Abstract

Selon l'invention, lorsqu'une unité de planification d'usinage (15) d'un dispositif de gestion de production (1) dans un système de gestion de production (100) détermine qu'il existe une pluralité d'équipements d'usinage (4) soumis à un calcul qui sont exécutés et qui sont capables d'exécuter un processus à attribuer, une unité de calcul de temps de travail moyen (12) calcule un temps de travail moyen pour chaque élément d'équipement d'usinage (4) soumis à un calcul sur la base d'informations relatives aux résultats de production. Pour chaque élément d'équipement d'usinage (4) soumis à un calcul, une unité de calcul de temps de mouvement (13) calcule le temps de mouvement d'un dispositif de transport (2) vers l'élément d'équipement d'usinage (4). Une unité de calcul de moment d'achèvement planifié (14) calcule un moment d'achèvement planifié d'une tâche pour chaque élément d'équipement d'usinage (4) soumis à un calcul sur la base du temps de travail moyen, du temps de mouvement, et d'un moment de traitement possible. L'unité de planification d'usinage (15) attribue le processus à l'élément d'équipement d'usinage (4) qui présente le moment d'achèvement planifié le plus tôt et transmet, à un dispositif de gestion de transport (3), des informations de transport indiquant l'élément d'équipement d'usinage (4) auquel le processus a été attribué. Le dispositif de gestion de transport (3) transmet, au dispositif de transport (2), une instruction de mouvement pour transporter un article d'alimentation pour le processus vers l'équipement d'usinage (4) indiqué par les informations de transport.
