【摘要】：随着技术的变革和进步,现代制造企业正面临着持续多变和越来越激烈的全球性竞争,信息化管理已成为提高企业核心竞争力的重要途径。产品结构数据作为信息化管理的基础数据,贯穿了产品的生命周期和企业的各个职能部门。由于产品结构数据的形式复杂、涉及部门多和数据量庞大,因此如何保证产品结构数据在生命周期中的准确性和一致性已经成为企业成功与否的关键。产品结构在产品生命周期管理(Product Lifecycle Management, PLM)中通常是以物料清单(Bill of Material,BOM)的形式进行管理。然而,现有的PLM技术将产品生命周期中不同阶段的BOM作为独立对象分别处理,容易导致产品生命周期中各阶段BOM间的数据的不一致。因此,本文主要针对产品生命周期各阶段BOM数据的一致性展开研究,通过建立产品生命周期数据联系模型来管理产品结构数据,保证产品生命周期中数据的一致性。第一章介绍了本文的研究背景,相关领域的国内外研究现状,总结了目前研究的一些不足,给出了本文的研究意义,并提出了论文的主要研究内容和总体框架。第二章提出了基于生命周期数据联系模型的产品结构管理原理,主要阐述了产品生命周期中各种不同BOM的区别和联系,同时给出了BOM一致性管理的需求。在此基础上给出了基于生命周期数据联系模型管理产品结构的原理和技术体系。第三章提出了产品生命周期数据联系模型,阐述了产品生命周期中的各种业务对象、数据对象和联系对象,并利用这些不同的对象来描述产品生命周期数据联系模型。第四章提出了基于生命周期数据联系模型的产品结构视图描述、建立和派生方法,并给出了详细的视图建立和派生的操作步骤。第五章是基于生命周期数据联系模型的多视图管理系统的设计与应用,主要阐述了系统的总体设计、数据库设计等,并实现了基于生命周期数据联系模型的多视图管理系统,并以汽车传动轴总成为例进行了验证。第六章是总结与展望,首先对论文进行了总结,提出了本文的主要研究成果,并对未来的研究和工作进行了展望。
[Abstract]:With the change and progress of technology, modern manufacturing enterprises are facing continuous and changeable and increasingly fierce global competition, information management has become an important way to improve the core competitiveness of enterprises. Product structure data, as the basic data of information management, runs through the product life cycle and each functional department of the enterprise. Because the form of product structure data is complex, involving a large number of departments and large amount of data, how to ensure the accuracy and consistency of product structure data in the life cycle has become the key to the success of enterprises. Product structure is usually managed in the form of Bill of Materials (BOM) (Bill of Material,BOM in Product Lifecycle Management (Product Lifecycle Management, PLM). However, the existing PLM technologies treat the BOM of different phases of the product life cycle as independent objects, which can easily lead to the inconsistency of the data between the BOM phases of the product life cycle. Therefore, this paper mainly focuses on the consistency of BOM data in every stage of product life cycle, and manages product structure data by establishing product lifecycle data connection model to ensure the consistency of product life cycle data. The first chapter introduces the research background, domestic and foreign research status, summarizes some shortcomings of the present research, gives the research significance of this paper, and puts forward the main research contents and the overall framework of the paper. In the second chapter, the principle of product structure management based on life cycle data relationship model is proposed, and the difference and connection of different BOM in product lifecycle are mainly discussed. At the same time, the requirements of BOM consistency management are given. On this basis, the principle and technical system of product structure management based on life cycle data association model are presented. In the third chapter, the product lifecycle data association model is proposed, and various business objects, data objects and contact objects in the product life cycle are described, and these different objects are used to describe the product life cycle data association model. In chapter 4, the description, establishment and derivation of product structure view based on life cycle data connection model are presented, and the detailed operation steps of view establishment and derivation are given. The fifth chapter is the design and application of the multi-view management system based on the life-cycle data association model, mainly describes the overall design of the system, the design of the database and so on, and realizes the multi-view management system based on the life-cycle data association model. It is verified by the example of automobile transmission shaft. The sixth chapter is the summary and prospect. Firstly, the thesis is summarized, the main research results are put forward, and the future research and work are prospected.
