Utilisation de données historiques pour caractériser le millésime en cours

Abstract

Cet article propose la formalisation d’un modèle paramétrique pour représenter l’accumulation des sucres dans les baies de raisin durant la maturation. Le test de ce modèle sur des jeux de données réels a permis de valider l’approche proposée. Une seconde partie est axée sur l’adaptation de la méthode pour permettre la simulation du comportement du millésime en cours dès les premiers relevés de maturité. Ce travail possède de multiples applications dans le domaine de l’aide à la décision. English version: This paper proposes the formalization of a parametrical model in order to represent sugar accumulation in grape berries during ripening. The model was tested on real data and provides results that enable the validation of the proposed approach. The second part is based on the method accommodation to simulate the behavior of the current vintage as soon as the first maturity measurements are available. This work could have several applications in the decision support field.
