分散环境下基于网络的快速产品开发模式 总被引:5,自引:2,他引:5
分散环境下错综复杂的产品开发流程和大量信息,限制了产品一切速度。但不管开发过程如何复杂,都可以抽象为异步和同步两大类。在此基础上归纳形成了基于网络的产品快速开发的异步同步耦合新模式。异步同步耦合是指异步过程和同步过程相互影响和相互作用,整体完成产品开发的任务。同时解决了分布式异步执行的管理过程的可视化技术和实时监控技术,构建了支持异地协同的集成环境。 相似文献

An asynchronous and synchronous coupling approach in networked rapid product development 总被引:3,自引:1,他引:3

Faced with today's competitive market, the development of innovative product needs to be accelerated. But this is limited by heterogeneous systems and a distributed environment. A way of utilising network technology to this end must be found. In this paper, we use a new approach, called asynchronous and synchronous coupling, which is a network-based product development approach. This is then applied to rapid-response manufacturing by small- and medium-sized enterprises in a distributed environment. It demonstrates integrated thinking, high development speed and a transparent development process. Visual technology and real-time monitoring technology are used to solve asynchronous process and data management problems. An ICE (integrated collaborative environment) is also created to support synchronous collaboration. 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

Retrieval of CAD model data based on Web Services for collaborative product development in a distributed environment 总被引:1,自引:0,他引:1
Byung Chul Kim Duhwan Mun Soonhung Han 《The International Journal of Advanced Manufacturing Technology》2010,50(9-12):1085-1099
Web Services, a distributed component technology based on XML and the Internet, is used for integrating heterogeneous systems under a distributed environment. Since CAD data is used as master data across the lifecycle of a product, it is important to share CAD data efficiently among the systems that are used for collaborative product development in a distributed environment. In this study, the concept of Web Services for CAD (WSC), which provides CAD data when required by organizations participating in the collaborative product development, is introduced. In addition, the technical details of WSC, including the system architecture of WSC, XML-based neutral CAD model, and interface for retrieving CAD model data are discussed. Finally, the implementation of WSC to Pro/ENGINEER and its experimental result are explained. 相似文献
