Study on manufacturing grid & its resource service optimal-selection system

The concept of manufacturing grid (MGrid) is to utilize manufacturing resources distributed in heterogeneous systems and different places to collaboratively manufacture products the market requires. The solution is based on adopting grid technologies, information technologies, advanced manufacturing technologies, management technologies, etc., to realize the complete sharing of all kinds of geographically distributed and heterogeneous manufacturing resources in the form of virtual enterprises. After summarizing the grid technology and its applications, we propose the concept of MGrid. The application of grid technology in manufacturing and the related works about MGrid are investigated. The connotation of MGrid are put forward, including its basic features, the structure and main functions, the main research contents, the architecture, and key technologies. A resource service optimal-selection system of MGrid and its main functions are researched, including resource service description, resource service publication, resource service discovery, resource service quality of service (QoS) evaluation, and resource service optimal-selection evaluation. An application prototype, namely magnetic bearing resources sharing and service platform under manufacturing grid, is developed. It validates the resource service sharing and optimal-selection system in MGrid.
