中文摘要: 协同特征CAD系统是缩短复杂产品开发周期的重要技术手段,是下一代CAD系统发展的重要方向。在协同设计环境中,多个设计人员并行地发出各种特征操作命令以及Undo/Redo操作。尽管针对协同CAD系统的相关研究很广泛,但是如何检测操作冲突、协调操作意图并最终得到能够融合多用户操作意图的设计结果是协同CAD系统面临的一个挑战。本项目拟探索多用户意愿冲突检测、面向意愿融合的并发方法、错误恢复机制等关键问题。包括设计并行环境下的拓扑元素变化追踪算法和基于拓扑元素追踪结果的意愿冲突自动检测;操作可交换性的意愿冲突消解方法;符合用户意图的Group Undo/Redo机制,并将研究成果集成入原型系统中进行分析和验证。本项目拟突破多用户操作意图融合这一瓶颈,为新计算环境下协同特征CAD系统的实践应用打下理论基础和技术支持。

英文摘要: A collaborative CAD system is an important technique to shorten the lifecyle of complex products development. It is also the trend for the next-generation CAD systems. In a collaborative environment, feature modeling operations and Undo/Redo operations are issued in parallel. Despite the broad-way research on collaborative CAD systems, to detect operation conflicts and reconcile user intention and finally obtain the design result integrating every designer's intention remains a great challenge.The project is to explore solutions for user intention conflict detection, intention-integration oriented concurrency control method and Group Undo/Redo mechanism to preservation user intention. The algorithms proposed will be tested on the prototype we implemented for this project. The project hopes to be an effective solution for user intention intregation. It also lays the theoretical foundations and technical support for the practice application of feature-based collaborative CAD systems in the new computing environment.
