Improving the perfomance of elevator systems using exact reoptimization algorithms

pdf-format:


Abstract

The task of an elevator control is to schedule the elevators of a
group such that small average and maximal waiting and travel
times for the passengers are obtained. We present a novel exact
reoptimization algorithm for this problem. A reoptimization
algorithm computes a new optimal schedule for the elevator group
each time a new passenger arrives. Our algorithm uses column
generation techniques and is, to the best of our knowledge, the
first exact reoptimization algorithm for a group of elevators. We
use our algorithm to compare the potential performance that can
be achieved for conventional (ie up/down buttons) and two
variants of destination call systems, where a passenger enters
his destination floor when calling an elevator. This research is part
of an ongoing project with our industry partner Kollmorgen Steuerungstechnik.
