摘　　要：在研究现有云计算服务调度算法的基础上,设计了基于QoS的分布式多目标服务调度算法。该算法兼顾用户需求和系统整体性能,依据完成时间、费用、开销和负载均衡多个参数进行服务调度,从而获得较好的调度质量。仿真实验表明该调度算法能够满足云用户的QoS要求,调节云内各种设备的负载均衡,提高云计算平台运行效率。Based on the study of existing cloud computing services scheduling algorithm, a QoS- based distributed multi-target service scheduling algorithm was designed and achieved. This algorithm considers the user needs and the overall performance of the system, on the basis of the completion time, cost, overhead and load balancing multiple parameters for service scheduling to obtain better scheduling quality. Experimental results show that the scheduling algorithm not only meets the user＇s QoS requirements of clouds, but also adjusts the load balancing and improves the operating efficiency of cloud computing platform.
