written in FORTRAN (no joke here) (Score 1)

my bro-inlaw works for AB in St. louis. no joke
guess what some of the backend programs that
drive this system are written in?

Yeup.. FORTRAN.. takes inputs and parameters
from across the US, they all go into a huge model
which grinds throughout the week, and
spits out the optimal beer distro.

It's a queing theory geeks wet dream.. a very large
and classic IE problem that they crank through and
solve every week.

I cant recall the hardware that they use to run this
thing on.. I'll have to ask next time I see him.
