In this study, we develop a computationally efficient heuristic, called constant summation (CSUM), to minimize the total crane's working time required to retrieve all the containers from a given bay. Numerical results show that CSUM is very promising in dealing with the container retrieval problems and outperforms the best known approaches recently presented in the literature in terms of the crane's working time.
