The aim of this paper is the construction of a regular procedure combining the merits of the decoupling method and of the perturbation theory. A continuous iterative procedure is invented for calculating observable quantities, and the fast convergence conditions for this procedure are shown to be equivalent to the fixed-point conditions when the Gell-Mann-Low function is nullified. The construction of a procedure gives the possibility of finding subsequent corrections for any initial approximation.
