What the group control of the elevator traffic system deal with is a complex, random, multi-objective, nonlinear, uncertain decision-making problem. Good effect of controlling elevators can’t be achieved with traditional control methods. Elevator group control system based on fuzzy single chip computer is introduced in this paper. Fuzzy inference can be carried out based on control rules that are programmed based experts’ experience. Then elevators are allocated in the light of inference result in order to achieve ideal control effect.
