We have shown that the lattice-gas model with four repulsive pair interaction constants (corresponding to the four nearest coordination shells) on a simple cubic lattice is a sufficient model to describe the main types of cation ordering in relaxors. The phase diagram, obtained by the cluster variation method, shows the sequences of transitions between the phases 1:2 -->1:1 --> disordered and 1:2 --> disordered.
