基于超效率DEA的地铁初近远期编组方案比选研究
Research on Comparison and Selection of Subway Formation Scheme in Initial,Near and Long Term Based on Super-efficiency DEA
摘要
Abstract
The marshalling scheme is the foundation to match the operation mode and passenger flow characteristics of metro in different periods,and it is also the key problem that directly affects the cost of metro planning and construction and low-carbon operation.Based on the comprehensive analysis of the key factors affecting the metro marshalling scheme,a comprehensive evaluation index system and a two-step screening method are established.Based on the analysis of the difference of the impact of each index on the metro marshalling plan,a new evaluation model of the metro marshalling plan in the early and near future based on super-efficiency DEA is proposed.Finally,the feasibility and rationality of the evaluation and comparison model of the early,near and long-term subway marshalling scheme are verified and analyzed by examples.The results show that:(1)The fixed marshalling plan is a cost-energized plan,which requires higher equipment cost and operation input,while the modified marshalling plan is a technology-energized plan;by improving the management and technical level,the effective output of capacity matching and passenger time satisfaction can be achieved.(2)The advantages and disadvantages of modified marshalling scheme and fixed marshalling scheme are dynamic to a certain extent,comprehensive judgment should be made according to the specific conditions of the line,the financial situation of the city or enterprise,the operation management and the technical level.The theoretical method of comparison and selection of early,near and long-term metro marshalling schemes presented in this paper is applicable to many practical scenarios and has certain practicability,which can provide certain theoretical reference for the standardization of comparison and selection of early,near and long-term metro marshalling schemes.关键词
