  A short review of simulation results of anti-proton-proton and
anti-proton-nucleus interactions within the framework of Geant4 FTF (Fritiof)
model is presented. The model uses the main assumptions of the
Quark-Gluon-String Model or Dual Parton Model. The model assumes production and
fragmentation of quark-anti-quark and diquark-anti-diquark strings in the
mentioned interactions. Key ingredients of the model are cross sections of
string creation processes and an usage of the LUND string fragmentation
algorithm. They allow one to satisfactory describe a large set of experimental
data, especially, a strange particle production, Lambda hyperons and K mesons.
