随着大型图案设计任务的复杂化、设计人员的专业化、设计地理位置的分散化以及计算机网络计算集成化，开发计算机支持的协同图案设计系统成为必要和可能。为了使人们对计算机协同设计系统有所了解，首先阐述了图案设计系统的基本过程，进而分析了计算机支持的多用户协同图案设计的基本要求；然后描述了时间、空间上分散，而在任务上又相互依赖的多个设计者之间的交互方式及协作机制；定义了协同图案设计系统的要素，并在此基础上，构造了多用户协同图案设计系统的逻辑模型；研究了协同编著系统中多用户图案的管理、操作和并发控制模型，同步图案设计的管理模型，控制模型以及消息的管理策略；最后设计了图案设计系统的结构模型。

With the complication of great pattern design, the speciality of designer, the dispersal of design location and the integration of computer networking computing, It is necessary and possible to develop computer supported pattern design system. This paper applies CSCW technology in the field of computer art and construct cooperative pattern design model. It focuses on the cooperative pattern design and analyze modes of the cooperative design, the structure, the relative management and control. Firstly, it presents the basic process of pattern design system, analyzes the basic requirement of computer supported multi user pattern design, describes the interactive mode and cooperative mechanism of multi designer, whose tasks are dispersed in temporal and space, and are dependent on each other. It defines the elements in a cooperative pattern design system and builds up a logical model of pattern design system. It studies not only the pattern management model and concurrent control of multi designers, but also presents design conference management model, the synchronous conference model, message management policies model in a pattern design system. Finally, it gives the structure model of pattern design system.
