The manufacturing industry is increasingly dependent on digital tools, such as CAD, CAE, CAM, product data management (PDM) systems CNC machines to design and manufacture products. Moreover, the movement toward concurrent engineering drives the need for frequent transformation of the product data between different digital tools. In order to realize the articulate link between design and manufacturing and the traceable manufacturing system, it is necessary to realize interoperable digital tools which represent the semantics of information independently of any implementations. Interoperability characterizes the ability of product model data to accurately represent objects in all collaborative engineering environments. Today, all engineering data, such as geometry representation data, tolerance data, etc., are not used throughout product development processes. An interoperability error makes product model data unusable when applying digital tools. If an interoperability error arises in co … More llaborative engineering applications, tracking the error back to its source is expensive (if not impossible) and requires a significant amount of time. Moreover, the quality of data that represent information should be ensured during the product life cycle. In this research, the Digital Semantic Model that fulfills the above requirements was proposed.The digital semantic product model consisted of the quality assurance of the product model data, the semantic modeling for humans (such as designer and worker), understandable and computer readable data, and the functional modeling for supporting the product life cycle. In order to ensure the product model data, the Product Data Quality Checking method for the ISO Standard product model was proposed. In order to support all of the product lifecycle activities, the functional model for each activity was developed based on the related ISO Standard. In order to represent the semantics of the data, the EXPRESS language for data modeling and XML for representing the data, was adopted. Less

制造业越来越依赖数字工具，如 CAD、CAE、CAM、产品数据管理 (PDM) 系统、数控机床来设计和制造产品。此外，并行工程的发展推动了产品数据在不同数字工具之间频繁转换的需求。为了实现设计和制造以及可追溯制造系统之间的明确链接，有必要实现可互操作的数字工具，这些工具能够独立于任何实现来表示信息的语义。互操作性表征了产品模型数据在所有协作工程环境中准确表示对象的能力。如今，所有工程数据，例如几何表示数据、公差数据等，都没有在整个产品开发过程中使用。互操作性错误导致应用数字工具时产品模型数据无法使用。如果协作工程应用程序中出现互操作性错误，则将错误追溯到其源头的成本很高（如果不是不可能的话），并且需要大量时间。此外，在产品生命周期中应确保代表信息的数据的质量。本研究提出了满足上述要求的数字语义模型。数字语义产品模型由产品模型数据的质量保证、人类（如设计师和工人）的语义建模、可理解和计算机可读的数据以及支持产品生命周期的功能建模组成。为了保证产品模型数据的质量，提出了ISO标准产品模型的产品数据质量检查方法。为了支持所有产品生命周期活动，每个活动的功能模型都是根据相关的 ISO 标准开发的。为了表示数据的语义，采用了EXPRESS语言进行数据建模，采用XML表示数据。较少的
