Thanks for writing back, sorry if my tone wasn't great before. > optimization was no good because the schedules it gave were "too tight". This matches fairly well with my experience -- getting a good objective function can be half the battle. A lot of people don't know what they want well enough to tell you. > Mostly people in business just do NOT want anything technical Well, in competitive markets it'll eventually be "do or die", and for common enough problems it doesn't need to be done in-house. I agree that businesses are (typically) very conservative about this sort of thing, but if there's value to be had by wringing efficiencies out of operations, Uber and Amazon will do it.
