【摘要】 PLM作为制造企业信息化的基础管理平台,需要能在企业各种异构的系统环境下支持进行企业管理、产品研发等活动,以求达到企业对市场的快速响应。在现有PLM的应用和实施中,主要存在异构系统环境工作困难或不支持,CAX集成工具的数据共享与交换复杂,系统维护实施困难等问题。因此构建合理的具有可扩展性和可维护性的PLM体系架构成为了PLM研究的重要方向。本文首先对PLM的定义与内涵进行研究,指出其在企业信息化中发挥的作用。然后通过讨论现有PLM系统在企业信息化应用中存在的问题,分析其系统体系架构存在的不足。在SOA的技术特点和框架的基础上,指出使用SOA技术构建PLM系统的优势,重点对实现SOA技术的其中一种方法——Web服务进行深入研究。在分析了企业信息化对PLM系统需求的基础上,建立面向服务的智能客户端PLM系统工作模型和系统访问模型,讨论以接口方式来实现系统的集成,以此来构建面向服务的PLM系统体系框架。通过对客户端形式的研究,将系统体系架构划分为基于智能客户端的多层次体系架构。然后进一步对系统架构中各个层次展开设计和实现,重点对Spring.Net中间件等关键技术进行了详尽的研究。并构建面向服务的PLM系统与其它信息化系统的集成模型,实现了标准化接口的集成方式。最后,本文在PLM系统体系架构方面的研究成果被应用于重庆康明斯发动机有限公司的PLM信息化系统中,取得了显著的经济效益。文中结合CCEC-PLM的工程应用,给出了上述技术的应用实例,进一步验证了本文研究内容的实用性和有效性。更多还原

【Abstract】 As the basic information management platform of manufacture enterprises, PLM should provide functions such as enterprise management, product development and manufacturing in diverse environments in fast response to markets. However, there are many problems in the application and implement of the PLMS nowadays, including hardly worked or not supported in distinct environments, data exchanged hardly with CAX tools, difficult in system upgrade. Consequently design an extensible and maintainable PLM architecture becomes an issue in the PLM research.Firstly, the definition and connotation of PLM is discussed and the significance in enterprise informationization of PLM is also pointed out, and a new PLM architecture is established on the problems exists in the PLMS. The framework characters and advantages of SOA are also researched. Then, one of the implement methods to SOA——WebServices is investigated.Secondly, a work model and system access model of service-oriented PLM system have been put forward. A new services-oriented PLM architecture is established based on the model, and each layer exchange with interfaces.Thirdly, the PLM system is divided into Smartclient based N-tiers architecture after research on the clients. Each tier of architecture is further implemented and the most important technology such as Spring.Net is researched explicitly. Then the model of PLMS integrated with other systems is constructed with standard interfaces.Lastly, the research achievements of this thesis are validated in some cases applied in ChongQing Cummins Engine Company, and the conclusion is drowned followed by anticipations of the research aspects and the trends of PLM.更多还原
