We introduce a method for computing Hilbert decompositions (and consequently the Hilbert depth) of a finitely generated multigraded module $M$ over the polynomial ring $K[X_1, ldots, X_n]$ by reducing the problem to the computation of the finite set of Hilbert partitions. We show that Hilbert partitions may also be used for computing the Stanley depth of the module $M$. Thus, we provide solutions to some problems proposed by Jurgen Herzog.
