分布式协同设计是支持并行工程的一项重要研究内容。Internet/Intranet的迅速发展为实现分布式协同设计建立了通讯基础。文章首先分析了分布式协同设计的特点和技术要素，在此基础上着重介绍了提出的分布式智能协同设计环境DesignerWeb的框架结构，DesignerWeb中引入了自治体（Agent）和黑板（Blackboard）机制，建立了一种分层的多自治体系统（MultiAgentSystem－MAS）结构。
Distributed Collaborative Design is an important research project supporting concurrent engineering. The rapid development of Internet / Intranet has established the communication foundation for realizing distributed collaborative design. The article first analyzes the characteristics and technical elements of distributed collaborative design, and then introduces the framework of DesignerWeb which is a distributed distributed collaborative design environment. DesignerWeb introduces the mechanism of Agent and Blackboard, A hierarchical Multi-Agent System-MAS architecture.
