  The intranuclear cascade model overestimates the multiplicity of produced
mesons in nucleus-nucleus interactions without taking into account meson and
baryon resonance production. Inclusion of the resonances leads to decreasing
multiplicity of mesons, neutrons and protons. In order to overcome the problem,
it is proposed to use the FRITIOF model adapted to low energies in a
combination with the reggeon theory inspired model of nuclear destruction. It
is shown that the combination allows one to reproduce satisfactory the meson
and baryon yields in the nucleus-nucleus collisions at the energy of 3.3
GeV/nucleon. The combined model works faster than typical quantum molecular
dynamic model, and allows one to estimate the data needed for creation of
electro-nuclear amplifier.
