Grid Resources Optimization Strategy Based on Utility Function
一种基于效用函数的网格资源优化策略

A model for resource broker-based service-oriented in grid resource management:SBAGRM presented.In this model,a utility functions-based grid resource allocation algorithm is proposed.The algorithm meet QoS requirement from user,it is to achieve the resource optimization which maximizes the system overall utilities.To avoid high computational complexity of nonlinear optimization problems,the preferableness and utility based SBAGRM problem are reformulated as market model to optimize resource allocation.So computational complexity is reduced.Simulation results show that improvement of performance is significant.
