Synchronized Loading and Unloading Containers Method Based on Simultaneous Hatches Operations

Abstract:

Based upon synchronized loading and unloading containers method, a multi-objective optimization model was established. Minimizing the weighing vehicle transporting time and quay-crane(QC) handling time is taken as the objective. When the container ship reached the terminal, loading and unloading work was beginning. The optimal operational sequence of hatches in a bay was obtained by optimized computing, as well as the shortest handling time of vehicle and quay-crane. By numerical simulation, the efficiency is improved 22.62%~31.47%; the average rate of increase is 27.01%. The results illustrate the feasibility and efficiency of the proposed synchronized loading and unloading containers method by comparing with the traditional operations method.
