The dual topological unitarization of hard and soft hadronic collisions is formulated as a Monte-Carlo event generator for events containing both the soft (low p{perpendicular}) and hard (jets, minijets) component of hadron production. The parameters of the model are determined from fits to the energy dependence of the total and inelastic hadron cross-sections and from the predictions of the QCD-parton model for the perturbative hard constituent scattering cross sections. The properties of the model are studied. Good agreement of the model predictions is found with data at present accelerator and collider energies. The predictions of the model for TeV colliders are presented. Interesting changes of the produced multiparticle system are formed when selecting classes of events with and without hard jets or minijets. 35 refs., 22 figs., 3 tabs.
