【摘要】:京滬高速鐵路自開通運營以來,以其大運量、高速度、高舒適性的運輸特點,吸引了大量京滬通道內的客流,很大程度上緩解了通道內的運輸壓力,也逐漸形成了其特有的客流規(guī)律。與此同時,沿線區(qū)域經濟在快速發(fā)展,與民航、公路的競爭也日趨激烈,同時還不斷有新建成的線路接入京滬高鐵路網,在這些條件的作用下,使得通道內的客流量、客流結構不斷發(fā)生變化。這就要求京滬高速鐵路客運開行方案等核心產品設計要不斷適應市場變化與需求,能夠及時做出優(yōu)化調整。在此背景下,本論文以京滬高速鐵路為研究對象,研究一種滿足京滬高速鐵路運營需要的開行方案評價與優(yōu)化調整方法,使企業(yè)能夠根據運營效果及時對客運產品做出評價及調整。 首先,論文以現有的車、流、票等歷史數據和準實時數據為基礎,從時間、空間等多個維度,深入分析了京滬高鐵的客流規(guī)律。為京滬高鐵開行方案評價及優(yōu)化調整提供了的數據基礎和決策依據。 其次,遵循開行方案評價指標體系建立原則,分析了開行方案的影響因素,研究建立了面向京滬高速鐵路開行方案的單列車評價指標體系和整體性評價指標體系,并給出評價指標的計算方法。 再次,在比較分析現有開行方案綜合評價方法的基礎上,研究提出了一種基于聚類-主成分分析的兩階段綜合評價方法,即首先對單列車進行基于聚類-主成分分析的評價和調整,再通過對整體方案進行分層分析做補充調整的綜合評價方法,并給出具體評價的流程和步驟。 然后,以京滬高速鐵路開行列車為實際對象,針對單列車進行了主成分分析,得出評價主成分即為企業(yè)經濟效益和旅客出行服務水平。在此基礎上,對問題列車進行了評價,并給出調整建議。 最后,對整體開行方案各層次指標進行了分析評價,補充了單列車因主成分分析造成信息損失的不足,完善了開行方案評價的系統(tǒng)整體性。
[Abstract]:The Beijing-Shanghai high-speed railway has attracted a large number of passengers in the Beijing-Shanghai corridor because of its characteristics of large volume, high speed and high comfort since it was put into operation. To a great extent, it has alleviated the transport pressure in the channel. Also gradually formed its unique passenger flow law. At the same time, with the rapid development of the regional economy along the route, the competition with civil aviation and highways is becoming increasingly fierce. At the same time, there are constantly new lines connected to the Beijing-Shanghai and Shanghai high railway network. Under these conditions, the passenger flow in the passageway is made. The structure of the passenger flow is constantly changing. This requires that the design of core products such as the Beijing-Shanghai high-speed railway passenger transport development plan should be constantly adapted to market changes and needs and be able to make timely optimization and adjustment. Under this background, this paper takes the Beijing-Shanghai high-speed railway as the research object, studies a kind of plan evaluation and optimization adjustment method to meet the needs of the Beijing-Shanghai high-speed railway operation. To enable enterprises to make timely evaluation and adjustment of passenger transport products according to operational results. Firstly, based on the existing historical data and quasi-real time data, the paper deeply analyzes the rules of passenger flow of Beijing-Shanghai high-speed railway from time, space and other dimensions. It provides the data basis and decision basis for the evaluation and optimization adjustment of Beijing-Shanghai high-speed railway. Secondly, in accordance with the principles of establishing evaluation index system of bank opening scheme, this paper analyzes the influencing factors of the operation plan, and studies and establishes a single train evaluation index system and an overall evaluation index system for Beijing-Shanghai high-speed railway operation plan. The calculation method of evaluation index is also given. Thirdly, a two-stage comprehensive evaluation method based on clustering and principal component analysis is proposed on the basis of comparing and analyzing the existing comprehensive evaluation methods. That is to say, the single train is evaluated and adjusted based on clustering principal component analysis (PCA), and then the comprehensive evaluation method based on stratified analysis of the whole scheme is introduced, and the process and steps of the evaluation are given. Then, taking the Beijing-Shanghai high-speed railway train as the actual object, the principal component analysis is carried out for the single train, and it is concluded that the evaluation principal component is the economic benefit of the enterprise and the level of passenger travel service. On this basis, the problem train is evaluated and the adjustment suggestions are given. Finally, the indexes of each level of the whole operation scheme are analyzed and evaluated, which complements the deficiency of information loss caused by the principal component analysis of a single train, and improves the system integrity of the evaluation of the operation plan.
