Genetic algorithms are mainly useful for function optimization 
problems, I think.

This problem is really perfect for an expert system because it's, well, 
an expert system. :-) A bunch of heuristics, rules-of-thumb, which when 
you apply them to set of data set it outputs some recommendations 
recommendations. Stuff like  "If you employ spatula repair persons, 
then you get a spatula repair bay. If the facility is in a snowy clime, 
you get an indoor spatula repair bay with kitchenette. If not in a 
snowy clime, you get an outdoor spatula repair bay. You get a small,
