In this paper a multi objective strategy based on
GAS with ad hoc operators is presented. With the help of
two different examples it will be shown that multi objective
Pareto design can be addressed with GA and that even a
better understanding of the design problem can be achieved
by means of this approach.
The first case consider a multi-point pressure reconstruc-
tion problem of an isolated airfoil that should represent a
compromise between a high lift airfoil in subsonie regime
and low drag airfoil in transonic conditions.
The second case consider the preliminary design ofan aero-
nautical gas turbine for which different mission specification
must be fulfilled.
