摘要: 基于經濟模型研究網格服務質量(QoS)控制的資源分配問題,給出了多QoS屬性多任務的資源分配優化的效用模型.該效用模型描述了網格任務的動態需求和偏好,以效用最大化為目標計算了需要提供QoS的資源分配.設計了時間和預算限制條件下基于多QoS屬性的聯合效用函數調度算法,并與其他經濟的和非經濟的算法進行比較,驗證了該算法的有效性.Abstract: The economic model was applied to solve the QoS (quality of service) guarantees problem, and a utility model expressed in multi-QoS attributes was presented, which can be used to dynamically allocate resource in the Grid. A multi-QoS attributes-based joint utility function scheduling (JUFS) algorithm under the deadline and budget constrain was proposed. The performance of the algorithm was evaluated through a series of simulations. Comparisons with other economic and non-economic algorithms show that the performance of the JUFS algorithm matches well with the service on demand in the Grid.
