Abstract: There are several stages during the course of R&D for complicated products, and different stage requires different document management system. However the traditional collaborative document management system has ignored this aspect. In order to deal with this problem, the concept of library was introduced as the basic logic unit for storage and management of document data corresponding to the phases. Also, a library transfer model based on workflow was presented to implement the automatic document transfer among libraries and the cross-domain collaborative design of document was realized. The logic and physical distributed data storage scheme was designed based on the concepts of project and library, which could meet the requirements of mass data storage and safe management & control of different product design stages. The proposed method could be applied in R&D of document management system for complicated products collaborative design.

Key words: library, workflow, collaborative design, change management
