Determination of the Number of Yard Cranes in Container Terminal Charge/Discharge

As one of the most important equipments in container terminal charge/discharge,yard crane has much impact on the efficiency of the container terminal.In this paper,how to determine the number of yard cranes in container terminal charge/discharge is discussed,and the network flow model is presented.Then a minimum flow algorithm is suggested and proved reasonable and efficient. At last,a numerical example is given to validate the network flow model and the minimum flow algorithm.
