In this paper we take subsemilattice of X-semilattice of unions D which satisfies the following conditions:
We will investigate the properties of regular elements of the complete semigroup of binary relations B_x(D) satisfying V(D,а)=Q. For the case where X is a finite set we derive formulas by means of which we can calculate the numbers of regular elements and right units of the respective semigroup.
