An approach to re-summation of enhanced Pomeron graphs is proposed. The latter is applied to develop a new Monte Carlo model which treats non-linear interaction effects explicitely in individual hadronic collisions. On the other hand, we discuss a possible generalization of the scheme, which allows to account also for pQCD effects. In particular, this offers a possibility to fix model parameters on the basis of data on hadron-hadron cross sections, hadronic multi-particle production, and on total and diffractive proton structure functions.Prepared for XXXXth Rencontres de Moriond on QCD and High Energy Hadronic Interactions, March 12-19 2005, La Thuile, ItalyHigh Energy Physics - PhenomenologyEnhanced Diagrams in High Energy Hadronic and Nuclear Scatteringtext
