3. The optimization of the port queuing system
There is often exist an imbalance in port handling activities, the imbalance is caused by many factors, such as the number of port handling equipments, the arrangement of operating workers, the scale of handling facilities. For example, if the number of logistics handling machinery is underestimated, it will result in the handling goods to be stranded, and affect its economic benefits. And if there are too many handling machinery, it will form the unnecessary waste of financial and material resources. If the arrangements for handling operating workers are unreasonable, it will result in uneven division of labor and human waste.
