【摘要】：鐵路大功率機(jī)車檢修基地是我國鐵路技術(shù)裝備現(xiàn)代化的重要項目，主要承擔(dān)大功率機(jī)車的綜合維修任務(wù)，兼?zhèn)渖a(chǎn)制造能力。檢修基地的機(jī)車檢修以生產(chǎn)流水線作為主要檢修方式，全部生產(chǎn)和管理實現(xiàn)信息化，作為生產(chǎn)運行的基礎(chǔ)保障，基地內(nèi)部物流配送系統(tǒng)信息化是整個信息化系統(tǒng)中極其重要的一環(huán)。 隨著經(jīng)濟(jì)的迅速發(fā)展，市場環(huán)境和產(chǎn)業(yè)結(jié)構(gòu)都發(fā)生重大的變化，這種變化需要現(xiàn)代化的物流業(yè)為支撐。但是具體到機(jī)車檢修基地內(nèi)部物流配送的微觀層面，傳統(tǒng)的生產(chǎn)作業(yè)、生產(chǎn)指揮和生產(chǎn)組織方式已經(jīng)很難滿足大功率機(jī)車檢修任務(wù)所提出的物流配送要求，隨著現(xiàn)代化的經(jīng)營、管理技術(shù)的不斷創(chuàng)新，結(jié)合前沿化的計算機(jī)、網(wǎng)絡(luò)、通信等IT技術(shù)日新月異的發(fā)展，物流作業(yè)網(wǎng)絡(luò)化、物流運輸精準(zhǔn)化、物流調(diào)度智能化、物流管理全面化已經(jīng)成為物流產(chǎn)業(yè)發(fā)展基本方向。 傳統(tǒng)的企業(yè)物流系統(tǒng)不能實現(xiàn)對客戶和車輛的可視化管理，沒有針對車輛路徑進(jìn)行動態(tài)仿真，而且業(yè)務(wù)規(guī)劃和配送分析等功能無法達(dá)到令人滿意的效果，尤其在管理和存儲海量數(shù)據(jù)等方面，傳統(tǒng)的配送系統(tǒng)處理效率不高，且操作不夠靈活，這就要求有一種新的物流配送系統(tǒng)的出現(xiàn)，GIS（Geographic Information System）具有良好的空間數(shù)據(jù)管理、檢索、查詢和空間分析等能力，以及卓越的地圖顯示能力。所以考慮將GIS技術(shù)和DGPS（Differential Global Positioning System）技術(shù)應(yīng)用到物流配送系統(tǒng)中來輔助解決路徑規(guī)劃問題。針對目前物流配送系統(tǒng)存在的一系列問題，本文將GIS和DGPS應(yīng)用于物流配送系統(tǒng)中，實現(xiàn)對搬運車輛的實時跟蹤、控制與組織、指揮，包括：搬運車輛作業(yè)狀態(tài)跟蹤、空閑狀態(tài)跟蹤和位置狀態(tài)管理等。同時通過系統(tǒng)軟件控制可實現(xiàn)實時數(shù)據(jù)監(jiān)測、歷史軌跡回放、地圖加載等實用功能，提高了有效的管理途徑。本文針對基于GIS的VRP（Virtual Reality Platform）模型與傳統(tǒng)VRP模型的區(qū)別，建立了考慮運輸路徑的GIS路徑網(wǎng)絡(luò)模型，最后在GIS地理信息系統(tǒng)平臺上設(shè)計并實現(xiàn)了GIS實效物流配送系統(tǒng)。通過與檢修基地庫存管理信息系統(tǒng)連接，實時反饋、傳遞庫存信息，確保搬運作業(yè)的有效性和精準(zhǔn)性。 通過實驗驗證，該GIS實效物流配送系統(tǒng)與傳統(tǒng)物流配送系統(tǒng)相比，大幅度降低了路線總花費，縮短了行車總距離，降低了配送成本。由于在配送前已設(shè)置好了運輸路徑，因此求解的最佳路線都是實時可行的，極大程度上避免了最佳配送方案因運輸路徑擁堵問題無法執(zhí)行的情況發(fā)生，極大的提高了物流企業(yè)的配送效率。 最后，，文章給出了機(jī)車檢修基地內(nèi)部物流配送的基本方案，在創(chuàng)建系統(tǒng)基本框架的基礎(chǔ)上，對系統(tǒng)的硬件、軟件設(shè)計建立了初步的模型。實際系統(tǒng)在鄭州藍(lán)麟機(jī)電技術(shù)有限公司得到了推廣應(yīng)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.
