Abstract： Aiming at the computational complexity，hardware high requirements of elevator intelligent group control scheduling algorithm，for meeting the needs of low-performance controller，the low computational complexity，easy to implement dual-mode group control scheduling algorithm was proposed. Depending on the traffic control mode decision cycle，the control mode was divided into energy consumption priority and minimum wait time control mode. Energy consumption priority mode scheduling algorithm was the target of energy saving，taking into account the elevator operating frequency balance and passengers by ladder congestion level. Minimum waiting time control mode was in order to minimize latency target，which using the equivalent time method to calculate the best call distribution elevator. The algorithm was evaluated in uplink peak，idle，random layer and down link peak traffic flow pattern. The result indicates that the algorithm can meet the demand for elevator group control and provide a solution for the low-end of elevator group control places.
