1. A method for automating a control or a regulation of a film extrusion line, comprising:
detecting at least two model parameters which are:
(a) input parameters of a production model for detecting a production situation of the film extrusion line, or
(b) output parameters of the production model for detecting a film product situation of the film extrusion line,
forming a parameter relationship between the at least two model parameters through the production model,
determining, based on the parameter relationship, at least one further model parameter in a form of a non-detected input parameter or a non-detected output parameter of the production model,
automating a control or a regulation of the film extrusion line using the at least one further model parameter,
wherein the model parameters in the form of input parameters are at least one of the following: raw material parameters, recipe parameters, plant parameters, machine parameters, and film parameters.
