many engineered products, one of the most critical business processes is managing product data over the entire product life cycle. The design information captured by heterogeneous software systems in proprietary data structures makes it difficult to index, search, refine, reuse, distribute and browse design artifacts across different organizational information systems. In this research, simple yet innovative methodologies are developed to (1) capture and reorganize component design information as a graph model in a Networked Bill of Material (NBOM) to facilitate both linguistic and parametric design information management for a family of products, (2) represent and store design information using ontologies that promote sharing and reuse of components for integrated platform-based product development across various phases of product design, and (3) perform product family analysis of the set of products based on linguistic and/or parametric information.
