Let RR be a commutative ring with identity. In this paper, a Cohen-type theorem for ww-Artinian modules is given, i.e. a ww-cofinitely generated RR-module MM is ww-Artinian if and only if (M/annM(P))w(M/annM(P))w is ww-cofinitely generated for every prime ww-ideal PP of RR. As a by-product of the proof, we also obtain a detailed representation of elements of a ww-module and the ww-theoretic version of the Chinese remainder theorem for both modules and rings.
