【摘要】 随着计算机和网络技术的不断发展，Internet已经成为人们生产和生活中的不可缺少的组成部分。社会的各个领域都在努力利用现有技术建立网络化的应用体系，进而实现信息交互和资源共享。就现代企业而言，建立一个基于Internet／Intranet的灵活的、易于扩展和维护的企业信息系统，是企业适应瞬息万变的市场环境，促进自身发展壮大的必然选择。基于Web的物流仓储管理系统是通过构建一个面向公众的操作环境，克服了传统物流管理系统功能单一、难以与企业其他业务系统紧密集成的缺点。本课题的研究目标就是提出一个在J2EE平台下，运用MVC设计模式来实现基于Web的物流仓储管理信息系统的解决方案。本文首先分析了物流仓储管理系统应该具备的作用，在此基础上对系统功能进行详细分析，并得出具体的功能模型。然后根据该功能模型设计出基于J2EE平台下的系统结构。J2EE技术提供了开发分布式应用的底层服务支持，同时也提供了一个基于JavaBean、Servlet和JSP等组件开发Web应用的平台。以J2EE的多层体系结构为依据，本文给出了一个四层的设计模型，它包括了客户层、Web层、业务层和数据层，其中的业务层又被划分成业务逻辑层和数据持久化层两个子层。在这个多层设计模型中，Web层负责控制业务流程、动态生成客户端页面等功能；业务逻辑层实现了核心业务逻辑，持久化层负责对数据库的具体操作。本文最后还探讨了基于Web的GIS以及在物流领域的应用，并对求解最短路径问题的几种经典算法及算法的优化进行了研究。更多还原

【Abstract】 With the development of computer and Internet technology, Internet has become an indispensable part in people’s live and production. Each area of our society are trying to establish application system based on network, by using this way to implement the communication of information and the share of resource. As modern enterprises, if they want to adapt the variational environment, establishing a flexible and extensible enterprise information system based on Internet/Intranet is a necessary choice. By building an open environment for the Physical Distribution and Storage Management System, which is based on web technology, overcomes restraints of simplex function and difficultness to integrate with other business system in traditional Physical Distribution and Storage System, establishes a dynamic controllable uniform integrative platform, supplies the advanced solutions of Electronic business for enterprise.The article first analysed the actions of Physical Distribution and Storage Management System, based on this, it analysed the functions in detail and get the material models. Then we designed the system framework based on J2EE platform as the models.J2EE provides the infrastructure of distributed application, which also is an advance platform of developing Web application based on J2EE components, such as JavaBean, Servlet and JSP. According J2EE multi-layer architecture, the model is composed of four layers, which includes client layer, Web layer, logic layer and data persistent layer. Logic layer provides the distributed service and includes business sublayer and persistent sublayer. Business sublayer implements business logic and persistent sublayer is responsible of operating with data source.Finally, this paper discuss the application of GIS based on Web, and reseache some classical algorithms to solve the problem of shortest path, then optimize it.更多还原
