【摘要】：伴随着2013年习近平主席提出“一带一路”的战略构想,铁路国际联运迎来了重要的发展机遇期。丝绸之路经济带建设不仅为铁路国际联运提供了坚实的基础设施保障,也为其提供了有力的政策支持。口岸站是国际铁路联运过程中的重要节点,是我国在丝绸之路经济带的重要门户。其主要承担国际旅客列车的交接作业、进出口货物列车的运输组织作业,以及进口货物的换装作业。随着“一带一路”各项政策的逐步实施,国际间物流需求在稳步提高,口岸站的进出口贸易额也迅速增长,由此引发的口岸站的换装作业任务也日趋繁重,因此换装能力对于国际铁路联运的顺利开展至关重要。本文对我国的铁路口岸站进行了简要概述,重点总结了铁路口岸站的作业和设备以及口岸站的通关模式,根据铁路轨距和通关模式的不同,将铁路口岸站划分为“一地两检”不办理换装作业的口岸站、“一地两检”办理换装作业的口岸站、“两地两检”办理换装作业的口岸站。通过分析不同类型口岸站的作业流程,并结合现有口岸站站场布局的设计思想,归纳出不同类型口岸站的站场布置图型,为新建口岸站的站场布局设计提供参考。本文将铁路口岸站换装系统看作是三级串联的排队系统,分析了排队系统的构成,通过分析换装系统服务时间的不均衡性以及车站作业的干扰对换装系统能力的影响,建立了口岸站换装系统的三级排队模型。本文对换装系统内到达和出发列车的累计量以及各节点列车累计量与时间分布关系分析的基础上,以换装系统的能力最大作为约束,建立了各节点队列长度均衡模型,求解各节点设备的合理配置数量。提出了闭环排队网络系统中,输入流稳定,各环节配置合理的设备数量,对系统内的作业进行优化,提高作业之间的协调性,系统的车流可达到稳定状态,进而实现换装系统能力最大化。在优化换装线的使用中引入时间片的概念,构建了换装线运用优化模型,并提出了把换装线运用问题转化为构造图的求解问题。最后,本文以阿拉山口站为例,介绍了车站的站场布局,对宽轨进口货物列车的作业流程进行了详细分析,并根据阿拉山口站细确定了各项作业的时间标准,计算了换装系统的既有能力和流程优化后的能力,以及优化后设备的合理配置数量。
[Abstract]:With President Xi Jinping's strategy of "Belt and Road" put forward in 2013, international railway transport has ushered in an important period of development opportunities. The construction of Silk Road Economic Belt not only provides a solid infrastructure guarantee for international railway transport, but also provides a strong policy support for it. Port station is an important node in the process of international railway transport and an important gateway of our country in the Silk Road economic belt. It is mainly responsible for the transfer of international passenger trains, the transport organization of import and export freight trains, and the transfer of imported goods. With the gradual implementation of the policies of Belt and Road, the demand for international logistics is steadily increasing, and the volume of import and export trade of port stations is also increasing rapidly. As a result, the task of changing loading at port stations is becoming increasingly heavy. Therefore, the transfer capacity is very important for the smooth development of international railway transport. In this paper, the railway port stations in China are briefly summarized, with emphasis on the operation and equipment of railway port stations and customs clearance modes of port stations, according to the different railway gauge and customs clearance modes. The railway port station is divided into "co-location" port station, "two places" port station for changing operation, "two places" port station for changing operation. By analyzing the operation flow of different types of port stations and combining with the design ideas of the existing port stations' yard layout, this paper summarizes the layout patterns of different types of port stations, and provides a reference for the layout design of new port stations. In this paper, the railway port station transfer system is regarded as a three-stage series queuing system. The composition of the queuing system is analyzed. By analyzing the imbalance of the service time of the system and the influence of the interference of the station operation on the capacity of the system. A three-level queuing model of port station transfer system is established. Based on the analysis of the accumulative quantity of arrival and departure train and the relationship between the accumulative quantity of each node train and the time distribution, the equilibrium model of queue length of each node is established with the maximum capacity of the system as the constraint. Solve the reasonable configuration of each node equipment. In the closed loop queueing network system, the input flow is stable, the number of equipments in each link is reasonable, the operation in the system is optimized and the coordination between the jobs is improved, the traffic flow of the system can reach the stable state. Furthermore, the capacity of the replacement system is maximized. In this paper, the concept of time slice is introduced into the use of the optimized transfer line, and the optimal model of the operation of the changing line is constructed, and the problem of how to use the changing line into the solution of the structural diagram is put forward. Finally, taking Alashankou station as an example, this paper introduces the layout of station yard, analyzes the operation flow of wide rail imported freight train in detail, and determines the time standard of each operation according to Alashankou station. The existing capacity of the system and the capacity after flow optimization, as well as the reasonable configuration of the equipment after optimization are calculated.
