【摘要】:隨著國家經(jīng)濟的不斷發(fā)展和小件貨物運輸市場的競爭日趨激烈,鐵路行包運輸作為小件行包運輸?shù)闹袌粤α?正在面臨新形勢、新機遇的挑戰(zhàn)。在鐵路行包運輸調(diào)度現(xiàn)代化、市場化的大背景下,以往的以人工經(jīng)驗為主的行包調(diào)度模式亟待改變。研究如何將鐵路行包運輸調(diào)度從生產(chǎn)型調(diào)度向經(jīng)營型調(diào)度轉(zhuǎn)變,實現(xiàn)對內(nèi)管理和對外服務(wù)的雙贏具有重要的現(xiàn)實指導(dǎo)意義。 本文以鐵路行包運輸調(diào)度的指揮體系和調(diào)度過程為研究對象,結(jié)合鐵路行包運輸基本裝運原則,研究了三級調(diào)度體系的職能和相互關(guān)系的優(yōu)化,并從裝運實施方案的優(yōu)化出發(fā),重點研究了直達行包和中轉(zhuǎn)行包裝運組織的調(diào)度優(yōu)化問題。 首先,基于現(xiàn)有鐵路行包調(diào)度體系結(jié)構(gòu)和職能,深入分析了行包調(diào)度指揮的業(yè)務(wù)流程和管理流程,提出了調(diào)度優(yōu)化的必要性和主要優(yōu)化問題。其次,針對行包調(diào)度指揮存在的主要問題,從統(tǒng)計分析、監(jiān)控預(yù)警、運能調(diào)配三方面對三級調(diào)度部門職能分別優(yōu)化。在此基礎(chǔ)上,運用系統(tǒng)優(yōu)化理論優(yōu)化了調(diào)度信息傳遞流程,并給出了行包調(diào)度指揮信息平臺初步架構(gòu)。然后,針對直達行包裝運實施問題,從直達裝運車次的優(yōu)化選擇和分車次裝車計劃調(diào)度調(diào)整兩方面進行優(yōu)化。在分析裝車計劃調(diào)整的影響因素基礎(chǔ)上,構(gòu)建了分車次調(diào)度調(diào)整優(yōu)化模型,以解決在裝運行包廣義收入最大的優(yōu)化目標前提下,同時兼顧貨物裝運優(yōu)先等級的問題。運用lingo12.0編程求解案例,給出各站實際裝車計劃調(diào)整結(jié)果。最后,針對中轉(zhuǎn)行包裝運調(diào)度的決策,給出中轉(zhuǎn)裝運車次的銜接優(yōu)化選擇策略。通過中轉(zhuǎn)決策指標體系的架構(gòu),依托模糊數(shù)學思想,提出了運用改進的多級模糊綜合評價方法來輔助決策,并結(jié)合大客戶行包轉(zhuǎn)運實例驗證了此方法的科學性。
[Abstract]:With the development of national economy and the increasingly fierce competition in the market of small goods transportation, railway luggage and parcel transportation, as the backbone of small package transportation, is facing the new situation, new opportunities and challenges. Under the background of the modernization and marketization of railway luggage and parcel transportation scheduling, the former manual experience oriented luggage and parcel scheduling mode needs to be changed urgently. It is of great practical significance to study how to change the dispatching of railway luggage and parcel transportation from production dispatching to management scheduling, and to realize the win-win situation of internal management and external service. This paper takes the command system and dispatching process of railway luggage and parcel transportation as the research object, combining with the basic shipping principle of railway luggage and parcel transportation, studies the optimization of the function and interrelation of the three-level dispatching system, and proceeds from the optimization of the shipping implementation scheme. This paper focuses on the scheduling optimization of direct package and transit package shipping organization. Firstly, based on the existing railway packet scheduling architecture and functions, the business process and management flow of the packet scheduling command are analyzed, and the necessity of scheduling optimization and the main optimization problems are put forward. Secondly, aiming at the main problems existing in the dispatch and command of luggage and parcel, the functions of the three-level dispatching department are optimized from three aspects: statistical analysis, monitoring and warning, and transportation capacity deployment. On this basis, the system optimization theory is used to optimize the flow of dispatching information transmission, and the preliminary framework of the packet scheduling command information platform is given. Then, aiming at the implementation of direct luggage and parcel shipment, the paper optimizes the selection of direct shipment number and the scheduling adjustment of train loading schedule. Based on the analysis of the factors affecting the adjustment of the loading plan, the optimization model of the scheduling adjustment by train is constructed to solve the problem of taking account of the priority grade of cargo shipment under the premise of the optimization goal of the largest generalized income of the shipment luggage and parcel at the same time. By using lingo12.0 programming to solve the case, the adjustment results of actual loading plan of each station are given. Finally, according to the decision of the dispatch of transshipment, the optimal selection strategy is given. Based on the framework of transshipment decision index system and the idea of fuzzy mathematics, an improved multilevel fuzzy comprehensive evaluation method is put forward to assist decision making, and the scientific nature of this method is verified by the example of large customer package transshipment.
