Reaserch On Urban Rail Transit Operation Organization And Relevant Problems

With the developmental steady rapidity of the economy, the acceleration of the urbanization proceedings, as well as the deepening of the mechanization, here comes a significant rise in the heavy traffic in large and medium-sized cities and comes up the increasingly serious problems, which has set back the national economy and become the social extensive focus of all ranks of the government and the commons. Hence, developing the urban mass transit (UMT) becomes the efficient access to resolving it. To programme scientifically and rationally the operation of the UMT is the crux of the matter of giving full play to it. This thesis, in the light of the problems of the operation program of the UMT, conducts research.Analysis of this thesis is set on the factors affected by the operating of the UMT, and main stress is placed on the scheme of locomotive working system, stop and the train formation, on the base of which the model of the operation scheme of the UMT is correspondingly established.This thesis, on the foundation of fully drawing on the experience of relevant study, sysmatically concludes these locomotive routings'features and their applicated conditions, and by utilizing of the AHP and fuzzy method sets up the alternative models. And then, the author analyzes sorts of the stop programmes, discusses the merits and faults, and constructs the multiply targeted-optimized the model, aimed at saving most time for passengers and costing least trains, giving out the corresponding algorithms.Afrer researching the locomotive routings, the formation scheme,the stop scheme and all relevant interfering factors, systems distinguished by the index:delivery capacity, velocity, train utilization, economic benefits, and service, is built. The thesis establishes such a comprehensive evaluating system of the AHP method, fuzzy method and the grey system theory to evaluate and alter the operation scheme of the UMT.
