power analysis / sample sizes for factorial designs

#1
Greetings,

I'm interested in calculating the power (or sample sizes required for a power) for factorial designs. As an example, if I have a 3-factor, 2-level design with 3 center points (11 runs total), and I know the difference in the response and the standard deviation of the experiments, how do I calculate power?

If you could point me to some articles and/or books that discuss this in particular, I would appreciate it.

Also, does anyone know if this is possible to do in JMP version 6? (main question will be posted in software forum)

Thanks,
Brian

Just as a followup, I found this paper that (apparently) discusses exactly what I'm looking for:

However, if anyone knows of anything simpler, or with more examples, please let me know. This paper looks like it will take a while to digest.
