About seal research and development system application. First, we analyze the R&D process of scanner product development. Second, we develop R&D ontology, define the knowledge flow and the interaction between R&D and KM process. Third, we build the conceptual model, define the issues, specified functional requirements of the model. Forth, we use the tool to build the system and make primary examinations and evaluations. Finally, we present the unique features, functions, potential benefits, limitations and possible extensions of the model.
