The realization method and application of resource sharing in manufacturing grid

Abstract

Networked manufacturing is essentially a kind of information sharing, and e-manufacturing is the extension and outspread of networked manufacturing and e-commerce. The key which manufacturing develops in network environment lies on realizing manufacturing resource sharing and collaboration under the distributed environment. Manufacturing grid (MG), which was the application of grid technology and information technology, provided a feasible way for the manufacturing resource sharing and collaboration in the distributed environment. The WSRF (Web service resource framework)-based MG resource sharing architecture was proposed. With this architecture, by constructing resource description model, a manufacturing resource can be encapsulated to a WS-resource service and deployed on the MG, thus the heterogeneous and geographical distributed resource sharing can be realized. With a QoS (quality of service)-based resource searching and scheduling, the resource discovery and scheduling combining with all or part of the TQPS (time, quality, price, service) properties can be implemented, so the optimal manufacturing service can be provided for the MG customers. Finally, an application on rapid prototype resource was taken as an example to illustrate the practicability and feasibility of the architecture.
