1. A method for optimizing production of a film product on a film extrusion line, the method comprising:
acquiring, during operation of the film extrusion line, model parameters related to the production of the film product, wherein said model parameters include one or more of:
at least two input model parameters comprising raw material parameters, and
at least two output model parameters comprising film product parameters;
forming a parameter relationship between the acquired model parameters using a production model specific to the film extrusion line;
prioritizing at least one model parameter of the production model for optimization; and
modifying at least one non-prioritized model parameter of the production model based on the formed parameter relationship to optimize the prioritized model parameter;
optimizing the prioritized model parameter using the optimization target or the optimization direction specified; and
using the optimized model parameter in a production of the film product on the film extrusion line;
wherein at least an optimization target or an optimization direction is specified in the prioritization of the at least one model parameter.
