摘　　要：实时协同设计是CSCW应用的重要领域。实时协同设计过程实际上就是并发冲突产生和消解的过程。本文描述协同图形编辑系统中多对象之间的冲突相关定义,提出一种判别并发操作冲突的关联对象冲突检测策略,设计实现相应的冲突检测算法,最后对算法的可行性进行分析。Real collaborative design system is an important field in the Computer Supported Cooperative Work （CSCW）. The essence of the collaborative design system is to handle and avoid conflicts. In this paper, the definitions of the conflicts among multiple objects in collaborative graphic editing systems are presented, and a conflict detection strategy of multiple related objects used to judge the conflicts among concurrent operations and the related algorithms is proposed. Finally, the availability of the conflict detection algorithm is analyzed.
