In the manufacturing industry, equipment which is the material base of organization produc-tion plays a very important role. Modern device exhibits complicated structure, perfect functions, and high degree of automation. It can effectively improve equipment management by using advanced infor-mation technology. Hence, implementation of an equipment management information system has be-come an important part of enterprise informatization. With the increasing complexity of the architecture and web applications of the equipment management software, the original CGI, ISAPI and other tech-nologies are difficult to meet the requirements to access and operate distributed objects. The best way to manage the risk is to build a distributed object framework of web design. Therefore, in this paper a method of modeling web-based equipment management system (WEMS) with unified modeling lan-guage (UML) was presented. The full life cycle visual modeling of a specific areas system was studied by combining component technology and web technology, aiming to achieve the goal of a reuse system. Finally, a highly reusable WEMS was developed and proved to be effective in the actual project.%设备是企业组织生产的物质基础,在制造业中起着非常重要的作用.现代设备呈现出结构复杂、功能完善、自动化程度高等特点,只有利用先进的信息技术来对其进行管理,才能有效提高设备管理的工作效率.因此,实现设备管理信息化成为了企业信息化的重要组成部分.然而,随着面向设备管理领域软件体系结构和Web应用复杂性越来越高,原有的CGI、ISAPI等技术,已很难满足对分布式对象访问和操作的需求.所以,本文以实现系统的复用为目标,将组件技术与Web技术相结合,在某烟厂的实际项目Web-based Equipment Management System (WEMS)开发过程中,采用统一建模语言(UML)对特定领域设备管理软件进行了从需求模型、静态模型、动态模型到物理模型的软件全生命周期可视化建模,提出了分布式系统建模的解决方案.最终,在Microsoft.NET框架下,采用C#吾言和SQL2000数据库开发了WEMS系统,同时也验证了该分布式系统建模方案的有效性.
