This paper focuses on the application of rigorous optimization methods
to the design of complete satellite structural subsystems. It discuss
es a software system being developed which is based on a combination o
f finite-element analysis using MSC/NASTEAN, numerical optimization, a
pproximation concepts, and object-oriented technology. The benefits of
object-oriented design, in the context of satellite structural optimi
zation, are identified. In addition, an approach to system optimizatio
n, including multilevel and coupled subsystem optimization is explored
. Finally, the application of this software to the actual design of tw
o satellite structures is presented.
