Data flow: 
Timetable 
Checked: 
1. Origin 
• The origin of the timetable must be known. 
2. Validity 
3. Quality 
• The set parameters of the timetable must not contradict one another, eg set speeds and given 
arrival times. 
4. Harmonisation 
• Set parameters stipulated in the timetable must be observed under the boundary conditions ex 
pected. This comprises in particular the weather and sea conditions to be expected as well as 
the ship’s load state and stability behaviour. 
5. Criticality 
• Since the timetable forms the essential basis for voyage planning, any fundamental change in the 
timetable (modified passage and arrival times, change in the destination ports) will entail the inva 
lidity of the voyage plan, which means that in this case re-planning is necessary.
