Abstract: The aim of the present paper is to shortly review the problem field the companies are facing as the information should flow between different design support systems and introduce an approach to solve some of the arising problems. The CoreOntology forms the information structure for the Knowledge Base (KB) and standardizes the communication interface for the design support systems. In the present paper, an approach is proposed to share platform independent product, process and system related knowledge between the different design support systems through the KB.

Key-Words: simulation, design support systems, ontology, knowledge management, knowledge-intensive models
