A DSM-Based Multiple-Domain Modeling of Product Information

Knowledge cannot be promptly shared is the main problem in current ship design processes. Knowledge sharing depended on complete expression of the product information. Therefore, the project management tool—design structure matrix was applied in ship design. Three domains of design structure matrixes including products, tasks and people were built; three domain mapping matrixes which contain each two of the three fields were built too; finally the multiple-domain matrix including these three domains were built. The models established the theory basis for the development of collaborative design prototype system.
