A new modeling method for elevator group control system with cellular automata

Aiming at elevator group control systems (EGCS), this paper proposes a new modeling method with cellular automata theory and builds a EGCS model which consists of three modules: group control module, elevator movement module and assignment sequence module. Different group control principles can be applied in the group control module. Elevator movement module simulates the moving behaviors of elevators by using cellular automata. Assignment sequence module is established to logically store call orders to every elevator. This model is simply structured and easy to modify. Computer simulations show that the proposed modeling method is creditable and the established EGCS model gives out satisfied performance. This modeling method can also be applied to other discrete event dynamic systems.
