【摘要】：为了引入动态定价机制、动态调整资源价格以提高资源提供商的竞争力,将动态定价组合反向拍卖方法引入云工作流资源分配中,设计了适于云工作流系统的组合反向拍卖模型,提出动态定价组合反向拍卖算法。通过基因序列工作流Epigenomics进行对比实验,结果表明固定价格时组合反向拍卖的时间费用之积和拍卖次数比反向拍卖分别平均降低60%和17%,组合反向拍卖中动态定价的时间费用之积比固定价格平均降低63%,资源利用率平均提高69%。
[Abstract]:in order to introduce the dynamic pricing mechanism, the resource price is dynamically adjusted to improve the competitiveness of the resource provider, the dynamic pricing combined reverse auction method is introduced into the cloud workflow resource allocation, a combined reverse auction model suitable for the cloud workflow system is designed, A dynamic pricing combined reverse auction algorithm is proposed. The results show that the time cost of the combined reverse auction at the fixed price is 60% and 17% lower than that of the reverse auction, respectively. The product of the time cost of the dynamic pricing in the combined reverse auction is 63% lower than the fixed price, and the utilization rate of the resource is increased by 69%.
