【摘要】：铁路大功率机车检修基地是我国铁路技术装备现代化的重要项目，主要承担大功率机车的综合维修任务，兼备生产制造能力。检修基地的机车检修以生产流水线作为主要检修方式，全部生产和管理实现信息化，作为生产运行的基础保障，基地内部物流配送系统信息化是整个信息化系统中极其重要的一环。随着经济的迅速发展，市场环境和产业结构都发生重大的变化，这种变化需要现代化的物流业为支撑。但是具体到机车检修基地内部物流配送的微观层面，传统的生产作业、生产指挥和生产组织方式已经很难满足大功率机车检修任务所提出的物流配送要求，随着现代化的经营、管理技术的不断创新，结合前沿化的计算机、网络、通信等IT技术日新月异的发展，物流作业网络化、物流运输精准化、物流调度智能化、物流管理全面化已经成为物流产业发展基本方向。传统的企业物流系统不能实现对客户和车辆的可视化管理，没有针对车辆路径进行动态仿真，而且业务规划和配送分析等功能无法达到令人满意的效果，尤其在管理和存储海量数据等方面，传统的配送系统处理效率不高，且操作不够灵活，这就要求有一种新的物流配送系统的出现，GIS（Geographic Information System）具有良好的空间数据管理、检索、查询和空间分析等能力，以及卓越的地图显示能力。所以考虑将GIS技术和DGPS（Differential Global Positioning System）技术应用到物流配送系统中来辅助解决路径规划问题。针对目前物流配送系统存在的一系列问题，本文将GIS和DGPS应用于物流配送系统中，实现对搬运车辆的实时跟踪、控制与组织、指挥，包括：搬运车辆作业状态跟踪、空闲状态跟踪和位置状态管理等。同时通过系统软件控制可实现实时数据监测、历史轨迹回放、地图加载等实用功能，提高了有效的管理途径。本文针对基于GIS的VRP（Virtual Reality Platform）模型与传统VRP模型的区别，建立了考虑运输路径的GIS路径网络模型，最后在GIS地理信息系统平台上设计并实现了GIS实效物流配送系统。通过与检修基地库存管理信息系统连接，实时反馈、传递库存信息，确保搬运作业的有效性和精准性。通过实验验证，该GIS实效物流配送系统与传统物流配送系统相比，大幅度降低了路线总花费，缩短了行车总距离，降低了配送成本。由于在配送前已设置好了运输路径，因此求解的最佳路线都是实时可行的，极大程度上避免了最佳配送方案因运输路径拥堵问题无法执行的情况发生，极大的提高了物流企业的配送效率。最后，，文章给出了机车检修基地内部物流配送的基本方案，在创建系统基本框架的基础上，对系统的硬件、软件设计建立了初步的模型。实际系统在郑州蓝麟机电技术有限公司得到了推广应用。
[Abstract]:The maintenance base of railway high-power locomotive is an important project of the modernization of railway technical equipment in our country. It mainly undertakes the comprehensive maintenance task of high-power locomotive and has the production and manufacturing capability. The locomotive overhaul in the maintenance base takes the production line as the main maintenance mode, and all production and management realize information, which is the basic guarantee for production and operation. The informationization of logistics distribution system is an extremely important part of the whole information system. With the rapid development of economy, great changes have taken place in market environment and industrial structure, which need the support of modern logistics industry. However, on the micro level of logistics distribution in locomotive maintenance base, the traditional production operation, production command and production organization have been difficult to meet the requirements of logistics distribution put forward by high-power locomotive maintenance task. With the modern management, The continuous innovation of management technology, combined with the rapid development of IT technology such as computer, network, communication and so on, the network of logistics operation, the precision of logistics transportation, the intelligence of logistics scheduling, etc. Comprehensive logistics management has become the basic direction of logistics industry development. The traditional enterprise logistics system can not realize the visual management of the customer and the vehicle, does not carry on the dynamic simulation to the vehicle path, and the function such as the business planning and the distribution analysis cannot achieve the satisfactory effect. Especially in the management and storage of massive data, the traditional distribution system is not efficient and not flexible enough, which requires a new logistics distribution system to have a good spatial data management and retrieval. Query and spatial analysis capabilities, as well as excellent map display capabilities. Therefore, the application of GIS technology and DGPS (Differential Global Positioning System) technology to logistics distribution system is considered to help solve the path planning problem. Aiming at a series of problems existing in the current logistics distribution system, this paper applies GIS and DGPS to the logistics distribution system to realize the real-time tracking, control and organization of the moving vehicles, including the operation status tracking of the moving vehicles. Idle state tracking and position state management, etc. At the same time, real-time data monitoring, historical track playback, map loading and other practical functions can be realized by the system software control, which improves the effective management approach. Aiming at the difference between the VRP (Virtual Reality Platform) model based on GIS and the traditional VRP model, this paper establishes the GIS path network model considering the transportation path, and finally designs and implements the GIS effective logistics distribution system on the GIS GIS platform. By connecting with inventory management information system, real-time feedback, transfer inventory information to ensure the effectiveness and accuracy of handling operations. The experimental results show that compared with the traditional logistics distribution system, the GIS has greatly reduced the total cost of the route, shortened the total distance and reduced the cost of distribution. Because the transportation path has been set up before delivery, the optimal route is real-time and feasible, which greatly avoids the situation that the best distribution scheme can not be carried out because of the congestion of the transportation path. Greatly improve the distribution efficiency of logistics enterprises. Finally, the paper gives the basic scheme of internal logistics distribution in locomotive maintenance base, and establishes a preliminary model of hardware and software design of the system on the basis of establishing the basic framework of the system. The actual system has been popularized and applied in Zhengzhou Lanlin Electromechanical Technology Co., Ltd.
