A group supervisory control system is designed to perform efficient operation of multiple elevators, and its most basic function is to assign an appropriate elevator to a given hall-call.In this paper, in order to improve elevator group control perfomance, we propose a new system which includes experts' knowledge in fuzzy rule-base.In this system, when a new hall-call is generated, the rule which is adequate to the current traffic situation is selected. The elevator to be assigned to the hall-call is determined by the procedure written in the selected rule's conclusion part.An example of computer simulation is shown to ascertain the efficiency of this system.
