摘　　要：图形协同编辑一致性关键技术能够解决多个用户对同一图形文档同步进行协同编辑时产生的并发问题,包括操作不同步、执行顺序冲突、意图冲突等。对实时协同设计过程中的一致性问题产生的原因和过程进行深入分析与研究,提出更为完善的解决方案,通过采用图形协同编辑一致性算法保证图形协同编辑操作一致性。实验结果表明,与其它解决方案相比,图形协同编辑一致性算法具有更佳的可行性与高效性。The key technologies of collaborative editing consistency based on graphics can solve the concurrency problem caused by multiple users collaboratively editing the same graphic documents synchronously.Concurrency problems in graphics editing can lead to inconsistencies in operations,conflicting execution orders,conflicting intents,and the like.We make deep analysis and research on the causes and processes of the consistency problems in the real-time collaborative design process,and then propose a more complete solution.By adopting the graphics co-editing consistency algorithm,the apporach ensures the consistency of graphics collaborative editing operations and verifies better feasibility and efficiency of the key technologies of graphics co-editing consistency compared with other solutions.
