Yamato, A Study on Process Description Method for DFM Using Ontology, Proceedings of the 19th CIRP Design Conference – Competitive Design, Cranfield University, 30-31 March 2009, pp210978-0-9557436-4-1http://hdl.handle.net/1826/3785Organised by: Cranfield UniversityA method to describe process and knowledge based on RDF which is an ontology description language and IDEF0 which is a formal process description format is proposed. Once knowledge of experienced engineers is embedded into the system the knowledge will be lost in the future. A production process is described in a proposed format similar to BOM and the process can be retrieved as a flow diagram to make the engineers to understand the product and process. Proposed method is applied to a simple production process of common sub-assembly of ships for evaluation.enCopyright: Cranfield University 2009Production processDFMOntologyComputer systemConference paper
