 Re: an optimal elevator-use algorithm Alan Balkany 13-Sep-12 4:41
 I've thought about this problem (while waiting for elevators!).   A few random comments: The standard algorithms used by existing elevators seem to be non-optimal; A cluster of floors where an elevator has been requested will slow down multiple elevators making everyone wait unnecessarily. This is because when the first elevator stops at the first floor in the cluster, the remaining elevators will get bogged down by the next floors in the cluster.   It would be more optimal for a single elevator to handle the cluster, while the others continue down with no delays.   It's hard to optimize for the number of people, because there's no way of knowing exactly how many people are on a particular elevator. We can make a guess, however. When an elevator stops at a requested floor, we can assume at least one person got on. But we don't know how many got off.   Using artificial intelligence may optimize the algorithm better than any "blind" approach, that doesn't take historical use patterns into account.
