchuan airport and Lanzhou rail transit as an example,the mutual recognition scheme of security inspection was assumed,and the index system and model were applied for evaluation and analysis.The results show that the one-way inspection exemption from Zhongchuan airport to Lanzhou West Railway Station,and the one-way and two-way inspection exemption between Lanzhou West Railway Station and rail transit are all effective input-output schemes.Through the comparative analysis of the input-output levels of the three effective schemes,the decision-making suggestions and references are given from the perspective of minimum cost control,minimum unexpected output and maximum economic benefits of the station.
