3D Engineering Model Retrieval Based on Enhanced Shape Distributions

To reuse and share the valuable knowledge embedded in repositories of engineering models for accelerating the design process, improving product quality, and reducing costs, it is crucial to devise search engines capable of matching 3D models efficiently and effectively. In this paper, an enhanced shape distributions-based technique of using geometrical and topological information to search 3D engineering models represented by polygonal meshes was presented. A simplification method of polygonal meshes was us...     

基于多Agent的技术准备集成系统

为了实现技术准备过程的集成与协同,将多代理技术和模糊综合评判技术引入到技术准备过程中来.在分析系统业务过程的基础上,建立了基于多Agent的技术准备集成系统框架,该框架由管理Agent、功能Agent和信息Agent构成;提出了由功能适配器、工作引擎、知识库和外部接口构成的Agent模型,并设计了各Agent的内部功能结构,为了解决Agent之间的协同问题,给出了Agent之间的协作模型,并在研究模糊综合评判方法的基础上,设计了Agent之间的冲突消解算法.最后,通过一个应用实例验证了系统的有效性.
