For optimizing a production plant an objective function, "optimum criterion", was formulated and an optimum criterion of a part of the plant, an apparatus, consistent with that of the plant was proposed. This was specified for a counter-current extraction column with mechanical agitation and various sets of constraints were discussed. An optimization algorithm of complex system based on alternating minimization of individual parts and of the whole system was suggested.
