中文摘要：
基于市场机制提出了一种以资源代理为基础、面向服务的网格资源管理模型——SBAGRM。在该模型的框架下提出了一种基于效用函数的网格资源分配方法，该方法以满足用户的QoS需求为出发点，旨在追求系统资源的全局最优化。SBAGRM模型可以避免非线性优化带来过高的计算复杂度，以市场模式根据效用函数配置资源，因此计算复杂度将大大降低，模拟结果显示性能明显提高。
英文摘要：
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 resuhs show that improvement of performance is significant.
