  We present a set of 144 galactic chemical evolution models applied to a Milky
Way analogue, computed using four sets of low and intermediate star
nucleosynthetic yields, six massive star yield compilations, and six functional
forms for the initial mass function. The integrated or true yields for each
combination are derived. A comparison is made between a grid of multiphase
chemical evolution models computed with these yield combinations and empirical
data drawn from the Milky Way's disc, including the solar neighbourhood. By
means of a chi2 methodology, applied to the results of these multiphase models,
the best combination of stellar yields and initial mass function capable of
reproducing these observations is identified.
