Many researches have been conducted to perform safety measures on ports by creating simulating models toanticipate the current situation in order to prevent delays and reduce cost. Studies have been conducted in schedule loading operations in container terminals to integrate optimization algorithms and evaluate performance via functions in the simulation model. For example, in a research done in [4], the main events are: initializing container sequence according to some dispatching rule, then the sequence will be improved by a genetic algorithm, and the objective function of a given scheduling scheme will be evaluated using a simulation model. Another model is designed to foresee the objective function and to remove poor solutions in order to decrease the simulation mode running time. Many tests have shown that scheduling problem of container terminals can be solved by simulation optimization methods
