Abstract

L'invention concerne un système et un procédé d'amélioration de la productivité au moyen d'un dispositif d'identification par radiofréquence (RFID). Un réseau RFID comprenant, par exemple mais non limitativement, un certain nombre de lecteurs, un contrôleur, un central téléphonique et un serveur est placé dans l'usine. La carte RFID d'identification du travailleur et la carte RFID de la pièce à usiner sont insérées dans le lecteur, où l'information est lue avant d'être envoyée au contrôleur. Le serveur reçoit l'information recueillie concernant la chaîne de production en provenance du contrôleur en vue de l'élaboration d'un classement et de statistiques d'après l'information. Selon les statistiques, le serveur rétablit la relation entre la carte RFID de la pièce à usiner et le numéro de la pièce, gère le déroulement du travail, génère une information sur l'historique concernant le travail de l'ouvrier et calcule la durée standard de production de la pièce afin d'identifier le goulot d'étranglement de la chaîne de production. L'invention recueille des données sur la chaîne de production en temps réel, assure le bon déroulement des opérations, améliore la productivité sans pour autant avoir recours à des cartes en papier comme dans l'art antérieur. On réduit ainsi la charge de travail du gérant et du service des finances occupés à calculer le travail au moyen des cartes en papier.
