【摘要】 物流作为一种经济活动,随着商品经济发展而形成。在经济日益全球化的今天,现代物流作为“第三个利润源泉”正受日益广泛的重视,并面临着前所未有的发展机遇。物流产业得到了极大的发展,我国物流业也在这股潮流中随着经济的发展和经济体制改革的进一步深化而成为市场经济中一个竞争激烈的行业。随着物流的发展,人们也越来越重视物流管理,通过对物流全过程的有效管理,以期实现降低成本和提高服务水平两个目的。物流管理和信息系统全过程控制是物流管理的核心问题。供应商必须全面、准确、动态地把握散布到全球各个中转仓库、经销商、零售商以及汽车、火车、飞机、轮船等各种运输环节之中的产品流动状况,并以次为根据随时发出调度指令,调整市场策略。如何将网格GIS整合到物流信息管理系统中,将成为现代物流管理的一个重要课题。本论文的具体内容如下:第一章介绍论文的相关研究背景,选题意义以及论文的主要工作及创新点。第二章主要介绍了物流以及物流配送系统的概念、分类、特点以及流程等,分析了GIS的基本概念、特点、应用领域等。在此基础上,提出了基于GIS的动态运输路线的选择研究方法。第三章研究GIS的发展历程以及网格GIS的特点,将网格GIS应用到物流管理中。分析了网格技术的概念、特点、应用领域以及体系结构;并分析了网格GIS的概念、特点以及体系结构。第四章研究了网格计算与空间信息网格技术,改进了基于中间件的网格GIS模型框架的设计,并将该框架用于“数字物流”的概念以及模型中。第五章研究分析了智能代理中间件Agent的基本理论、结构分类、模型的优点以及在网格计算中的应用;将中间件Agent技术改进于“四重地理空间网格”模型框架中,提出了基于Agent的网格资源控制体系结构AGRC。并在此基础上进行实验分析,结果论证了该结构的有效性。最后对本论文所作的工作进行总结,并对后续的研究工作进行展望。更多还原

【Abstract】 Logistics came into being along with the economic development as a kind of economic movement . Nowadays , modern Logistics is attached much importance as a third profit headspring , and in face of an unprecedented developing opportunity . Logistics industry has achieved much more developments , and Logistics in our country has became a dog-eat-dog industry along with the economic development and innovation of economic system . People has though much of the management of Logistics industry and is willing to reduce the cost and improve the level of service .Logistics management and the whole control course of information system is the core problem . The provider must grasp the circulation of products which are distributed to retailers, transferred warehouse, dealers and every transportation taches such as motorcars, trains, airplanes and steamships by rule and line and dynamically . They must attempt and adjust the marketable strategy momentarily in terms of the circulation of products . That how to make the best of Grid GIS into the information management system of Logistics will be a very important theses of modern Logistics .The main work of this paper is shown in detail as follows :Chapter 1 introduces the background , significance ,work and innovation of the paper .Chapter 2 introduces the definition , categories , characters of Logistics distribution system and the basic definition , characters and application fields of GIS. Sets up the study on location of Logistics center and dynamic route selection .Chapter 3 studies the developing course of GIS , take advantage of GIS into Logistics management . Introduces the definition , character , application fields and system framework of Grid and Grid GIS .Chapter 4 sets up the definition of“numeric Logistics”and its framework ; make Agent in use of the architecture model of Quadruple Geo-spatial Grids of Grid GIS . Chapter 5 studies the basic theoretics and the strongpoint of framework of middle-ware Agent . Also , it analyzes the application of Agent in Grid infrastructure and sets up the framework of Agent-based Grid Resource Control. In the end ,we can learn by experiment that the framework is viable .At last ,the paper summarizes the main points that the study tries to achieve and points out the further study in future .更多还原
