Early type galaxies constitute one of the largest populations inhabiting groups and clusters in the local Universe. Thus, their study might provide important clues to understand the process of formation and evolution of structures in the Universe. Results from a statistical analysis on this type of galaxies in numerical simulations within cosmological context will be presented. Integrated properties of such simulated systems will be analyzed at redshift z=0 in order to establish the main astrophysical processes which detetermine their evolution. The ability of models to reproduce observational results will be also tested.
