Abstract

Il est difficile de gérer avec précision la fabrication dans une chaîne de fabrication comprenant une ou plusieurs étapes qui nécessitent un travail humain. La présente invention porte sur un système de gestion de fabrication qui accepte une entrée d'un code d'identification associé à une instruction d'opération concernant au moins une première étape pour chaque produit introduit dans la ligne de fabrication, identifie, pour chaque étape, des détails d'opération associés au code d'identification accepté, et affiche un écran indiquant le code d'identification et les détails d'opération sur le terminal d'un opérateur. Le système de gestion de fabrication accepte une entrée concernant le début et la fin de l'étape, et enregistre l'instant de début et l'instant de fin en tant qu'informations de gestion. Le système de gestion de fabrication affiche un écran servant à afficher un résultat d'opération sur la base d'un temps d'opération allant de l'instant de début à l'instant de fin de chaque étape sur le terminal d'un responsable sur la base des informations de gestion.
