Abstract
(DE)
Es ist ein Verfahren zum Betreiben einer Vorrichtung zur Her Stellung eines Produktes beschreiben, welches die folgenden Schritte umfasst: - Erfassen von zumindest einem Qualitätsdatensatz (10, 10') umfassend Messwerte eines oder mehrerer Qualitätsparameter, die je einer Eigenschaft des Produktes entsprechen; - Erfassen von zumindest einem zugehörigen Maschinendatensatz (20, 20') umfassend Realwerte von mehreren einstellbaren Maschinenparametern der Vorrichtung; - zeitliches Zuordnen des Qualitätsdatensatzes (10, 10') zum Maschinendatensatz (20, 20')und Generieren eines ersten Datensatzes (30) umfassend zeitlich korrelierte Messwerte und Realwerte; - mindestens einmaliges Wiederholen der vorangegangenen Schritte zum Generieren wenigstens eines zweiten Datensatzes (30'); - Bestimmen einer Korrelation (40) zwischen dem oder den Qualitätsparametern und den Maschinenparametern durch Vergleich der erfassten Datensätze (30, 30') und Erstellung eines Steuerungs modells für die Vorrichtung, - Bereitstellen eines entsprechenden Sollwertes für zumindest einen der einstellbaren Maschinenparameter anhand des Steuerungsmodells, ausgehend von einem Sollwert des oder der Qualitätsparameter. Es ist auch ein Computerprogrammprodukt zur Durchführung des Verfahrens und eine Vorrichtung umfassend dieses Computerprogrammprodukt beschrieben.

The invention relates to a method for operating a device for producing a product, comprising the following steps: - capturing at least one quality data record (10, 10') comprising measured values of one or more quality parameters, each corresponding to one property of the product; - capturing at least one associated machine data record (20, 20') comprising actual values of a plurality of adjustable machine parameters of the device; - chronologically assigning the quality data record (10, 10') to the machine data record (20, 20') and generating a first data record (30) comprising chronologically correlated measured values and actual values; - repeating the preceding steps at least once to generate at least one second data record (30'); - determining a correlation (40) between the quality parameter(s) and the machine parameters by comparing the captured data records (30, 30') and creating a control model for the device, - providing a corresponding target value for at least one of the adjustable machine parameters on the basis of the control model, proceeding from a target value of the quality parameter(s). The invention also relates to a computer program product for carrying out the method and to a device comprising said computer program product.

L'invention concerne un procédé destiné au fonctionnement d'un dispositif destiné à la fabrication d'un produit, qui comprend les étapes suivantes : - enregistrement d'au moins un ensemble de données de qualité (10, 10') comprenant des valeurs de mesure d'un ou de plusieurs paramètres de qualité qui correspondent chacun à une propriété du produit ; - enregistrement d'au moins un ensemble de données de machine associé (20, 20') comprenant des valeurs réelles de plusieurs paramètres de machine réglables du dispositif ; - attribution dans le temps de l'ensemble de données de qualité (10, 10') à l'ensemble de données de machine (20, 20') et génération d'un premier ensemble de données (30) comprenant des valeurs de mesure et des valeurs réelles corrélées dans le temps ; - répétition des étapes précédentes au moins une fois pour générer au moins un second ensemble de données (30') ; - détermination d'une corrélation (40) entre le ou les paramètres de qualité et les paramètres de machine en comparant les ensembles de données enregistrés (30, 30') et en créant un modèle de commande pour le dispositif, - mise à disposition d'une valeur de consigne correspondante pour au moins l'un des paramètres de machine réglables à l'aide du modèle de commande, sur la base d'une valeur de consigne du ou des paramètres de qualité. L'invention concerne en outre un produit programme informatique destiné à mettre en œuvre le procédé et un dispositif comprenant ledit produit programme informatique.
