摘要：To develop the future CAD systems with concurrent engineering functions, a new CAD model, called Concurrent Engineering-oriented Design Database Representation Model (CE-DDRM), is introduced in this research for supporting various lifecycle aspects in concurrent design. In this model, concepts and behaviors of different design database modeling components, including entities, properties, relationships, tasks, and specifications, are defined at meta-class level. Design database is modeled at two different levels, class level and instance level, representing generic design libraries and special design cases, respectively.
