Lruns(Levels^Factors) or Ln(s^k): Orthogonal array of N runs where k factors take on any value from a set of s symbols/level.
The borders and shading dialog box :
5 x 5 x 9 x 9 = 2025 combinations!
L81(94) array will suffice
3 x 3 x 3 x 2 x 2 = 108 combinations!
OATS could be applied in:
1- R Krishnan, S Murali Krishna, P Siva Nandhan - Motorola: Combinatorial Testing: Learnings from our Experience .
2-Madhav S. Phadke , Quality Engineering Using Robust Design.
