In spite of the recent progress in both theoretical and experimental studies of QCD, many aspects of multiple parton interactions (MPI) still require a detail investigation. In particular, double parton scattering (DPS) processes can play a dominant role for some specific kinematic regions of multi-jet production, especially in proton-nucleus (pA) collisions where the total DPS cross section is approximately ∌3A times bigger than the corresponding total DPS cross section in proton-proton (pp) collisions.

In this talk, I will provide a general overview of the state-of-the-art of the ``first principles''  and Monte Carlo description of DPS (MPI) processes with a special emphasize  on the  four-jet DPS production in pp and pA collisions and different approaches to model double parton distribution functions.
