Knowledge-based Design — An Integrated Approach

KBE TEMPLATE UPDATE PROPAGATION SUPPORT - Ontology and Algorithm for Update Sequence Computation

“…In addition to knowledge storage, templates are also used to provide standardized parts and assemblies for design activities, and to integrate proven design solutions into future product design processes (Katzenbach et al, 2007). Katzenbach et al (2007) also exposed that the mandatory use of templatebased design processes enhances the design maturity during the complete design phase. Moreover, Kamrani and Vijayan (2006) showed an integrated design approach based on templates technologies that allows to reduce drastically the development time needed for new products.…”

“…In large and complex assemblies like those present in automotive or aerospace industries, the number of templates and template instances can reach several thousands and even more. This implies a huge effort to maintain them as they become more complex by incorporating new potential variants for future design (Katzenbach et al, 2007). There is a second challenge regarding template update, that concerns the propagation of the modifications done to templates.…”

“…The automotive industry has also integrated templates into their development processes. Haasis et al (2007) and Katzenbach et al (2007) presented the template-based process at Daimler AG, an automotive enterprise. There will be a need in the future to standardize component concepts between product families to face the complexity of products and processes.…”

“…It is the largest set of OWL that provides decidable reasoning procedures. Katzenbach et al (2007) pointed out from their study that relations between documents need an efficient visualisation tool to have an overview on all interdependencies. With this ontology, we want to provide a classification and an efficient overview of all explicit and implicit dependencies in templates and assemblies.…”

“…Nowadays, high-end industries such as automotive or aerospace industries are designing products that are more and more complex and that integrate various disciplines. The product diversification and the increase of the model range has motivated new IT tools and has impacted the product development process (Katzenbach et al, 2007). One change during the last years is the democratisation of Knowledge-Based Engineering (KBE) which has become a standard in product development.…”
