“…As the elevator group control system is a complex nonlinear dynamic discrete system, the waiting time, taking time for an elevator, energy loss and other factors as the control objectives, the control system are all very large. In order to shorten people's waiting time, take the time for an elevator, to reduce energy loss, the shortest waiting time, shortest distance, genetic algorithms, fuzzy control, a variety of elevator group control scheduling method [2,3], but now some elevator control technology there are still shortcomings and deficiencies. The advanced technology used in elevator group control system to further improve the operating efficiency of the existing elevator system to meet passengers' demand, further research is still required.…”
