Research On Architecture And Resource Management For Manufacturing Grid System

The essentially feature of grid is the share and cooperation of the resources. With theapplication and the research of grid in science and computation, it has been applied in manyfields such as science, business and industry. Because between the support of grid and therequirement of networked manufacturing is coincident. Grid is looked as a key technique innetworked manufacturing to construct manufacturing grid system supporting manufacturingenterprises cooperation. MG can realize the whole connectivity of software and hardwareresources what manufacturing involved on net. It has important function to optimalconfigure the manufacturing resources, increase the competence of middle and smallcorporations and accelerate the cooperated product exploitation course. The architectureand the method of resource management in manufacturing grid system are researched inthis paper.The complexity of manufacturing resources and manufacturing grid system requireconstructing the architecture. The requirement of manufacturing grid and its features areanalyzed and the system architecture is constructed in this paper. The manufacturingresources are the most important elements in manufacturing grid system. So, researching onthe manufacturing resources management is the key content about manufacturing gridsystem.Constructing the uniform models is the basic of resource management, searching andscheduling. On the basis of analyzing the features of resources and classifying them in themanufacturing grid system, the resource information model, data model, structure model,information management model and named model are constructed. These models modeleand describe uniformly the manufacturing resources from different view using many modelmethods. They provide dependence to uniform manage and optimal configure the resourcesin manufacturing grid.The method of resource searching and optimal configuring is the key to obtain therequired resource. Hiberarchy-searching method is proposed in this paper. The methodincreases the efficiency of resource searching by grouping and clustering them. Geneticarithmetic is used to optimal configure the manufacturing resources combination. Theinstance testified that the hiberarchy-searching method is correct, efficient and practical. Inthe mean time, the method has low time-complexity and space- complexity compared to the other resource searching methods. It fits to the complex and multiplex manufacturingresources in manufacturing grid.The resource-scheduling policy is researched and the resource-scheduling model isbuilt. The uniformed method of encapsulating and describing the resource, task and theresult of task executed is the precondition to resource scheduled. So, how the resources areencapsulated to manufacturing service and how the status of the service and the charactersof task are described are discussed in this paper. In the mean time, the resources conflictionproblem of resource selecting or scheduling is discussed. The method of solving theconfliction of device resource in manufacturing grid is proposed.On the basis of above research, a manufacturing grid resource management system isdeveloped. The implement environment and method of the system are stated at the last ofthis paper and the resource management and optimal configure algorithm are testfied.
