摘要: 针对ASKALON网格工作流管理系统中缺乏对服务质量组合方面的研究,基于AGWL网格工作流模型,提出了一种网格工作流服务质量的估算算法。该算法的主要特点是:1)基于AGWL语言;2)可扩展的QoS度量;3)多维全局QoS度量。最后,用仿真实验验证了该算法的可行性。

Abstract: With regard to the lack of research for QoS composition in ASKALON grid workflow management system, this paper presented a QoS estimation algorithm for grid workflow based on Abstract Grid Workflow Language (AGWL) grid workflow model. Three main features of the algorithm are: 1) Based on AGWL; 2) Scalable QoS metrics model; 3) Multi-dimensional global QoS metrics. Lastly, the feasibility of the algorithm is validated through simulation experiment.
