Abstract: In order to enhance design roles collaboration in project drawing design systems,according to the design collaboration requirements under computer network environment,a collaborative design system based on instant message was put forward,which combining the knowledge of Agent and workflow and synthesizing route,rule and role in the design process. The implementation method of system was analyzed. The method of controlling the exchanges of critical procedures by using instant message and e-mail monitoring technology on Intranet was provided. In this way,the collaboration of various system roles has been improved to guarantee efficient operation of the project drawing design workflow.

Key words: computer supported collaborative work, workflow, instant message, Agent

摘要： 针对工程图纸设计系统中各角色之间协作性弱的实际问题，根据计算机网络环境下协同设计的需求，结合代理和工作流技术，综合图纸设计业务流程中路由、规则和角色等因素，提出了一个基于即时消息的协同设计系统，分析了系统实现方式，给出了如何在Intranet下引用即时消息和邮件监测等技术来控制设计过程中关键环节的流转，从而提高了系统中各角色间的协作性，保证了工程图纸设计流程的高效运行。
