基于GIS的物流信息系统的设计与实现.doc

摘 要 近年来，物流作为“第三方利润源泉”受到国内各个行业的极大重视并得到了充分发展。随着信息技术的发展，如何将现代技术应用于物流管理中，使物流管理进入智能化是研究的一个热点。针对我国第三方物流行业的实际情况，本文将研究运用现代优化方法和先进的信息技术(地理信息系统)来解决物流中心选址、最佳配送路线、物流中心服务区优化问题，以提高物流管理运行效率。 论文首先简要介绍了物流管理、GIS、设施选址等相关概念。然后介绍了基于C#的ArcEngine二次开发的方法。又根据选址原则，实际道路交通的特殊性，建立交通网络模型。在此基础上，分析了经典的最短路径算法——迪杰斯特拉(Dijkstra)算法、缓冲区算法和叠置分析算法。同时，本文提出物流中心选址问题，建立中心选址问题模型，得出最终的选址方案，然后又提出最佳路线选择、物流中心服务区优化和最佳物流中心选择的解决方案。最后，在广泛、深入地了解第三方物流企业的标准管理流程的基础上，实现Dijkstra算法，建立了物流GIS研究平台系统，从根本上满足第三方物流企业日常管理的要求。 本文研究的基于缓冲区算法、叠置分析算法的物流中心选址问题和基于网路分析的路径问题都取得了满意的结果，对以后物流管理进入智能化在理论和实际应用上都有一定的参考价值。 关键词：物流GIS 物流中心选址 最短路径 缓冲区分析 叠加分析 ABSTRACT In recent years, logistics as a third-party source of profit by the great attention among various industries and has been greatly developed. With the development of information technology, how to apply modern technology, logistics management, to logistics management into the intelligence is a research hotspot. In view of the actual situation of third-party logistics industry, this article will examine the use of modern optimization methods and advanced information technology (geographic information system) to solve the logistics center location, the best delivery routes, logistics optimization center service area in order to improve logistics management efficiency. Paper briefly introduces logistics management, GIS, facility location and other related concepts. Then introduced based on C #, ArcEngine secondary development approach. Also according to the principle of site selection, the particularity of the actual road traffic, a transport network model. On this basis, analysis of the classical shortest path algorithm - Dijkstra algorithm, buffer algorithm, and overlay analysis algorithm. Meanwhile, the logistics center location problem is proposed to establish center location problem model, that the final location of the program, and then propose the best route selection, optimization of logistics service area and the best choice logistics solutions. Finally, in-depth and extensive und
