【摘要】：為了引入動態(tài)定價機(jī)制、動態(tài)調(diào)整資源價格以提高資源提供商的競爭力,將動態(tài)定價組合反向拍賣方法引入云工作流資源分配中,設(shè)計(jì)了適于云工作流系統(tǒng)的組合反向拍賣模型,提出動態(tài)定價組合反向拍賣算法。通過基因序列工作流Epigenomics進(jìn)行對比實(shí)驗(yàn),結(jié)果表明固定價格時組合反向拍賣的時間費(fèi)用之積和拍賣次數(shù)比反向拍賣分別平均降低60%和17%,組合反向拍賣中動態(tài)定價的時間費(fèi)用之積比固定價格平均降低63%,資源利用率平均提高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%.
