点击翻译按钮获取中文摘要

We constructed a digital shipping route network of ships based on a shipping route chart, and we developed an simulator to do spatial-temporal analysis of international and domestic logistics using the vessel movements database. Then, we found the ports of call pattern of each vessel and considered the travelling salesman problem for ports of call. Moreover, we analyzed to influence that the change in the transportation network, for example, the detour for the pirate evasion and the use of the Arctic Ocean sea route, gave to the ports of call pattern.
