  A set of programs for the numerical simulation of the diffusion decomposition
processes was developed by using simulation methods, kinetic and particle
method. The complex has been validated on the model system Ni-Al by the growth
of -phase separations. The results on the evolution of the distribution
function and other characteristics of the ensemble, which in the zero volume
fraction approximation are asymptotically in good agreement with the theory and
the experiment, have been obtained. The peculiarity of the created program
complex is the possibility of its adaptation to the description of the
decomposition of multicomponent multiphase systems
