A novel quantitative model for system performance based on distributed IT management structure

At present, large enterprises have a lot of branches Although the IT system can be in the form of centralized data center, but the business sector and branch structure itself cannot centralized like IT. Therefore through standardized ITIL processes to achieve centralized management of IT infrastructure opaque organization. But the process appeared on the "performance" of the problem regarding the evaluation of non-uniform standards, leading IT service efficiency optimization bottleneck. For this issue, this paper studies the current IT performance indicators and analyze cause of the problem, and then use statistical data, designed to quantify the performance of an innovative assessment model based on distributed IT management framework. Finally, check the massive performance data through the assessment model, using simulation to fully verify the feasibility of the model.
