A (possibly untrue) story I heard about rolling racking: A multinational truck/earthmover manufacturer set up a parts depot in the UK a few years ago. They wanted it to be a real showcase, so they used rolling racking, 20 feet high, 75 feet deep. It was set up in a building that was the same width as the racks all pushed together plus one aisle. The racks were motorised, and a single computer-controlled fork truck could just fit in the single aisle, so the computer moved the racking so that the aisle was where the fork truck needed to be. The main computer had full control over where items were stacked, and could optimise the truck's route as well as the rolling racking for multiple picks, so whne something needed to be placed on a rack it went wherever was most convenient for the truck. Because of the acceleration needed to raise and lower the forks, as well as to move the truck out of the aisle so the racking could roll, they had a specially-wound high-speed motor made to raise and lower the forks. Just in case, they had a spare motor made. When the inevitable motor failure happened, management congratulated themselves on ordering a spare, but then they wondered where it was... only the computer knew. After some clever software work to find the location of the spare motor - it was in the third rack from the outer wall of the building, but they couldn't get to it because the truck was stuck in the only aisle, several racks away so the racks couldn't be rolled. Apparently to get to the spare motor they had to cut a hole in the building wall and tunnel through the intervening racks...
