Abstract

L'invention concerne un système de gestion associé à une ligne de fabrication comprenant une ou plusieurs installations. Chacune des installations est conçue pour traiter chaque pièce en fonction d'informations de commande comprenant la désignation par type d'objets à fabriquer et la désignation du nombre d'objets à fabriquer. Le système de gestion comprend : un moyen de collecte pour collecter des informations d'évènement concernant un processus qui a lieu dans chacune des installations; des moyens de classification pour classer, sur la base d'une source de génération et du contenu de chaque élément d'informations d'événement, les informations d'événement collectées par le moyen de collecte, en ensembles d'informations d'événement générés pour la même pièce; un moyen de génération pour générer des données qui représentent des circonstances de processus pour chaque pièce sur la base des informations d'événements appartenant à chacun des ensembles classés par les moyens de classification; et un moyen de visualisation permettant de visualiser des circonstances de progression de processus pour chaque pièce traitée selon les informations de commande, sur la base des données générées par le moyen de génération.
