1. A method for predicting process deviations in an industrial-method plant, the method comprising:
automatically generating a prediction model, wherein, for generating the prediction model, process values and/or status variables measured by a sensor are stored during operation of the industrial-method plant for a predetermined period, and wherein the predetermined period for which process values and/or status variables are stored during operation of the industrial-method plant is predetermined in dependence at least one of:
(i) the industrial-method plant is in an operation-ready state, in particular for a production operation, for at least 60% of the predetermined period,
(ii) the industrial-method plant is in a production-ready state for at least 60% of the predetermined period,
(iii) a predetermined number of process deviations and/or disruptions in the predetermined period; and
predicting process deviations during operation of the industrial-method plant, using the prediction model, wherein the method for predicting process deviations is carried out in an industrial supply air plant, a pre-treatment station, a station for cathodic dip coating and/or a drying station.
