Optimal Allocation Of Manufacturing Grid-based Virtual Enterprise Manufacturing Resources

Virtual Enterprise is a advanced manufacturing organizational form which was proposed to adapt to rapid response. Manufacturing resources scheduling process is the important stages in virtual enterprise operations. Manufacturing resource scheduling process of Virtual enterprise is important in enterprise operations. Improvements of scheduling efficiency will greatly improve the overall operational efficiency of virtual enterprise. In the current network conditions, the virtual enterprise operations are lack of a reliable and effective mechanism for manufacturing resource management. So manufacturing resources information of member enterprises is hard to control and virtual enterprise manufacturing resource efficient scheduling is not achieved. Compared with the existing network, grid is characteristics of scalability, interoperability, adaptiveness and dynamics. Using resources search function and information services which grid provides, virtual enterprise can be organized rapidly and response quickly in view of application request. Grid will be used in manufacturing resource scheduling of Virtual Enterprise, that help strengthen the controlling information and state of manufacturing resource of Virtual Enterprise. Resource scheduling platform based on the manufacturing grid, manufacturing grid resource modeling and manufacturing resources optimization and matching were researched in view of several key issues in resource scheduling of virtual manufacturing enterprise in this paper. Its main contents and the results are as follows:(1) Virtual enterprise resource scheduling platform based on the manufacturing grid was researched. Resource scheduling platform architecture was proposed on the basis of manufacturing grid. Platform model was designed based on agent technology and the Globus Toolkits, and then platform workflow was given.(2) Manufacturing grid resource descriptions and encapsulation were researched. From the point of resource sharing, resource classification, attributes, relationships and resource levels were taken into consideration to descript manufacturing resource, which are in support of manufacturing resources optimization and matching.(3) Study on Manufacturing Grid-based virtual enterprises optimize the allocation of resources to create grid-based virtual enterprises achieve a higher level of shared resources, optimize the allocation of its resources into a resource node selection problem, a two-stage manufacturing resource nodes preferred method. Resources in determining the candidate node stage, put forward in the manufacture of manufacturing grid search method the level of resources, by group and cluster resources to improve the efficiency of resource retrieval, TQCS based on the best manufacturing resources of the local search, to determine the optimum node resources. Combinatorial optimization at the stage of resources, compromise the use of genetic algorithm for multi-objective optimization, in order to determine the best combination of resources...
