Intelligent Algorithm of Elevator Group Control by Statistic Approximation

In this paper, a group control intelligent algorithm for elevator systems is proposed. Since the elevator group control can viewed as a combination of on-line scheduling, uncertain, multi-objective and stochastic optimization problem, hall call waiting time (HCWT) are estimated by statistic approximation of traffic data based on the real traffic situations .The fitness of each elevator servicing the hall call is deduced based on the HCWT using fuzzy set theory, so the elevator is dispatched optimally. The results of computer simulation show the effectiveness of the proposed algorithm.
