Design and implementation of FEGCS: fuzzy elevator group control system

The elevator group control systems (EGCS) are the control systems that manage systematically three or more elevators in order to efficiently transport the passengers. Most of the EGCS's have used the hall call assignment method to assign elevators in response to passenger's calls. This paper proposes a control strategy generation method, a hall call assignment method based on fuzzy theory and the fuzzy elevator group control system (FEGCS). The control strategy of FEGCS is made using the classification of the passenger traffic and system manager's requirements, and the hall calls are assigned to suitable elevators by the generated control strategy. The system is operated using the given control strategy which is defined by the system manager. The proposed system shows better results than the conventional methods in simulations, and the developed system is under the commercialization by an industrial company.
