153Mixture Designs to Optimize Pollution Level and Temperature of Fuels
Select “Temperature” for “Responses” and click on “Terms”. This opens the
dialog box shown in Figure9.38. Choose “Quadratic” for “Include component
terms for model” and choose the “Selected Terms” as shown in Figure9.38.
Click on “OK” and it takes you back to the dialog box shown in Figure9.37.
Click on “OK” and the output shown in Figure9.39 is the result. Notice that
all the P-values in Figure9.39 are less than 0.05, and hence this model in
Figure9.39 can be considered now for optimization. For optimization of tem-
perature, select “Response Optimizer” as shown in Figure 9.40. Doing so
opens the dialog box shown in Figure9.41. Move the “Temperature” column
from “Available” to “Selected”, as shown in Figure9.42. Click on “Setup” and
Entry of lower and upper bounds for components of fuel Zeo.
Unchecking “Randomize runs” box for fuel Zeo.
