2.5 Sensitivity Automation Batch Mode, up to this point, has accomplished all of the objectives except for one. It has the ability to create multiple CONDUIT problems and modify every parameter of a problem that could be modified by a user. It has the ability to automatically run the multiple cases, and incorporates the means to quickly and effectively view the results of these problems. The only objective lacking is the ability to run the problems in such a way as to minimize user intervention. When running a CONDUIT problem, sometimes the optimization can get stuck. The user must then run a sensitivity analysis, freeze insensitive and correlated parameters, and continue. While this is not necessary for some cases, the same can’t be said for all cases. Thus, considering the large number of cases that could be used in a Batch Problem, some automation of this process had to be implemented, and so the Sensitivity Automation was created. 2.5.1 Typical Use of Sensitivity Tools Before the development of the Sensitivity Automation can be discussed, the details of the Sensitivity Analysis must be explained, with emphasis on the actions performed by the user. When an optimization ends, it lists a reason why. Depending on this reason, the user may opt to either accept the results and quit, or run a sensitivity analysis. Typically, unless the message indicates that the problem is fully optimized, the user would usually run a sensitivity analysis. The first step in a Sensitivity Analysis is the selection of the design parameters for the gradient calculation. Typically, the parameter selection would reflect the non-frozen parameters of the problem. However, 71
the user may choose to freeze additional parameters for other reasons. The gradient is then calculated, from which the insensitivities and correlations can later be determined. The user then chooses the specs to be used in the insensitivity calculation, and narrows down the design parameter selection even further, if necessary. The specs to be used in the insensitivity calculation are chosen based on their constraint type, and the current phase. In Phase 1, the optimization routine is looking only at the hard constraints. Thus, if any problems exist, they are due to the hard constraints and so they must be used. In Phase 2, the soft constraints are likewise critical and should be used, while the objective specs are to be used in Phase 3. The insensitivity plot is then created, shown in Figure 40.
