Method and system for operating technical installation using artificial intelligence-based model

A computer-implemented method for operating a technical installation with an artificial intelligence-based model, comprising the steps of: a) detecting a first operating parameter of a reference device of the same construction as the technical installation in the form of a time-discrete first sensor signal by means of a first measuring means in a first operating environment and a first permitted operating mode, b) detecting a second operating parameter of the reference device in the form of a time-discrete second sensor signal by means of a second measuring means in a second operating environment and a second permitted operating mode, c) performing a first Fourier transform of the first sensor signal and a second Fourier transform of the second sensor signal, d) determining a quotient of the first Fourier transform and the second Fourier transform as a transfer function, e) generating and training an artificial intelligence-based first model for the reference device in the first operating environment, f) gene
