During the last few years great observational advances have allowed us to study and characterize exoplanets in different kinds of planetary systems. From a theoretical point of view, population synthesis models are the ones that allow us to find a relationship between the observed diversity of planetary systems and the properties of the protoplanetary disks from which they are formed. To find such correlations within the framework of the planetary science is a necessary challenge. In this work, we present a new numerical code called PlanetaLP338 , which is able to build a wide diversity of planetary systems during the gaseous phase. This numerical model describes the evolution of planetary embryos and planetesimals while the gaseous component is still present in the system. This numerical algorithm analyses the evolution of a given system from parameters such as mass and metallicity of the star, mass of the protoplanetary disk, gas and solid surface density profiles, planetesimal size, and dissipation time of the gaseous component. Moreover, our semi-analytical code incorporates some important physical phenomena of planetary formation like type I and type II migration, gas accretion, water delivery in embryos and planetesimals, and the treatment of the fusion between embryos considering their atmospheres. The main goal of the present work is to analyze the different kinds of resulting systems and to find correlations between the properties of the disks and the planetary systems formed in our simulations. These planetary systems will be then analyzed statistically exploring which are the range of different parameters that provide systems similar to our own.This investigation will allows us to improve our knowledge concerning the formation of planetary systems analogous to our Solar System.
