摘　　要：针对当前教学设备能效产出模型与度量方法未考虑教学设备功率的动态性,导致构建的能效产出模型无法充分反映云计算环境下教学设备整体能效的弊端,提出了一种新的云计算环境下教学设备能效产出模型与度量方法.通过“性能”和“能耗”两个指标对云计算环境下教学设备的能效进行综合评价,用单位时间教学设备的总“性能”与总“能耗”之比对能效进行描述,并构建教学设备能效产出模型.并设计实验从准确性、效率、精度、误差与适应度上验证了所提能效产出模型优于QoS模型与智能模型,进而得出所提产出模型与度量方法能够较准确地评估云计算环境下教学设备的能效,并为后期对教学设备能效进行优化夯实基础.Since the present energy efficiency output model and measurement method for teaching equipment leave out of consideration the dynamic nature of the power of teaching equipment,the constructed energy efficiency output model cannot fully reflect the overall energy efficiency of teaching equipment in the cloud computing environment.In view of this defect,a new energy efficiency output model and measurement method for teaching equipment in cloud computing environment are proposed.With two indicators of"performance"and"energy consumption",comprehensive evaluation is carried out on the energy efficiency of teaching equipment in cloud computing environment,the energy efficiency is described by the ratio of"performance"to"energy consumption"of teaching equipment per unit time,and the energy efficiency output model of teaching equipment is built.Furthermore,experiments are designed to verify that the proposed energy efficiency output model is superior to QoS model and intelligent model in terms of accuracy,efficiency,precision,error and fitness.Then it is concluded that the proposed output model and measurement method can accurately evaluate the energy efficiency of teaching equipment in cloud computing environment,which lays a solid foundation for future optimization of the energy efficiency of teaching equipment.
