【摘要】：受我國經(jīng)濟(jì)下行壓力的影響和公路、航空等多種運(yùn)輸方式的競爭,我國鐵路貨運(yùn)量雖然保持增長,但是增速正在逐年減緩。為了應(yīng)對壓力和挑戰(zhàn),提高鐵路運(yùn)輸?shù)氖袌龈偁幜?我國鐵路開展了貨運(yùn)組織改革。貨改對傳統(tǒng)鐵路運(yùn)輸組織方法提出了新的要求,因此亟需針對貨改條件下的鐵路運(yùn)輸組織方法優(yōu)化進(jìn)行研究。論文提出了分界口的定義和研究分界口車流組織的重要作用,總結(jié)出了我國鐵路主要分界口的基本信息,分析了我國鐵路局主要分界口交接車作業(yè)量現(xiàn)狀,分析了我國鐵路局間分界口的空車車流流向,分析了菜單調(diào)度命令和迂回調(diào)度命令這兩種總公司常用的車流組織方法。從裝車、卸車、機(jī)車機(jī)班、區(qū)段通過能力限制、編組站作業(yè)、獎勵考核機(jī)制等六個方面分析了影響分界口交接車的主要因素。論文從貨運(yùn)辦理程序、貨運(yùn)計劃編制、貨運(yùn)定價策略、鐵路服務(wù)、市場營銷策略等五個方面分析了進(jìn)行貨運(yùn)組織改革的必要性,歸納了鐵路貨運(yùn)組織改革的基本思路和主要目標(biāo)。從需求受理及實貨核實、貨物運(yùn)輸計劃編制、日常裝車管理與運(yùn)力保障機(jī)制等三個方面對比分析了鐵路貨運(yùn)組織改革和傳統(tǒng)貨運(yùn)組織方法的不同。從車流流向的復(fù)雜性、運(yùn)到時限和客戶個性化需求等三個方面總結(jié)出鐵路貨運(yùn)組織改革對分界口車流組織的影響。論文從鐵路貨運(yùn)的服務(wù)水平和運(yùn)營收益兩個方面定義了分界口交接車效益,從落實貨運(yùn)組織改革-誘導(dǎo)車流產(chǎn)生-制定分界口交接車方案-獲得運(yùn)營效益的基本流程描述了貨改條件下分界口交接車方案優(yōu)化問題,選擇服務(wù)水平變化和運(yùn)營收益變化作為分界口交接車方案的優(yōu)化目標(biāo),分析了模型的約束條件,構(gòu)建了分界口交接車方案優(yōu)化模型,并基于第1、2類別列車在車站和限制區(qū)間對第3類列車通過能力的扣除,設(shè)計了求解模型的算法。論文分析了成都鐵路局和西安鐵路局的廣元分界口和達(dá)州分界口的交接車現(xiàn)狀,針對廣元站和達(dá)州站的通過能力構(gòu)建分界口交接車方案優(yōu)化模型,通過查閱相關(guān)資料確定了模型相關(guān)參數(shù),計算第1、2類貨物列車交接對第3類貨物列車交接的扣除,并運(yùn)用lingo求解軟件進(jìn)行計算,最終得到分界口交接車優(yōu)化方案。論文在總結(jié)鐵路運(yùn)輸調(diào)度一線工作經(jīng)驗和資料文獻(xiàn)分析的基礎(chǔ)上,從強(qiáng)化全路統(tǒng)一調(diào)度指揮、優(yōu)化分界口交接車方案、加強(qiáng)裝卸車組織力度和建立健全應(yīng)急運(yùn)輸組織預(yù)案等四個方面提出鐵路運(yùn)輸分界口車流組織優(yōu)化對策建議。
[Abstract]:Under the influence of the downward pressure of our economy and the competition of many transportation modes such as road and aviation, the railway freight volume of our country keeps increasing, but the growth rate is slowing down year by year. In order to meet the pressure and challenge and improve the market competitiveness of railway transportation, the freight transport organization reform has been carried out in our country. The freight reform has put forward new requirements to the traditional railway transportation organization method, so it is urgent to study the optimization of the railway transportation organization method under the freight reform condition. This paper puts forward the definition of the boundary port and the important role of studying the traffic flow organization of the boundary port, summarizes the basic information of the main railway boundary port of our country, and analyzes the present situation of the traffic volume of the main intersecting intersection in the railway administration of our country. In this paper, the flow direction of empty train flow at the boundary between railway administrations in China is analyzed, and the two common methods of train flow organization are analyzed, such as menu dispatching command and circuitous dispatching command. In this paper, the main factors affecting the acceptance of the vehicle are analyzed from six aspects: loading, unloading, locomotive shift, section passing capacity limitation, marshalling yard operation, and reward assessment mechanism. This paper analyzes the necessity of freight transport organization reform from five aspects: freight handling procedure, freight planning, freight pricing strategy, railway service, marketing strategy, etc. The basic ideas and main objectives of railway freight transport organization reform are summarized. The differences of railway freight organization reform and traditional freight organization methods are compared and analyzed from three aspects: demand acceptance and actual goods verification, cargo transportation plan compilation, daily loading management and transportation capacity guarantee mechanism. This paper summarizes the influence of railway freight organization reform on the traffic flow organization at the boundary port from three aspects: the complexity of the flow direction, the time limit to transport and the customer's individualized demand. In this paper, the benefits of service level and operating income of railway freight are defined. From the basic process of carrying out the reform of freight transportation organization, inducing the production of vehicle flow and formulating the plan of receiving cars by dividing the intersection, this paper describes the optimization problem of the plan of picking up the vehicles for the intersecting port under the condition of cargo reform, and the basic process of obtaining the operational benefits is described. The change of service level and operating income are selected as the optimization objectives of the plan, and the constraint conditions of the model are analyzed, and the optimization model of the plan is constructed. Based on the deduction of the passage capacity of the first class 2 train at the station and the restricted interval, the algorithm of solving the model is designed. The paper analyzes the present situation of the intersections of Chengdu Railway Bureau and Xi'an Railway Bureau, and constructs the optimization model of the intersecting trailers according to the capacity of Guangyuan Station and Dazhou Station. The model parameters are determined by consulting the relevant data, and the deduction of the transfer of the first class 2 cargo train to the third type freight train is calculated. Finally, the optimization scheme of the boundary oral crossover train is obtained by using the software of lingo to solve the problem. On the basis of summing up the working experience and literature analysis of railway transportation dispatching line, this paper strengthens the unified dispatching command of the whole railway line, and optimizes the train-taking scheme of the intersecting port. To strengthen the organization of the loading and unloading vehicle and to establish and perfect the emergency transportation organization plan, the paper puts forward the countermeasures and suggestions for the optimization of the traffic flow organization at the railway transportation boundary crossing.
