Click the Prediction Profiler red triangle menu and select Optimization and Desirability > Maximize Desirability.
Figure 10.8 Prediction Profiler for Bounce Data.jmp with Desirability Maximized
When you maximize the desirability function, JMP identifies one combination of factor level settings (usually out of many possible combinations) that results in a predicted Stretch of 450. Figure 10.8 shows these settings as Silica = 1.069, Sulfur = 1.972, and Silane = 40.000. Next, you use the Contour Profiler to identify other points that maximize the desirability function.
Click the Response Stretch red triangle menu and select Factor Profiling > Contour Profiler. Suppose that you want to achieve your target while setting Sulfur to the value 2.0. Also, you want to make sure that the settings that you choose for Silane and Silica maintain predicted Stretch within 5 units of 450.
Figure 10.9 Contour Profiler for Bounce Data.jmp
The plot shows the contour of values of Silane and Silica for Stretch at 425 and Sulfur at 2.3.
Set the Current X for Sulfur to 2.
Set the Contour for Stretch to 450.
Set the Lo Limit and Hi Limit for Stretch to 445 and 455, respectively. Press Enter.
Figure 10.10 Contour Profiler Showing Optimal Settings for Silica and Silane
The unshaded band of Silica and Silane values gives predicted Stretch between 445 and 455 when Sulfur is set at 2.0. The values on the solid red curve give predicted Stretch of 450.
Drag the crosshairs that appear in the plot to the unshaded band to find settings for Silica and Silane that are best for your process from a practical perspective.
Suppose that your process is known to be more robust at low levels of Silane than at high levels. Then you might consider the settings in Figure 10.11.
Figure 10.11 Contour Profiler Showing Specific Settings for Silica and Silane
For Sulfur = 2.0, the factor settings identified by the crosshairs are Silica = 1.045 and Silane = 41.71. These settings are shown under Current X. At these settings, the predicted Stretch is 449.62071, shown next to Current Y.
