Robust Parameter <strong>Design</strong> and Process
Robustness Studies
• Origins <strong>of</strong> the RPD problem
• Taguchi and the American Supplier Institute
• RPD – proper choice <strong>of</strong> controllable factors to achieve
robustness, or insensitivity to changes in uncontrollable
noise variables
– Control factors
– Noise factors – these are factors that are uncontrollable in the
system but controllable for purposes <strong>of</strong> a test
• An RPD problem in a manufacturing process is <strong>of</strong>ten called
a process robustness study
