The general assumptions of the quasiparticle-phonon model of complex nuclei are given. The choice of the model Hamiltonian as an average field and residual forces is discussed. The phonon description and quasiparticlephonon interaction are presented. The system of basic equations and their approximate solutions are obtained. The approximation is chosen so as to obtain the most correct description of few-quasiparticle components rather than of the whole wave function. The method of strength functions is presented, which plays a decisive role in the practical realization of the quasiparticle-phonon model for the description of some properties of complex nuclei. It is shown that the quasiparticle-phonon nuclear model can be applied to the few-quasiparticle components of the wave functions at low, intermediate, and high excitation energies averaged in certain energy intervals.
