Graphical Optimization When you did the numerical optimization, you found an area of satisfactory solutions at a temperature of 90 degrees. To see a broader operating window, click on the Graphical node. The requirements are essentially the same as in the numerical optimization: • 80 < Conversion • POE(Conversion) < 5 • 60 < Activity < 66 For Conversion, which comes up by default, enter 80 for the Lower Limit. You do not need to enter a high limit for the graphical optimization to work. Completed Screen for Graphical Optimization: Conversion Click on the response for POE(Conversion). Enter 5 for the Upper Limit. Finally, click on the response of Activity. Enter 60 for the Lower Limit and 66 for the Upper Limit. Then click on the Graphs button to produce the “overlay” plot. Notice that regions not meeting your specifications are shaded out, leaving (hopefully!) an operating window or “sweet spot.” 6-38 • Response Surface Method (RSM) Tutorials Design-Expert 6 User’s Guide
Overlay Plot Rev. 3/12/01 To match the numerical optimization, go to the Factors tool, right click on catalyst and select it for the Y-axis. Then press the Sheet option and set temperature as a constant Value at 90. Sheet Mode to Set Constant for Temperature Design-Expert now overlays response contours for each response. Click on the Gauges option to make the Factors Tool less obtrusive. Now you can search for a “compromise” optimum - windows of operability where requirements simultaneously meet the critical properties.
