Planet formation models have been developed during the last years in order to try to reproduce and predict observations of the solar system and extrasolar planets. Using a modular planetary system formation model combining an extended core-accretion model including migration and disc evolution with an N-Body part for the dynamical interactions we perform population synthesis calculations in order to investigate the effects of different parameters for both the planetesimal and the gas disc and the competition and gravitational interactions of more than one planet forming in the same protoplanetary disc. We show the modification of masses, semi-major axes, period-ratios and general layout and stability of the resulting planetary systems varying the viscosity, irradiation by the star and the location and size of a dead zone.
