摘要: A Global Sensitivity Analysis procedure is presented to efficiently rank influence strength of model parameters upon the functional outputs. modified Morris one-at-a-time algorithm used for parameter sampling. Simulated responses are transformed into global sensitivity functions using response discretization and a scalar Index. Two indices tried — reference mean absolute value elementary effects an alternative index proposed here. Finally, aggregated measures formed, suitable ranking parameters. The two variants total based method compared circuit infra-red photo-detector front end. Accuracy advantage performance shown.
