Une unité de calcul de nombre de composants restants (18) d'un appareil de gestion des stocks (1) selon la présente invention soustrait un nombre de composants électroniques montés sur une carte de circuit électronique par un appareil de montage de composants électroniques d'un nombre de composants électroniques contenus par l'appareil de montage de composants électroniques chaque fois qu'une unité d'acquisition de signal de détection (17) acquiert, auprès de capteurs (2A) et (2B) servant à détecter le déchargement d'une carte de circuit électronique sur laquelle des composants électroniques ont été montés par l'appareil de montage de composants électroniques, un signal de détection qui indique qu'une carte de circuit électronique a été déchargée, calcule un nombre restant de composants électroniques contenus par l'appareil de montage de composants électroniques, et calcule, à partir du nombre restant de composants électroniques, le temps avant un instant de réapprovisionnement en composants électroniques. Une unité de génération d'instruction de réapprovisionnement (21) génère des informations d'instruction de réapprovisionnement ordonnant le réapprovisionnement en composants électroniques de l'appareil de montage de composants électroniques dans le cas où il existe un appareil de montage de composants électroniques dans lequel le temps avant l'instant de réapprovisionnement en composants électroniques calculé par l'unité de calcul de nombre de composants restants (18) est inférieur ou égal à une valeur seuil, et une unité de sortie d'instruction de réapprovisionnement (22) délivre les informations d'instruction de réapprovisionnement.
