6 Conclusions In the course of this paper, it has been shown that Batch Mode is an effective tool for use with multiple CONDUIT problems. Batch Mode provides the user with the capability of creating a large number of CONDUIT problems for optimization or evaluation. These problems can then be optimized or evaluated without intervention by the user. Batch Mode also provides the capability to analyze the results of a large number of optimized or evaluated cases in an efficient manner. It offers HQ Window thumbprint plots to check for robustness, along with gain schedule plots against user defined variables. The Sensitivity Tools of CONDUIT were automated for use with Batch Mode, giving the Run Mode the ability to automatically freeze insensitive or correlated parameters. Finally, it was shown that the simple logic of the correlation freezing was sufficient for the purposes of freezing correlated parameters. The optimization of the SH-2G demonstrated many of the features and capabilities of Batch Mode. First, it demonstrated the ease by which a Batch Mode problem could be created, optimized, and evaluated. The results of these cases were then used to show that smooth gain schedules could be obtained through the use of Batch Mode. Finally, the use of thumbprint plots to examine the robustness of a system were also shown to be effective. 127
