Taking the logistic system of a bulk cement terminal in port area A as the research object，a logical model is established based on the discrete event dynamic system theory to realize the logistics function of the bulk cement terminal. The selection scheme of cement silos with different strategy combinations is given to solve the mismatch between the maximum loading capacity of the terminal and the horizontal transportation capacity through analyses of the number and capacity of terminal silos，vessel waiting time，berth utilization，terminal capacity and so forth. Meanwhile，this paper sorts out the relationship of each subsystem. It uses simulation technology to determine silo configurations to improve the shipping capacity of the cement terminal and the overall benefit of the cement plant. The research results can provide an important basis for optimizing terminal shipping capacity and a reference for selecting the number and capacity of silos in the loading and unloading system of such bulk cargo terminals.
