Abstract

Dispositif d'attribution de véhicule de transport automatique (15) destiné à attribuer des véhicules de transport automatique (V) pour transporter des fournitures vers des machines de montage de surface (M), les machines de montage de surface (M) comportant des machines de montage compatibles avec un réapprovisionnement automatique (M) qui prennent en charge un réapprovisionnement automatique de fournitures, et des machines de montage de réapprovisionnement non automatique (M) qui ne prennent pas en charge le remplissage automatique de fournitures ; et les véhicules de transport automatiques (V) comportent des véhicules de réapprovisionnement automatique (V) qui présentent une fonction consistant à réapprovisionner automatiquement les machines de montage compatibles avec un réapprovisionnement automatique (M) avec des fournitures, et des véhicules de réapprovisionnement manuel (V) qui ne présentent pas de fonction destinée à rapprovisionner automatiquement les machines de montage compatibles avec un réapprovisionnement automatique (M) avec des fournitures. Le dispositif d'attribution de véhicule de transport automatique (15) est doté d'une unité de communication (32) qui communique avec les machines de montage de surface (M), et d'une unité de commande (30), l'unité de commande (30) réalisant : un processus de réception destiné à recevoir une requête pour réapprovisionner des fournitures à partir d'une machine de montage de surface (M) par l'intermédiaire de l'unité de communication (32) ; et un processus d'attribution destiné à attribuer un véhicule de transport automatique (V) pour transporter des fournitures vers la machine de montage de surface (M) demandant le réapprovisionnement, dans le processus d'attribution, si la machine de montage de surface de demande (M) est une machine de montage compatible avec un réapprovisionnement automatique (M), un véhicule de réapprovisionnement automatique (V) étant attribué de manière préférentielle.
