Abstract: The present disclosure relates to an apparatus for producing containers which comprises: a control device which is designed to set at least one working parameter for the production of at least one first container, a measuring device that is designed to measure at least one container parameter of the at least one produced first container in order to obtain a measured value of the at least one container parameter, a measurement correction device designed to correct the measured value of the at least one container parameter based on at least one model parameter of a numerical model, and a performance parameter determination device that is designed to determine at least one performance parameter value on the basis of the corrected at least one measured value. The control device is designed to control the production of at least one second container based on the at least one working parameter.
