Claim:
1. A method for operating a continuous annealing line for processing a rolled steel strip, comprising: using a measuring device to measure a property of the rolled steel strip, supplying the property of the rolled steel strip as an input variable to a computer-aided model of a control device, the property of the rolled steel strip being possessed by a section of the rolled steel strip located upstream from or in the continuous annealing line, using the computer-aided model and the property of the rolled steel strip to predict a material property of the rolled steel strip after the continuous annealing line and to produce a predicted material property, comparing the predicted material property with a predetermined target value, annealing the rolled steel strip with the continuous annealing line, and if the predicted material property deviates from the target value, altering a process variable of the continuous annealing line while the section of the rolled steel strip is located upstream of or in the continuous annealing line, wherein the computer-aided model performs model-predictive regulation of the continuous annealing line using a model parameter, the material property that is predicted is measured after the continuous annealing line to produce a measured material property, and if the predicted material property deviates from the measured material property, the model parameter is adapted.
