We present numerical simulations of the system of open clusters of the Milky Way, whose aim is to provide constraints on the evolution of the star formation rate and the metallicity of the galactic disk. We find that the properties of the open cluster system are well described assuming an almost constant SFR for the disk, a primordial radial metallicity gradient which remains the same at all times, and the inexistence of an age-metallicity relationship.
