面向制造网格的应用平台及虚拟企业建模研究

在分析制造网格、计算网格和网络化制造之间差异的基础上,探讨了面向制造网格的应用平台及虚拟企业 建模等问题。首先,分析了制造网格和网络化制造在资源组织和应用模式上存在的差异,提出一种面向制造网格 的应用框架;其次,研究了制造网格相对于计算网格所具有的多变业务目标、多级资源共享、资源服务的提供和 结果提交的在线和离线混合方式的特点,形成了制造网格的应用内涵;然后,在剖析计算网格、基于资源服务的 制造网格以及应用程序等基础上,形成了从业务链、资源服务链到网格节点链的处理过程,并最终导出了面向制 造网格应用的虚拟企业的组织模型。最后,通过对问题的量化描述了应用平台的处理过程和算法。上述研究对于 推动制造网格的应用和虚拟企业的组织建模具有积极的意义。

Research on application platform and virtual enterprise modeling for manufacturing grid

By analyzing the difference between manufacturing grid and computing grid, and the limitation of networked manufacturing, application platform and virtual enterprise modeling for manufacturing grid is presented. Firstly, the difference of resource organization and application between manufacturing grid and networked manufacturing is surveyed, and the application platform for manufacturing grid is recommended. Secondly, the application features of manufacturing grid compared with computing gird is researched, such as dynamic business objective, hiberarchy resource sharing, online and offline pattern, submission mode of service result etal., and the connotation of manufacturing grid is also described. Thirdly, by analyzing the different parts of application platform, the operation process from business-chain, resource-service-chain to grid-node-chain is derived and virtual enterprise modeling was constructed based on grid node chain. Finally, the process and algorithm is illustrated with a quantify example. Above Research is benefit for application of manufacturing gird and modeling of virtual enterprise.
