Figure 8. Comparison of Pareto front as obtained by the proposed and the conventional RDO approaches
tune the robustness of a solution through suitable
choice of this parameter. It can be clearly observed
from the figure that for a specific level of disper-
sion Δf, if the desired objective is to minimize the
weight of the frame, the proposed RDO approach
always yields lesser weight compared to the con-
ventional RDO approach. Furthermore, for a
prescribed weight of the frame, the dispersion of
the optimal weight Δf obtained by the proposed
RDO approach is also observed to be lesser than
that obtained by the conventional RDO approach.
To quantify the computational involvement of the
proposed RDO approach, the CPU time required
to generate the complete Pareto front by both the
approaches are computed. It is observed that the
proposed RDO approach needs 25 minutes
whereas the conventional RDO approach needs
40 minutes for this purpose. This clearly indicates
