Evaluation And Improvement For The Operation Of Urban Rail Transit Based On DEA

Since the October 1969 opening of Beijing China's first urban rail transit lines.to the end of 2005, has been in Beijing, Tianjin, Shanghai, Guangzhou, Dalian, Shenzhen, Changchun, Wuhan, Chongqing, Nanjing and so on dozens of cities built rail transit lines operating , The total length of lines nearly 500km, according to experts predict that in the next 10 years, China's Urban Rail Transit operators mileage will reach about 1000km.As the Urban Mass Transit costly, a line of at least several billion into building as many as tens of billions, are often the largest infrastructure project. Moreover, construction of urban rail transit network are generally sustained for decades or even centuries on the enormous project, so be it in the intensity or timing of the city's economic development will have an enormous impact. So do the following two aspects are very important to our urban rail transit construction and development will have a very active role: first, before the construction of urban rail transit system planning; second, built and put into service to keep To improve the evaluation.This article is based on the second side. Due to the enormous scale of urban rail transit, was generally no longer be able to re-construction and demolition, built in the line, on a regular basis to evaluate the analysis of constraints line to identify the key factors, and then be improved.The main thesis made two DEA evaluation. The first is urban rail transit sites in all of the evaluation of the change, in this case is the use of the Guangzhou Metro Line One of the 16 stations, through the establishment of urban rail transit station based on the evaluation of the transfer of the DEA model to calculate the 16 stations The evaluation of the efficiency of transfer targets as well as the transfer rate of redundancy input and output rate of deficit, and then in accordance with the decision-making unit in the production of cutting-edge projection surface theory to calculate the effectiveness of the DEA did not reach the station by the need to improve the direction and improved step . The second aspect to the opening of China's current urban rail transit of 8 major cities in the actual operation as an example the case, first of all an analysis of urban rail transit operators evaluate the need, and then through the operating efficiency and cost analysis of the selected input 4 5 output targets and indicators, and then through the establishment of urban mass transit system based on evaluation of the operations of the DEA model to calculate the 8 urban rail transit system operators operating effectiveness of the index and the rate of redundancy input and output rate of deficit, according to the input redundancy Rate and output rate to calculate the deficit did not meet the validity of the DEA's urban mass transit systems to improve operations and improve the direction of the step, the last of the DEA did not meet the validity of the city's rail transit system operating improvements were made related to Analysis and recommendations.
