Abstract
For the international exchange of goods, an exact estimated time of arrival (ETA), especially in case of delays, is of great importance. Using global data of the automatic identification system (AIS) a grid node is generated. The sum of such nodes and their connections form a routing graph. As an example, with one node of in total more than 100,000 nodes it is described how this point gets the maximum vessel length and draft assigned.
Highlights
Most of the goods are transported across the world’s oceans
Operational disruptions or weather-related delays may cause deviations from the actual timetable. It is of considerable importance for stakeholders in a logistics chain to be informed about punctuality or deviations from the timetable [Mestl, 2016]
In [Loh, 2015, p. 331] the Cost Consequences of a Port-Related Supply Chain Disruption, the advantages of a more precise Estimated Time of Arrival (ETA) are shown for Chinese ports
Summary
Most of the goods are transported across the world’s oceans. Since there are no fixed waterways by sea, with a few exceptions, every ship can freely choose its trajectory. Operational disruptions or weather-related delays may cause deviations from the actual timetable. It is of considerable importance for stakeholders in a logistics chain to be informed about punctuality or deviations from the timetable [Mestl, 2016]. A continuously updated Estimated Time of Arrival (ETA) is important. To determine this ETA, a routing graph that is as accurate as possible is a very important requirement [Toth, 2014]. 331] the Cost Consequences of a Port-Related Supply Chain Disruption, the advantages of a more precise ETA are shown for Chinese ports. Both papers clearly identify the ETA as one of the most important factors to reduce costs
