Résumé :
|
To date, the calibration of a numerical model has involved the subjective process of manually determining the optimum set of model parameters such that the model "best fits" observed data. The second stage described within this report includes: - further investigation on the behaviour of the "objective function" developed in SR 391 - development of other objective functions in order to reduce part of the subjectivity of the calibration procedure - evaluation of an automatic calibration procedure based on the Influence Coefficient Aglorithm.
