摘　　要：制造网格资源共享可归纳为资源提供与应用两方面,资源发现贯穿其中是其关键。从资源发现角度,从两个层面提出制造网格ASP模式的资源发现组成结构:在制造网格体系结构层面,提出以通用企业服务中心为核心的结构;在应用服务供应商的网络分布结构层面,提出了一种多层树型覆盖网络结构。两个层面相互支持,为资源发现提供无缝结构支持。该结构能实现分层检索、广域多点发现,并具有面向企业、面向应用等特性。基于上述结构,给出了资源发现并行算法及其性能分析,并用量化示例及其部分实现说明了该结构的有效性。Resource sharing on manufacturing grid （MG） consists of two parts： resource supply and resource application, which are connected by resource discovery. From the perspective of resource discovery, composite structure of resource discovery based on Application Service Provider （ASP） pattern of MG was proposed from two levels： first, on architecture of MG, one structure based on a general enterprise service center was proposed; second, on deployment architecture of ASP, architecture of multi-level and tree overlay network was proposed. They support with each other and provide support of seamless structure for resource discovery. This structure can realize lamination retrieval and multi-spot resource discovery in broad area and has features such as being enterprise-oriented and application-oriented and so on. Based on the architecture above, one parallel algorithm of resource discovery was designed whose performance was analyzed and compared with other algorithm. Finally, validity of this architecture is powerfully illustrated with a qualified example and realization about some parts of the architecture.
