Abstract: The dispatching method of elevator group control System (EUCS) is a complicated optimization problem with multi-input and multi-output and it belongs to NP hard ctuestion. In order to solve the dispatching method of EUCS, a new strategy is proposed based of particle swarm optimization in this paper. Each particle stands for a dispatching scheme. Some solutions will be initialized at first, then the dispatching method is optimized in the direction of the shortest average passenger waiting time, ride time and the consumption of elevator energy. The comparative simulation resups show the effective of this algorithm.
