Research Of Grid Resource Distribution Based On Fuzzy Multi-objective Decision Makings

Grid computing is one of the most attractive research fields currently, which enables all the geographically distributed resources to be widely shared and collaborate, such as high-speed Internet, mainframes, large-scale databases, sensors, remote devices, etc. Because of its distributiveness, heterogeneity, dynamic, and possessed by many organizations and distinct using, accessing, mode of charge, etc, resource distribution under grid environment is very difficult. Resource distribution has been one of the key research fields of grid systems.Resource selection is strategic decision-making of grid resource distribution. Resource distribution is responsible for providing the best resource services according to user's requirement. But user's request has much fuzzy actually. So quality of grid service is hardly to meet user's needs.In this paper the basic concepts of grid computing, characteristic, currently research status, the popular grid infrastructures and typical grid system were introduced. A new strategy of resource distribution based on Fuzzy Decision Makings was provided, and a model of Multi-objective Fuzzy Decision Makings was built to solve the resource distributing problems in grid computing. Also implement of the strategy was described in the thesis. Analysis proved that this model not only provided the best resources to tasks, but also enhanced the successfulness of resource matching and the efficiency of resource using.
