Concurrent Engineering (CE) is a popular method employed in product development. It treats the whole product design process
by the consideration of product quality, cost, rate of progress, and demands of customers. The development of computer and
network technologies provides a strong support to the realization of CE in practice. Aiming at the characteristics of CE and
network collaborative design, this paper built network collaborative design system frame. Through the analysis of the network
collaborative design modes based on CE, this paper provided a novel network collaborative design integration model. This model
can integrate the product design information, design process, and knowledge. Intelligent collaboration was considered in the
proposed model. The study showed that the proposed model considered main factors such as information, knowledge, and design
process in collaborative design. It has potential application in CE fields. 相似文献

The rapid expansion of enterprises makes product collaborative design (PCD) a critical issue under the distributed heterogeneous environment, but as the collaborative task of large-scale network becomes more complicated, neither unified task decomposition and allocation methodology nor Agent-based network management platform can satisfy the increasing demands. In this paper, to meet requirements of PCD for distributed product development, a collaborative design mechanism based on the thought of modularity and the Agent technology is presented. First, the top-down 4-tier process model based on task-oriented modular and Agent is constructed for PCD after analyzing the mapping relationships between requirements and functions in the collaborative design. Second, on basis of sub-task decomposition for PCD based on a mixed method, the mathematic model of task-oriented modular based on multi-objective optimization is established to maximize the module cohesion degree and minimize the module coupling degree, while considering the module executable degree as a restriction. The mathematic model is optimized and simulated by the modified PSO, and the decomposed modules are obtained. Finally, the Agent structure model for collaborative design is put forward, and the optimism matching Agents are selected by using similarity algorithm to implement different task-modules by the integrated reasoning and decision-making mechanism with the behavioral model of collaborative design Agents. With the results of experimental studies for automobile collaborative design, the feasibility and efficiency of this methodology of task-oriented modular and Agent-based collaborative design in the distributed heterogeneous environment are verified. On this basis, an integrative automobile collaborative R&D platform is developed. This research provides an effective platform for automobile manufacturing enterprises to achieve PCD, and helps to promote product numeralization collaborative R&D and management development. 相似文献
