The general principles of the choice of the reduced description parameters of nonequilibrium states γα(t) and the construction of the nonequilibrium statistical operator (NSO) ρ(t) are discussed. On the basis of Kavasaki - Gunton projection operator an explicit non-Markov form of NSO with respect to parameters is obtained and the equivalence of the method to the other methods using boundary conditions for ρ(t) or "mixing" operator is shown. An exact NSO transformation to γα(t) Markov form with respect to γα(t) at arbitrary dependence of Vt perturbation on time is made. The generalized kinetic equations not containing the memory with respect to γα(t) are obtained being convenient for practical application.
