【摘要】：在鐵路干線能力釋放、鐵路運輸物流化快速發(fā)展的大背景下,分析了鐵路運輸?shù)氖袌鰻顩r,包括鐵路運輸?shù)膬?yōu)勢和短板,分析了電商平臺等互聯(lián)網(wǎng)元素的加入和物流中心的建立對鐵路運輸?shù)挠绊?簡述了鐵路運輸產(chǎn)品應對市場化需要的升級換代。對全程貨物運輸計劃、零散貨物快運和鐵路貨運服務網(wǎng)絡的基礎理論進行了較為詳細的分析,總結(jié)了各自的特點,列舉了快運班列面向的貨物品類,對全程貨物運輸計劃下的快運列車的作業(yè)過程進行了較為詳細的闡述。建立了車流接續(xù)模型,以在站停留時間和運輸費用作為目標函數(shù),加入了班列開行約束、運到期限約束、運行線能力約束。最后在模型中加入了不確定性約束條件,給出了將不確定性模型轉(zhuǎn)化為確定性模型的方法。通過算例對模型進行了較為全面的分析和驗證,從數(shù)據(jù)預處理開始,對車流的拆分方法進行了詳細說明,針對具體情況,定量分析了不同班列最小開行車輛數(shù)和車流在站停留時間的關系,得出了較為合理的班列開行最小車輛數(shù)。模型求解結(jié)果的重點是得出如何對車流進行拆分和如何對車流進行分配,即將每一支由各個技術站產(chǎn)生的初始車流拆分成一個個子車流,然后又將子車流分配到各個班列中去。考慮了車流總量超過路網(wǎng)總能力和未超過總能力的情況,在超過總能力時,根據(jù)求解結(jié)果合理滯留超出路網(wǎng)能力部分的初始車流,在未達到路網(wǎng)能力時,根據(jù)計算結(jié)果安排車流,刪除未分配車流的運行線,再根據(jù)各個初始車流的生成時間,在不改變車流組織的情況下調(diào)整運行圖,使得車流在站停留時間減少。最后加入不確定貨源,得出不同計劃兌現(xiàn)率下的車流在站停留時間以供對比參考。從跨局快運路網(wǎng)中選取京廣快線進行分析計算,對京廣快線沿線技術站的管內(nèi)班列的運輸組織進行分析,得出相應跨局車流運輸需求，，在給定列車時刻表的情況下得出合理的車流組織,并對運行圖進行運行線刪除和調(diào)整。
[Abstract]:Under the background of the release of railway trunk line capacity and the rapid development of railway transportation logistics, the market situation of railway transportation is analyzed, including the advantages and disadvantages of railway transportation. This paper analyzes the influence of the addition of Internet elements such as e-commerce platform and the establishment of logistics center on railway transportation, and briefly introduces the upgrading of railway transport products to meet the needs of marketization. This paper analyzes in detail the basic theories of the whole cargo transport plan, the scattered freight express transportation and the railway freight service network, summarizes their respective characteristics, and lists the categories of goods facing the express transportation classes. The operation process of express train under the whole cargo transportation plan is described in detail. The train flow continuity model is established, which takes the station residence time and transportation cost as the objective function, and adds the train running constraints, the delivery term constraints, and the running line capacity constraints. Finally, the uncertain constraints are added to the model, and the method of transforming the uncertain model into the deterministic model is given. The model is analyzed and verified by a numerical example. Starting from the data preprocessing, the separation method of the traffic flow is explained in detail, aiming at the specific situation. The relationship between the minimum number of vehicles in different trains and the residence time of train flow at the station is quantitatively analyzed, and a reasonable minimum number of vehicles is obtained. The key point of the model solution is how to split the traffic flow and how to distribute the traffic flow, that is, the initial traffic flow generated by each technical station is split into a sub-flow, and then the sub-flow is allocated to each class train. Considering that the total traffic volume exceeds the total capacity of the network and does not exceed the total capacity of the network, when the total capacity is exceeded, the initial traffic flow beyond the capacity of the network is reasonably retained according to the result of the solution, and when the capacity of the network is not reached, According to the result of calculation, the traffic flow is arranged, the running line of the unallocated traffic flow is deleted, and according to the generating time of each initial traffic flow, the operation diagram is adjusted without changing the traffic flow organization, so that the train flow residence time in the station is reduced. Finally, by adding uncertain sources of goods, the stop time of traffic flow at the station under different planned delivery rates is obtained for reference. From the analysis and calculation of Beijing-Guangzhou Express Line selected from the inter-bureau express network, the transportation organization of the in-line train of the technical station along the Beijing-Guangzhou Expressway line is analyzed, and the corresponding cross-bureau traffic flow transportation demand is obtained. The reasonable train flow organization is obtained under the condition of given train timetable, and the running line of operation diagram is deleted and adjusted.
