12Robust Parameter Design and Process Robustness Studies
Example 12.1 Two Controllable Variables and One Noise Variable
Example 12.2 Two Controllable Variables and Three Noise Variables
The response surface methods introduced in Chapter 11 provide the ability to optimize factor settings in order to produce a mean response that falls within specified limits. These tools may also be used to select factor levels that minimize the variation in the response due to factors that cannot be easily controlled during normal operation of the process. When you control these noise factors during the execution of a process robustness study, you can determine how the inevitable fluctuations in these factors (in the normal operation of the process) will affect ...
