Analyzing Resource-Usage Impact on Component-Based Systems Performance and Reliability

An early prediction of resource utilization and its impacton system performance and reliability can reduce theoverall system cost, by allowing early correction of detectedproblems, or changes in development plans with minimizedoverhead. Nowadays, researchers are using both academicand commercial models to predict such attributes, by measuringthem at earliest stages of system development. Inthis paper, we give a short overview of existing predictionmodels for performance and reliability, targeting popularcomponent-based frameworks. Next, we describe our ownapproach for tackling such predictions, through an illustrationon a small example that deals with estimations of energyconsumption.
