Screening: SB
Example: supply chain; 92 factors; 10 factors remain
after 19 simulated input combinations
Procedure (also see previous Figure):
•
Aggregate factors into groups
•
Experiment (simulate) with group factors
•
Split important groups; ignore unimportant
SB assumptions:
•
1st-order polynomial & two-factor interactions
•
Known positive signs: no canceling out
•
‘Strong heredity’: b(j) = 0 → b(j, j’) = 0
