An analysis of the structure of the kinetic scales of collision processes in rarefied multicomponent systems suggests the possibility of developing structural numerical models that would provide high flexibility and efficiency when implemented on state-of-the-art computers. In particular, it is shown that, by elaborating the kinetic scale structure, as the kinetic system approaches the state of thermal equilibrium or the steady state, it is possible to increase the speed of Monte Carlo algorithms in the numerical analysis of collision process kinetics. A stochastic structural model and results of calculations are presented.
