A process for continuously producing an elastomeric composition includes the step of dosing into at least one extruder at least one ingredient by means of a dosing device, wherein the dosing step is regulated on the basis of: i) actual weight values of the at least one ingredient measured at dosing instants of an evaluation time period of predetermined duration preceding a given dosing instant; ii) expected weight values of the at least one ingredient calculated for corresponding dosing instants of the evaluation time period of predetermined duration preceding the dosing instant; and iii) expected weight values of the at least one ingredient calculated for a prediction time period of predetermined duration following the dosing instant; so as to minimize a prediction weight error between actual weight values measured during the prediction time period and the expected weight values calculated for the prediction time period, and a model weight error between actual weight values measured during the prediction time period and theoretical weight values of the at least one ingredient corresponding to the target weight loss of the at least one ingredient.
