Dynamic Fuzzy Logic Elevator Group Control System With Relative Waiting Time Consideration

High-rise buildings with a considerable number of elevators represent a major logistical problem concerning saving space and time for economic reasons. For this reason, complex elevator group control systems (EGCSs) are developed in order to manage elevators properly. In this paper, the first entirely dynamic fuzzy logic EGCS to dispatch landing calls so as to minimize waiting time is proposed. The fuzzy logic design described here not only constitutes an innovative solution that outperforms usual dispatchers but also an easy, cheap, feasible, and reliable solution, which is able to be implemented. This is achieved by an intelligent design that joins together the simplicity of fuzzy design with the performance of the most sophisticated controllers by considering the impact of landing call reallocations within the system waiting time scale based on the assessment of the landing call relative/absolute waiting time balancing.
