RESUMO

This work deals with implementing exchange and interchange algorithms. Efficiency based optimality criteria were used to and optimal fractional factorials for response surface designs. Both treatment choice and blocking were considered. Designs found for each situation were compared to alternatives from literature. In all cases A-optimal or D-optimal designs were more ecient than designs constructed using other methods like combinatorial considerations. Resolvable designs were also found and compared to a Steiner triple system for 15 treatments. Resulting algorithms are flexible and should be used by applied researchers as alternatives to fractional factorials. This is also valid for initial steps of research as well as for fitting response surfaces in optimization steps.
