Treffer: Applying object-oriented database technologies in concurrent design processes.

A concurrent design can be used to improve productivity and quality by means of shortening product development time and sharing design information. In order to share information among designers, an object-oriented database management system, which has shown promising capabilities in engineering data processing, is used as a foundation for building a concurrent design architecture in this research. The architecture allows multiple designers to work on the design concurrently, store multiple versions of the design, integrate design information, and evolve the design structure. A procedure of plastic filling injection moulding is used to demonstrate the process of concurrent design, and is compared with the process of C-MOLD, a simulation analysis software package for plastic injection moulding, to show the superiority of the proposed concurrent design architecture.
