Resumen:
For several decades now, open clusters have been used to study the
structure and chemical evolution of the disk of our Galaxy. Due to the
fact that their ages and metallicities can be determined with relatively
good precision, and since they can be observed even at great distances,
they are excellent tracers of the variations in the abundance of heavy
chemical elements with age and position in the Galactic disk. In the
present work we analyze the star formation history and the chemical
evolution of the disk of the Galaxy using numerical simulations of the
dynamical evolution of the system of open clusters in the Milky Way.
Starting from hypotheses on the history of cluster formation and the
chemical enrichment of the disk, we model the present properties of the
Galactic open cluster system. The comparison of these models with the
observations allows us to examine the validity of the assumed hypotheses
and to improve our knowledge about the initial conditions of the
chemical evolution of the Galactic disk.
