Comparative features of the Cascade Model and the BUU model are presented and followed by a Quantum Theory Derivation of the Vlasov equation. Several modifications are made to the BUU model: the inclusion of a momentum-dependent potential instead of the usual Skyrme potential, the replacement of the "old" detailed balance cross section for delta reabsorption by the Danielewicz cross section, and a proper generation of the $ Delta$ mass, using a Monte-Carlo simulation. The effects of these ingredients on pion yields at beam kinetic energies in the range (0.4 AGeV-1.8 AGeV), and pion energy spectra at 90$ sp circ$ are analyzed. It is found that our numerical simulations agree quite well with experiments, except for pion energy spectra at low pion kinetic energies.
