虚拟制造组织中服务定位机制研究

Service Location Mechanism of Virtual Manufacturing Organization

提出一种基于公共对象请求代理结构(CommonObjectRequestBrokerArchitecture,CORBA)的多自主体系统(Multi agentSystem,MAS)体系结构作为虚拟制造组织(VirtualManufacturingOrganization,VMO)的组织框架和信息基础设施,以跨越成员企业之间在位置、网络、协议、平台、语言以及数据结构和类型等方面的异构性,实现在语义和应用层上的互操作。在此基础上提出一种基于中间Agent的服务定位机制(ServiceLocationMechanism,SLM),以支持虚拟制造组织的构建以及成员企业间的通信、互操作和资源/服务共享,并在开发的VMO概念原型系统上进行了实现和验证。

This paper presents a multi-agent system architecture that is based on common object request broker architecture(CORBA).The architecture is used as the organizational framework and the IT infrastructure of virtual manufacturing organization(VMO)to achieve interoperation at semantic and application levels among enterprises,ragardless of their heterogeneous in location, network,protocol,platform, language,as well as data structure and data type. A middle agent-based service location mechanism(SLM)is proposed to support forming a VMO and for VMO members to communicate,to interoperate and to share resources and services.SLM is implemented and tested with a concept prototype system developed in the paper.
