| 摘 要： | 提出了QoS感知的多任务服务优化组合非合作博弈模型,准确刻画了不同任务之间的竞争关系,在此基础上设计了顾及QoS的遥感信息服务优化组合反应函数,为求解遥感信息服务优化组合奠定理论基础。理论和实验分析表明,该模型有利于减少任务并发时的资源冲突,最大化所有任务的平均效用。

| Abstract: | A non-cooperative game model for QoS-aware optimal composition for multi-task is proposed to analyze services optimal composition strategies of tasks in competition situation,the competition relationships among concurrency tasks are described,and defines the best reply functions for QoS-aware optimal composition of remote sensing information services.Theoretical analysis shows that the proposed non-cooperative game model can reduce the conflicts among concurrency tasks effectively and maximize expectation utility of all tasks. |

| Keywords: | remote sensing information services QoS aware optimal composition |
