Based on the analysis of the operation of container terminal,we put forward the idea on improving the operation efficiency by planning the block length reasonably.Moreover,we build the container terminal operation simulation model based on the computer simulation technology and research the effect of block length and equipment number on the operation efficiency of container terminal through simulation experiments.The results show that under different combinations of equipment number,the highest efficiency corresponding to the block length is different;by this model,we can analyze the effect quantitatively and provide an effective tool in port planning and operation.
