Genetic algorithm for scheduling double different size crane system with different truck ready times

In order to improve the competitiveness of the container terminal, how to reduce the truck waiting time is the key point. In this paper, the optimization of double different size crane (DDSC) system with different truck ready time is studied. Firstly, a mathematical model for the minimum of truck waiting time is established. Then, genetic algorithm is designed to formulate an optimum DDSC scheduling scheme solving the interference between big crane and small crane. Finally, the results are analyzed and the numerical results show that the proposed method can quickly obtain an optimal solution of the problem.
