Models of Galactic chemical evolution are nowadays able to reproduce the vast majority of the observed characteristics of our Galaxy and the models computed by our group are among the most successful ones. There are, however, a number of open questions on the evolution of the Galaxy, which still require further studies. Some of these issues are being examined in detail at the Bologna Observatory. In 1999, we have essentially concentrated on the feedback between stellar nucleosynthesis and chemical evolution (Tosi 2000a), on the evolution of the abundance gradients and on the cosmological application of Galactic chemical evolution models.
