Template-basierte Erfassung von Produktanforderungen in einem CAD System

By using more complexity automobile products, the quantities of requirements to the development process are largely placed. The concept of this work aims to minimize the costing and development times, and to increase the quality of products. The efficient reuse of knowledge in the early development phases requires the support of a template based explicit, structured and consistent model. This model is a collection of all requirements, functions, and processes, which are produced by the development or the modification of existing products over the entire product life Cycle. This will be solved by using of Ontology Tool to build a knowledge model. On the base of this knowledge model is a template based, structured, reusable object-oriented 3D product model in CAD system developed to improve the geometrical and semantic characteristics. These two IT systems (Ontology and CAD) are template based. That means, they are based on the same concept, therefore the exchange could between the two IT systems creatable. The two systems support the work with HTML and XML files, which are the base for Web technology. The use of 3D visualization Internet-based documentation, which is based on Ontology and 3d XML, makes the development process easily, simply, fast, up-to-date and global. The concepts in this work have been implemented in Ontoworks and CATIA, which have been used in six different scenarios in the development process of an automobile industry. The positive employing of CATIA and Ontoworks could be shown in the scenarios, furthermore it could be shown that the product quality was increased by the reuse of the template based IT Tools and the domain construction knowledge and the exchangeability between them was made possible.
