Response Surface Optimization Tutorial This tutorial shows the use of Design-Expert software for optimization experiments. It's based on the data from the Response Surface Tutorial. You should go back to this section if you've not already completed it. For details on optimization, see the on-line program help. Also, Stat-Ease provides indepth training in its Response Surface Methods For Process Optimization workshop. Call or visit our web site for information on content and schedules. In this section, you will work with a three-factor central composite design on a chemical reaction. The factors are: time, temperature and catalyst. The experimenters measured two responses: yield and activity. You will optimize the process using models developed earlier in the Response Surface Tutorial. Start the program by finding and double clicking on the Design-Expert icon. You will find the case study data, with the responses already analyzed, stored in a file named Rsm-a.dx6. Use the File, Open Design menu to load the data file. The standard file open dialog box appears. File Open Dialog Box Once you have found the proper drive, directory and file name, click on Open to load the data. To see a description of the design status, click on the Status node. Drag the left border and open the window to see the report better. You can also re-size columns with the mouse. From the design status screen you can see that we modeled conversion with a quadratic model and activity with a linear model. 6-26 • Response Surface Method (RSM) Tutorials Design-Expert 6 User’s Guide
Design Status Screen Numerical Optimization Rev. 3/12/01 Design-Expert software’s numerical optimization will maximize, minimize or target: • A single response • A single response, subject to upper and/or lower boundaries on other responses • Combinations of two or more responses. We will lead you through the latter case: a multiple response optimization. Click on the Numerical node to start the process.
