Therefore, when are created managed using processes, underlying workflow engine must accept specifications able estimate, monitor, control rendered customers. this paper, we present predictive model that makes it possible compute automatically based on atomic task attributes. We also implementation our METEOR system. describe components changed added, discuss how they interact enable QoS.
