Knowledge-based elevator controller

Abstract

The traditional methods of controlling elevators in modern buildings are inaccurate and fall far short of the standard expected in large modern buildings where the control system must cope not only with peak demands but also with changing traffic patterns over the life time of the building. This paper describes the design and performance of a knowledge-based elevator control system that uses rules to compare possible movements and select the optimum route to maximise passenger transportation and minimise waiting time.
