A Wigner-function approach to the study of quantum transport in open systems in presence of phonon scattering is presented. Two important issues will be discussed in the paper: a) the existence of Wigner paths in phase space with many analogies with the semiclassical description of transport and b) how to deal with boundary conditions for the analysis of real open structures. Theoretical and computational results will be discussed in view of the application of this formalism to the simulation of transport in mesoscopic structures.
