Elevator group control is one of the important issues in vertical transportation systems in
buildings. For an efficient group control algorithm it is required to overcome some optimization
problems. From the perspective of quality of service two fundamental parameters needed to be optimized
are waiting time and journey time. Elevator group control algorithms can be developed based on soft
computing methods used for optimization. In the last decade Genetic Algorithm(GA) has attracted
researchers’ attention as the suitability for the encoding car dispatching problem. In this study we
enhance a previous study suggested for optimization of waiting time. The proposed method reduces
average waiting time and uses a simpler encoding approach which results in efficiency in terms of
computational cost. We explicitly demonstrate the method on the referred scenario for the purpose of
visualization and insight
