Manufacturing grid resource and resource service digital description

摘要

The core of manufacturing grid (MGrid) is resource service sharing and optimal allocation (RSSOA), including: (a) match and search of resource service; (b) QoS modeling and evaluation of resource service, (c) resource service optimal selection and composition, (d) failure detection and recovery, etc. The foundation to realize the above operations of RSSOA is digital description of resource service (DDoRS). Without digital describing information of resource service, the operations of RSSOA would have no data and information supports. Hence, DDoRS is one of the key issues for addressing RSSOA. The problem of DDoRS in MGrid is investigated in this work. The definition of MGrid resource service is given out, associated with the corresponding resource service classes. A three-step method for establishing an MGrid-Ontology is proposed and an MGrid-Ontology is established. A new digital description method for MGrid resource service based on MGrid-Ontology is put forward. A case study is described to illustrate how the proposed works can be used to MGrid resource service management.
