摘要
Based on open grid service architecture (OGSA) and Globus Toolkit 3. 0 (GT3), a manufacturing grid (MG) is proposed to realize resource sharing and collaborative working among manufacturing enterprises. Nevertheless, resource management in MG is much more complicated than that in other grid applications due to the geographically distributed manufacturing resources, which range from CAD, CAPP and CAE to various kinds of machine tools. With the interaction of manufacturing grid information service (MGIS, developed by ourselves) and globus resource allocation manager (GRAM, provided by GT3), a resource management framework is presented to perform the functions of resource encapsulation, registry, discovery and monitoring. Furthermore, the application architecture and an example are depicted to illustrate the utilization of the resource management system.
为实现制造业的资源共享和协同工作 ,以开放网格服务架构 (OGSA)为系统框架 ,以GT3(GlobusToolkit 3.0 )为开发工具 ,提出了制造网格的概念 .然而 ,由于制造资源的复杂性、多样性、特殊性和分散性 ,制造网格中的资源管理问题明显比其他网格应用项目困难得多 .因此 ,开发了制造网格信息服务 (MGIS) ,该服务通过有效集成检测查询服务 (MDS)和各种类型的资源封装模板 ,实现了制造资源的远程封装、注册、发现和监控 .同时 ,MGIS与GRAM(globusresourceallocationmanager)共同构建了制造网格的资源管理系统 ,解决了制约制造网格应用的瓶颈问题 .最后 ,给出了该系统的应用框架 ,并通过制造网格试验床中的一个具体应用实例说明了其实际应用过程 .
