Abstract
For OKP companies, how to better manage and record previous product development (PD) knowledge has become a core issue to address in order to improve the PD process, cut down development cost and reduce lead time. In recent years, considerable effort has been placed on developing new enabling technologies for OKP companies to achieve high quality and productivity, and to quickly respond to the changing market to meet customer requirements. Product modelling is a pivotal activity in the PD process. Well-defined product models organise product data, production information and knowledge to satisfy the requirements of rapid changes in the PD environment. In this chapter, a comprehensive review is carried out of recent developments in product modelling technology. Four types of product modelling methodologies are discussed in detail. Two object-oriented product modelling methods, including STEP-based product modelling and UML-based product modelling are reviewed and compared. The research gaps and issues are identified. A generic product modelling framework is proposed to implement product modelling into the current integrated manufacturing environment. Future research trends in product modelling are also discussed.
