Abstract

La présente invention concerne un procédé d'évaluation de l'avantage de solutions de commande perfectionnées. Le procédé de l'invention consiste à estimer les distributions statistiques des variables et des paramètres du procédé ou de l'ensemble fonctionnel associé, et à déterminer le système de référence du procédé pour estimer les performances de référence du procédé ou de l'ensemble fonctionnel associé. En outre, pour estimer les performances améliorées du procédé ou de l'ensemble fonctionnel associé, par rapport aux performances de référence, on utilise le système de référence en tenant compte des effets de la distribution statistique réduite des variables et des paramètres sur le procédé et/ou des effets de solutions de commande perfectionnées et de l'optimisation associée.
