Simulation of a Four-Car Elevator Operation Using MATLAB

Abstract

The design and simulation of a four-cars-elevator controller in a nine storey building is described in this paper. The design and simulation were accomplished using MATLAB TM fuzzy logic toolbox. The logic of the controller of a multi-car elevator has to be designed in such a way that the average waiting time is minimized while keeping the energy consumption of the system optimum. This is a multi-criteria optimization problem in stochastic environment and is best approached through Artificial Intelligent techniques. The work here focuses mainly on extracting the rules to minimize factors (i.e. waiting time, travelled distance and riding time) in order to minimize the energy consumed by the system. In this paper a detailed algorithm is presented to achieve the multiple objectives of minimizing the waiting time and the distance travelled simultaneously. This was accomplished by distributing different weightage to different quantities and then minimizing a combined cost. A simulator has been built with interactive GUI in Matlab to evaluate the efficacy of the algorithm.

Simulation Based Elevator Group Control System for Multi-Storey Building

“…In this elevator system, a twenty-digit keypad is installed in the hall of each floor where the passengers enter their destination floor before entering in the elevator car. When the destination was identified priory and no extra call can be assigned by the traveller while travelling within the elevator (Kim et al, 2000;King and Bouketir, 2008). This will provide almost entire and precise data of the current traffic situation and it will make the work of EGCS easy in dispatching the elevator for particular assigned information.…”

“…Simulation is a well-established tool for studying elevator traffic, particularly for traffic that is not uppeak traffic. 2,5,10–13 Such simulations may either be discrete event based or time-sliced.…”
