In the second chapter , under the characters and requirements of mc - oriented product structure management , a product function module which is based on module technology is presented ; the characters of bom under the basis of mc is analyzed ; bom is divided to assemble - product - bom and function - structure - bom based on the stratum ; the tree structure model is revised and a net structure model is introduced ; the realization of the tree structure is discussed in the end . in the third chapter , the shorts of the available reusing technology of the manufacturing process are analyzed at first 第二章根据大批量定制条件下产品结构管理的要求和特点，提出了基于组件技术的产品功能模块技术；分析了大批量定制条件下bom的特点，按照订单生产和多项目管理的特点，将bom按层次划分为组合产品bom和功能结构bom ；改进和提升了已有的树状结构模型，引入了部分网状模型；最后讨论了大批量定制条件下产品结构树的实现和产品结构的后续增补。
The third , fourth and fifth chapters mainly explore the technological process , framework , and assessment of corporate knowledge management , and by use of the technological process of corporate knowledge management as the main thread , to discuss the basic framework of corporate knowledge management from five aspects : human capital management , organization structure management , information technology management , corporate culture construction , and cooperative network management . finally , the goals , principles and method of assessment of corporate knowledge management are proposed and an assessment index system of corporate knowledge management is established 第三章到第五章着重研究了企业知识管理的流程、构架和评估等内容，以企业知识管理的流程为主线，从人力资本管理、组织结构管理、信息技术管理、企业文化营造、合作网络管理等五个方面论述了企业知识管理的基本构架，提出了企业知识管理评估的目标、原则和方法，建立了企业知识管理的评估指标体系。
At the base of theory research on the project , authors make a prototype system of pdm , and select the machine tool building industry having complicated pdm to practise , have developed the pdm having many fuctions included that product structure management , version management , product configuration management , product bom management , coding management , system management 在课题理论研究的基础上,构架了pdm原型系统,并选择了产品数据管理较为复杂的机床制造行业进行实践,开发出了包含:产品结构管理、版本管理、产品配置管理、产品bom管理、编码管理、系统管理的产品数据管理系统。
This format is independent of any actual computer system , can be used to various application and system , in order to keep the integrity and continuity of the product data when they are exchanged between different systems , we referenced the basic contents of product description in step standard , established product structure modle and guranttee the correctness and shareness of the information in product structure managing system ; at the same time , built the foundation for later expanding of the system functions . starting from the previous analysis , we make the function that the software will achieve very clear . we have explained briefly the relations between every system module and their accomplishing principles of the every funetion and the finish the initial design of the software 为了产品数据在不同的系统之间进行交换时保证其完整性和连续性，充分参考了step标准有关产品描述( iso - 10303 - 44中的产品结构模式和iso - 10303 - 41中的产品定义模式)的基本内容，建立了产品结构模型；保证了产品结构管理系统的信息的正确性和共享性；同时也为以后系统的功能的扩展奠定了基础。又从前面的分析出发，明确了软件实现的功能。对各系统模块之间的数据联系及其各自实现的功能实现原理进行了简要说明，完成了软件的总体设计。
Secondly the thesis centers around this product structure information integration model and works further over product structure definition and configuration management in pdm . theory and method of this management portion are discussed respectively with production structure management , configuration management and assembly - powered tiered process management and are applied to describe the implementation process of product structure definition and configuration management . the transforming mode from designing to manufacturing stage in product structure definition and configuration management is also dissertated 然后围绕产品结构信息集成模型，深入研究了pdm中的产品结构定义和配置管理，从产品结构管理、配置管理和装配驱动的分层式过程管理三个方面来探讨其中的原理和方法，并应用这些管理原理和方法来描述产品结构定义和配置管理的实现过程；同时阐述了在设计阶段向制造阶段延伸时，产品结构定义和配置管理的转换方式。
4 . analyze the configuration management method that used to resolve the phenomenon that the same aircraft model has multi - delivery states caused by customer ' s diversification requirement . from many aspect , such as assign production process task , simplify configuration , setup single product resource database , configuration database , product structure management and validity inspect etc , discuss the capp technique that is fit for configuration management 针对目前因客户需求的多样化而产生的同种机型、多种交付状态现象，分析了为解决这种现象所采用的构型管理方法，从生产过程作业流的划分、简化构型、建立单一产品数据源库、构型库、产品结构管理和有效性检查等多方面，探讨了适合于构型管理的capp技术。
At last , according to the characteristic of report generator in tribon , we established the product structure managing system , studied the algorithm for the generation of the product structure tree and generated the visual product structure tree , and have an eye on the management of bom , taking accout of the correctness of the information of bom , we adopted the method of from top to bottom or from bottom to top to provide information ; and designed 6 bom to accomplish the function 最后，根据tribon系统中报表生成器的特点，建立了产品结构管理系统，研究了产品结构树生成的算法，生成了可视化产品结构树。并对产品物料清单bom的管理进行了研究，考虑到bom信息的准确性，采用了bom以自顶向下分解的形式或是以自底向上跟踪的形式提供信息；并设计了物料清单bom的六种形式来实现其功能。
By analysis the requirement of computer supported cooperative design ( cscd ) , the relative system structure was designed and the model of pscm was built . in this thesis , decision table was used and the module of product structure management and product configuration management had been realized 通过分析协同设计平台对产品数据管理的需求,设计出支持协同设计的产品数据管理系统的体系结构,通过构建产品结构和配置管理模型,采用基于决策表技术的变量配置方法,开发了比较完整的产品结构管理模块、产品配置管理模块,实现了产品结构管理功能与产品变量配置管理功能。
