The extended Hubbard model with on-site attraction and random infinite-range inter-site Coulomb interaction is stUdied for the arbitrary band filling. In the strong coupling regime the problem is mapped onto a system of hard-core bosons (local electron pairs) on a lattice described by the anisotropi
