Study on the mechanism of container port congestion under the epidemic

ABSTRACT

First, this paper analyzes the congestion of container ports at home and abroad under the current epidemic situation, then takes Yantian port of Shenzhen as the key research object to analyze the waiting time at anchorage and the stopping time at berth of the main container ports in China based on the data statistics. It studies the anchorage demand of ships with random and fluctuating arrival based on queuing theory. It gives the relationship between the stopping time of ship at berth and the maximum waiting time of the arriving ship, and reveals that the increase of ship stopping time and uneven arrival at the port are the main factors causing the current container port congestion, and puts forward some countermeasures to alleviate the port congestion. © 2022 SPIE
