Abstract:
A method for optimizing a machine set-point utilizing a machine model which predicts the properties of the output product of the machine, while the machine operation is solely dedicated to the method for optimizing the machine set-point and is not operating for production, comprising:a. defining allowed ranges for the properties of the output product, the ranges of the possible machine set-points and optimal set-point criteria; b. carrying out calibration of the model of the machine for finding updated constants for the machine model; c. using the updated constants in the machine model, finding all set-points that will provide a product whose properties are within the allowed ranges; d. carrying out an optimization procedure to find from all the set-points found in step c, one optimized set-point; e. operating the machine at the optimized set-point found in step d, and obtaining a new output product; f. comparing the properties of the new output product to the allowed ranges; g. if the properties of the output product are within allowed ranges, the new set-point is found, and the procedure is successfully finished; h. if the properties of the output product are out of said allowed ranges, repeating the procedure from step b.
