Extending discrete-event simulation frameworks for non-stationary performance evaluation: requirements and case study

This paper introduces an approach to obtain an empiric analytical model of the performance dynamics of computer systems out of discrete-event simulation (DES) experiments. To that end, the proposed methodology elicits the requirements for extending conventional stationary DES frameworks so as to meet the needs of transient performance analysis. The work goes through the rationales for the conceptual formulation of dynamic (as opposed to static) capacity and summarizes a methodology for system identification. Results of on going research are reported and conclusions illustrated by case study.
