Arrangement for regulating a given running criterion of an industrial installation on an optimum value corresponding to a known sense end of this criterion, as a function of a determined regulation parameter, constituted by a combination of devices operating in the course of sequences periodicals called optimization, which can be triggered by an operator, characterized in that this combination includes watchmaking devices that supply control pulses at certain moments in the course of each optimization sequence, measuring devices attached to the installation, which give at all times a measurement signal of the walking criterion, means controlled by the watchmaking devices that vary the regulation parameter of predetermined magnitudes at regular intervals, calculation means, controlled by the watchmaking devices, which integrate the measurement signal of the criterion during periods of fixed duration comprised between two successive modifications of the parameter, means of calculation linked to the precedents that give, each one, separations between two successive integrals, analysis devices that determine at regular intervals, according to these separations, the evolution of the criterion of march, regulation means, controlled by these analysis devices, which act on the devices for modifying the regulation parameter to ensure a next modification of this in a favorable sense to the evolution of the criterion towards its extreme, calculation devices triggered by the analysis devices, which elaborate an optimal value of the regulation parameter when the last measured separation indicates that the walking criterion is close to its end, the elaboration of this optimal value being carried out in relation to the last value of the parameter, representing the amplitude of this last modification and a func given, approximately, the variations of the criterion in the vicinity of the end, and stop devices, fired by these analysis devices, which block the clock devices until the next optimization sequence, when the regulation parameter is set on the value optimal found.
