[en] A Monte Carlo generator of Chou-Yang model to describe proton-proton soft scattering is developed based on pp NSD scattering data and the subtraction of the contribution due to hard scattering. This generator can be used for the description of soft hadronic NSD proton-proton interactions from 26 GeV to 22 TeV. Major experimental results observed on colliders are reproduced reasonably by using the generator combined with the calculation of large p_T jet production and hadronization. A decrease of inelasticity with the increase of energy is predicted
