    apprentissage Un méta modèle à nombre des paramètres minimal est alors la solution qui s impose 11 12 Les deux approches proposées dans ce WP sont ainsi complémentaires et permettront de proposer au futur utilisateur de la plate forme un choix des solutions Une réflexion profonde dans le domaine d application de chacune solution permettra également le guider vers une solution la plus adaptée à sa problématique 13 14 Il est important de noter que la construction d un méta modèle bien qu une étape importante n est pas dans la plupart des cas une fin en soi d une étude d incertitude Analyse de sensibilité WP 2 1 2 propagation à l aide de meta modèles WP 2 1 4 incertitudes dans des couplages hétérogènes WP 2 2 2 et estimation robuste des quantiles WP 2 2 1 en sont des bénéficiaires directs 15 16 Comment l utilisation d un méta modèle substituant le modèle lourd d un composant se répercuteratelle sur le résultat de l étude multi physique Dans quelle mesure dépende t elle de la quantité d intérêt de l étude Voilà les questions auxquelles ce WP répondra en prenant le pari de formalisme probabiliste 17 18 L objectif ici est de proposer un cadre générique de considération de ce type de problèmes Puis d en proposer des solutions répondant aux critères industriels contradictoires de robustesse et conservatisme contrôlé 19 20 Actuellement les solutions proposant de modéliser les interactions entre les sous systèmes commencent à immerger Processus Gaussiens Réseaux Bayesiens il reste toutefois à valider les résultats obtenus sur des exemples isolés pour le cas général et à asseoir un apport que ces approches ont par rapport à des méthodes plus classiques comme la propagation par Monte Carlo 21 22 Analyse de sensibilité WP 2 1 2 incertitudes dans des couplages hétérogènes WP 2 2 2 et estimation robuste des quantiles WP 2 2 1 sont des bénéficiaires directs de travaux de ce WP 23 24 WP 2 1 2 Analyse de sensibilité 25 26 Probablement le deuxième objectif le plus fréquemment rencontré dans les études d incertitude après l estimation robuste des quantiles probabilité de défaillance est l étude de la sensibilité En effet si le système ne satisfait pas le critère quelle est l action à entreprendre Celle qui élèvera à moindre coût les performances au niveau requis 27 28 Une étude de sensibilité montre dans quelle mesure la variable d intérêt et la quantité d intérêt sont influencée par chaque source variable d entrée du modèle Ainsi en augmentant la connaissance en réduisant l erreur de mesure en affinant la modélisation etc des sources les plus importantes on optimise les efforts 29 30 L étude de sensibilité peut aussi être vue comme un moyen mathématique de mettre en lumière les propriétés physiques du modèle devenant ainsi partie intégrante de la modélisation 31 32 Quelles sont les variables les plus importantes influençant la variable d intérêt étudiée Les interactions entre les variables existent elles sont
