Abstract: Up till now, the main target of elevator scheduling algorithms at home and abroad is minimization of passenger waiting time, which results in fewer passenger numbers and higher energy consumption during elevator operation in non-rush hour traffic. In order to balance the service efficiency and energy-saving of elevator, a new elevator scheduling rule for energy-saving based on elevator waiting-time is proposed. In order to quantitatively analyze the energy-saving effects of the new elevator scheduling rule based on the waiting-time, the new software is developed. The software can simulate elevator operation, calculate energy consumption and analyze energy-saving effected by generating randomly passenger flows, and then the amount of energy consumption, the elevator start and stop frequency and running distances are compared in different combined conditions of the height of building, the numbers of elevator, the elevator rated capacity, the concentration ratio of passenger in 5 min while different waiting-times are used and not used. The results of simulating tests show that the average energy-saving effects of 7.1%~9.4% can be gotten by using different waiting-time, and that introducing the elevator scheduling rule based on the waiting-time into the traditional elevator scheduling algorithms is a low-cost effective method of elevator energy-saving.
