Title (EN) SYSTEM AND METHOD FOR MONITORING A MANUFACTURING PLANT
(FR) SYSTÈME ET PROCÉDÉ DE CONTRÔLE D'UNE INSTALLATION DE FABRICATION
Abstract:
(EN) A manufacturing process system comprises any number of assembly stations and test stations, a model unit, and any number of final products is provided. Any of a sample test method and the statistical distribution monitoring method performed by the model unit is configured to monitor the model quality after it is deployed and reduce potential unnecessary costs, such as warranty claim costs as a result of sending bad units to the customers, and rework costs as a result of predicting a good part as bad and wasting additional testing efforts on the bad parts. Further, both methods are configured to maximize the probability of detecting hazardous issues, while having control of the false alarm rate.
(FR) L'invention concerne un système de traitement de fabrication qui comporte un nombre quelconque de postes d'assemblage et de postes d'essai, une unité de modèle et un nombre quelconque de produits finaux. L'un quelconque parmi un procédé d'essai d'échantillon et un procédé de contrôle de distribution statistique effectué par l'unité de modèle est configuré pour contrôler la qualité de modèle après son déploiement et pour réduire les coûts inutiles potentiels, tels que des coûts de réclamation au titre de la garantie en raison de l'envoi d'unités défectueuses aux clients et des coûts de remise en état résultant d'une prédiction selon laquelle une bonne pièce est défectueuse et du gaspillage d'efforts d'essais supplémentaires sur les pièces défectueuses. En outre, les deux procédés sont configurés pour développer au maximum la probabilité de détection de problèmes dangereux tout en permettant la régulation du taux de fausses alertes.
