Modular architecture model of CSCD system

Hongxue XU, Hong ZHENG, Xiuying GUO

《机械工程前沿（英文）》 2010年第5卷第4期页码 470-475 doi: 10.1007/s11465-010-0119-5

摘要： A modular architecture model of a computer-supported collaborative design (CSCD) system is proposed on the basis of the hierarchical structure characteristics of a distributed collaborative design system and advanced component object technology. The model mainly regards the module as the core organizing and managing design objects and uses the common object request broker architecture (CORBA) specifications as an interactive platform to achieve object communication. The browser/server computing model deals with the remote heterogeneous collaborative design problem. Product design strategies and mechanisms for collaborative design are separated to facilitate the application of distributed collaborative design environment for quick implementation. The open design framework for CSCD system developers can support the implementation of distributed collaborative design to improve product design speed and reduce product development time. The modular CSCD system (MCSCDS) model and its implementation are achieved in the modular CSCD, a prototype system.

The role delegation authorization model of a computer-supported cooperative design system

摘要： According to the specific characteristics of a computer-supported cooperative design (CSCD) system, the characteristics of role delegation authorization (RDA) are analyzed and deduced, and a set of fitful status is arrived at. Because of the diversified characteristics of RDA features in different systems, the RDA model has multi-varying status. On the basis of the basic model of role-based access control (RBAC), some basic characteristics of RDA are summed up. Then, according to the specific characteristics of CSCD system, the characteristics of RDA are recombined to develop a RDA model that is suitable for the CSCD system. It is different from the conventional role authorization models of RBAC, that is, it adopts the decentralized authorization management instead of the centralized one in CSCD system, which makes the management more flexible. This model is verified through a specific case of CSCD system.
