To produce a mixture having properties specified by constraints, the flow rates (Qi) of the mixture components are controlled in such a way that the mixture achieves the specified properties and the flow rates (Qi) of the components deviate as little as possible from the specified values (Qdi). For this purpose, the set point values (Qoi) for the flow controls are calculated from the known Lagrange formula, the target function being the sum of the weighted squares of the deviations between set point value and specified values. The main area of application of the invention is gas mixing units. <IMAGE>
