Replication of fractional factorial

We are performing a fractional factorial DOE experiment for robustness of our system. The factor combinations will be replicated three times.

How should I think about replication in contrast to different operators? Same operator for all three replicate of same factor combination or splitting the replicate out to different operators?

Any thoughts? Thank you,

Maria

Operator should be considered a "block" variable, in DOE terminology.

Thus, when you have JMP create the fractional factorial, you select a fractional factorial with the proper number of blocks (operators).
