Аннотация:Hadronic interaction models at cosmic ray (CR) energies are inherently uncertain due to the lack of a
fundamental theoretical description of soft hadronic and nuclear interactions and the large extrapolation
required from collider energies to the range of the most energetic cosmic rays observed (> 1020 eV). Model
uncertainties are evaluated within the QGSJET-II model, by varying some of the crucial parameters in
the limits allowed by collider data, and between QGSJET-II and other models commonly used in air
shower simulations. The crucial parameters relate to hard processes, string fragmentation, diffraction
and baryon production. Results on inelastic cross sections, on secondary particle production and on the
properties of air showers measured by ground detectors from energies of 1012 to 1019 eV are presented.
