【摘要】：随着计算机技术、网络技术和数据库技术的快速发展,其已经在各个领域得到了广泛的普及和应用,尤其生产控制管理过程中,已经开发和实现了许多的自动化管理系统,有效地提高了生产工作效率,取得了较好的效果。首先,本文详细的描述了产品生命周期管理(PLM)系统的背景,阐述了系统研究的目的与意义,分析了系统国内外研究现状,总结了系统存在的不足及发展趋势,并且归纳了本文的主要研究内容和组织结构。其次,本文分析了系统设计和实现的关键技术,描述了C/S(客户机/服务器)体系架构、B/S(浏览器/服务器)体系架构及其优势、ASP.NET技术、ADO.NET技术、数据库技术和Web服务器技术,为系统设计和实现打下坚实的理论基础。接着,本文从经济可行性、技术可行性、社会可行性和管理可行性等四个方面进行了可行性分析,验证系统开发和实现是可行的;使用UML(统一建模语言)用例对系统逻辑业务进行分析,导出了系统的逻辑业务功能模块,分别是产品结构管理、产品设计文档管理系统、零部件管理模块、产品设计变更管理模块、工作流管理模块、项目管理模块、产品配置管理模块、产品工艺管理模块、工艺电子图板设计模块、数据集成与接口管理模块、可视化与浏览管理模块、系统管理工具模块等十二个关键系统;从易用性、可靠性、安全性等方面对系统进行了性能分析。再次,本文详细的介绍了系统设计原则,给出了系统的网络拓扑结构、软硬件平台、功能层次架构和部署架构等总体方案,同时使用结构化流程图对系统的每一个功能进行了建模和设计,导出了系统逻辑业务结构化流程,同时使用E-R(实体-关系)图和关系表设计了系统数据库。最后,本文使用ASP.NET技术、ADO.NET技术和工作流技术等实现了一个功能完善的PLM系统,给出了系统的运行截图及核心代码,对系统进行了测试,测试结果表明系统具有良好的可用性、可靠性。系统经过部署使用,有效提高了产品设计、产品生产的管理质量,能够实时的控制产品的项目管理,保证施工进度。
[Abstract]:With the rapid development of computer technology, network technology and database technology, it has been widely used in various fields. Especially in the process of production control management, many automatic management systems have been developed and implemented. The efficiency of production has been improved effectively and good results have been obtained. First of all, this paper describes the background of product lifecycle management (PLM) system, describes the purpose and significance of the system research, analyzes the current research situation of the system at home and abroad, summarizes the shortcomings and development trends of the system. And summarized the main research content and organizational structure of this paper. Secondly, this paper analyzes the key technologies of system design and implementation, describes the C / S (client / Server) architecture and its advantages: ASP. Net technology, database technology and Web server technology. Lay a solid theoretical foundation for system design and implementation. Then, this paper analyzes the feasibility of the system from four aspects: economic feasibility, technical feasibility, social feasibility and management feasibility, and verifies that the development and implementation of the system is feasible; Using UML (Unified Modeling language) use case to analyze the logic business of the system, the logical business function modules of the system are derived, which are the product structure management, the product design document management system, the parts management module, respectively. Product design change management module, workflow management module, project management module, product configuration management module, product process management module, process electronic drawing board design module, data integration and interface management module, Twelve key systems, such as visualization and browsing management module and system management tool module, are analyzed from the aspects of usability, reliability and security. Thirdly, this paper introduces the system design principles in detail, and gives the overall scheme of network topology, hardware and software platform, functional hierarchy architecture and deployment architecture of the system. At the same time, each function of the system is modeled and designed by using the structured flow chart, and the structured process of the system logic business is derived, and the database of the system is designed by using the E-R diagram and the relational table. Finally, this paper uses ASP.NET technology, ADO. Net technology and workflow technology to realize a perfect PLM system. The running screenshots and core codes of the system are given, and the system is tested. The test results show that the system has good usability. Reliability. After deployment, the system can effectively improve the quality of product design and product production management, can control the project management in real time, and ensure the construction progress.
