abstract = "Optimization is now an established tool for obtaining better
solutions in engineering design. Nevertheless, the multiplicity of
possible applications and the continuing search for better
computational performance has motivated researchers in continuing
to propose new methods, as well as improvements on existing ones.
Not only optimization has allowed a better exploration of the
design space, it also can signifi cantly reduce the time of the
design process. In this paper the advantages of using a fully
multiobjective and multicase approach for the design of space
radiators is presented. The optimization of Amazonia-1 satellite
batteries panel thermal design is investigated. Instead of
conventional space radiators, in this work an innovative solution
considering the fi n as heat absorber is analyzed. The results
have shown that there are several viable confi gurations regarding
to fi n coating material, heater power consumption and additional
mass, and the choice of the appropriate radiator confi guration
shall be evaluated based on system impact. The possibility of
testing automatically different coatings and sizes for the fi n,
allowed by the optimization approach, increased signifi cantly the
probability of fi nding viable solutions on the design space.",
