针对网络化制造模式下协同产品配置设计的信息需求,探讨了一种基于语义网的协同产品配置模型。在该模型中提出了一种基于语义网的协同产品配置模型的体系结构,构建了基于语义网的协同产品配置设计过程模型。通过定义协同产品配置信息的语义元数据描述模型来构建统一的协同产品配置本体,并对散布于网络上的协同产品配置资源进行语义标注,使网络化制造环境下协同产品开发企业之间能够共享产品配置信息,提高分布式协同产品配置设计的信息交互效率以及协同产品开发水平。将该模型应用于某网络化协同设计平台,对模型的有效性进行了验证。 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

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

In distributed product development, Web-enabled collaborative design system with virtual reality (VR) function is good for
representing the design features of 3D product entities in design communication. However, it is too expensive and complicated
for most small and medium-sized enterprises (SMEs) to implement it. This paper explains that the series of still images, which
also present the same efficiency in representing the design features of 3D product entities, can be easily produced at low
cost and require less Internet bandwidth. In order to certify the weaknesses of the remote collaborative design system (RCDS)
for the SMEs, this research started with a preliminary study to identify the unsatisfied problems associated with the mutual
understanding between multi-disciplinary product development team members when using RCDS. Further investigation was presented
as the perception/recognition ability experiment, which was conducted to use three types of 3D product entities representation,
namely the group of still images, image-based VR and model-based VR, to certify the efficient product data visualization for
remote design communication. This research concludes that the proposed representation mode and results of the research would
be helpful for SMEs, which are relatively resource-restrictive, to handle the issues of remote design communication well. 相似文献
