Abstract[English]
The invention relates to a method for generating an optimized production scheduling plan for processing of workpieces in a Flexible Manufacturing System The basic idea of the invention is to observe the behavior of the scheduling system that is currently used within the production system, learn from the observations, and optimize where necessary. This will be done while training a Deep Reinforcement Learning (RL) System for an online scheduling system. The solution supports different local and global optimization goals, e. g. makespan minimization or capacity utilization, which can be adapted independently for each manufactured product[French]
L'invention concerne un procédé de génération d'un plan de planification de production optimisé pour le traitement de pièces dans un système de fabrication de flexible, l'idée de base de l'invention étant d'observer le comportement du système de planification qui est actuellement utilisé dans le système de production, de tirer parti des observations, et d'optimiser si nécessaire. Ceci sera réalisé tout en entraînant un système d'apprentissage de renforcement profond (RL) pour un système de planification en ligne. La solution prend en charge différents objectifs d'optimisation locaux et globaux, par exemple une réduction de la durée d’exécution ou une utilisation de capacité, qui peuvent être adaptées indépendamment pour chaque produit manufacturé.
