Define the robust design scenario<br />
Sparse<br />
Assumptions about<br />
effect sparsity<br />
Dense<br />
Yes<br />
Is the directionality <strong>of</strong><br />
noise factors known<br />
No<br />
Use fractional/full<br />
factorial array as<br />
outer array (instead<br />
<strong>of</strong> compound<br />
noise)<br />
Use compound noise<br />
(as defined by Taguchi,<br />
Phadke) as outer array<br />
Use random<br />
compound noise<br />
as outer array<br />
Carry out robust design using the<br />
chosen outer array<br />
