基于粒子群遗传算法的云计算任务调度研究
对云计算任务调度进行了研究，针对用户满意度和云提供商利益需求，提出一种融合粒子群和遗传算法的PSOGA改进算法。首先根据云环境特点对虚拟机资源进行分类，同时引入任务‐资源满意度距离、资源综合性能概念；然后对粒子群初始粒子操作进行优化，来提高粒子质量；最后为克服粒子易陷入局部最优解问题，加入遗传算法（GA）的交叉、变异操作，扩展粒子的搜索空间。仿真结果表明，该调度策略提高了用户满意度的同时减少了任务的完成时间，是云平台下一种有效的任务调度策略。Computer engineering and applications[0,1]Ka By+M=85,7,4,7,41 aya+B+rBr0.10.20.7(9,1,25,7)(9,25,5,7)=(1,0,0,1,1)3 a oB∑01(1,0,1,1)④0.9(1,1,0,1)=(1xx,1)010.109(3,2,1,5,4)∞(1,0,1,1,1)=(3x,15,4)GA3.2Computer engineering and applications0.36Cloudsim 3.0CloudsimDatacenter Brokerbind cloudlettovm=0.82bind CloudlettovmMyclipse100PSOGAPSOGAK=844%Cloud[1000040000rand([150,200rand()]预处理任务及資、「5001000rand(]源,并更新虚拟机计算任务-资谅满总度距离[60100rand()ndo初始负载从可用资源随机生|根据得致的任务最PSOGA成S3/4个子佳虚拟机类型生成S/4个粒子PSOPSOGAGA初始化S个粒了的还200度,并设置最大迭代次数L和 fitness=tPSOGA很据車新定义的粒了探作,计算 fitness值,并更新pb利gb根据规则选择粒了进亻[15交叉变异探作,并计算fitness值,更新忡群(12)达到最大次效LL=L+1fitness阈值结太,得到最优解(13)M=200300200200LPSOs Lo n PsoGAPSOGAPSOGAGAComputer engineering and applications80070600s■PSO400AGA300■ PSOGA200PSOGAPSO GA100PSO GA0第一批第二批第三批PSOGAPSO GAPAOGAPSOGA2.5PSOPSOGAA0.5PSOGA第一北第二批第批PSOGAPSO GA5400190r170015001301100西GAn□1sGAGA了0050o笫一批第二批第二批43.532.5NGA□05第一枇第二批第三批Computer engineering and applications基于粒子群遗传算法的云计算任务调度研究万F据WANFANG DATA文献链接作者王菠,张晓磊作者单位:重庆人学计算机学院,重庆400044刊名:计算机工程与应用英文刊名:Com uter Engineering ar d Appl ications年,卷(期)2013Axfe:http://d.wanfangdata.concn/periodiCalpre8fb5c222-8042-4959-ba95-2a3a31f59b2e.aspx

风电场风速和发电功率预测研究.pdf
风速预测对风电场和电力系统的运行都具有重要意义。对风速进行比较准确的预测，可以有效地减轻或避免风电场对电力系统的不利影响，同时提高风电场在电力市场中的竞争能力。基于时间序列法和神经网络法，该文对风速预测进行了研究，提出了预测风速的时序神经网络法。该方法用时间序列法建模，得到风速特性的基本参数，并用这些参数选择神经网络的输入变量；为了提高预测精度，提出了滚动式权值调整手段。该方法有效地提高了风速预测的精度。
