摘　　要：云计算环境下信任机制对任务调度过程中的内在机理研究还不够深入,导致任务完成率受信任主体的效益值影响较大。为了探索信任效益值与任务调度的关系,提出了一种动态信任效益任务调度算法。该算法采用信任效益函数量化不同信任关系下调度结果对任务完成时间与完成率的影响。仿真实验结果显示该算法在任务完成时间、任务完成率、信任效益值等多个性能方面均优于其他传统的任务调度算法。The internal mechanism of the trust mechanism in task scheduling is not deep enough in Cloud computing environment,which leads to the efficiency of the task completion rate is greatly affected by the benefit value of the trust mechanism.In order to explore the relationship between trust benefit value and task scheduling,a dynamic trust benefit task scheduling algorithm is proposed.The proposed algorithm uses the trust benefit function to quantify the effect of scheduling results on task completion time and completion rate under different trust relationships.The simulation results show that the proposed algorithm is superior to the other traditional task scheduling algorithms in completion time,task completion rate,and the trust benefit value.
