Format of the files
Each file consists of 100 vessels (or ships) described one per line. The data of a vessel is represented by five integers separated by semi-colons.
where:
- id: number of the vessel.
- l: length of the vessel.
- a: arrival time of the vessel.
- m: movements (or containers) to be unloaded/loaded.
- p: priority of the vessel (1 ≤ p ≤ 10 where 10 is the highest priority, and 1 is the lowest one).
Restrictions considered in our articles:
- Quay length: 700 meters
- There is a safe distance between two moored ships. We assume that each vessel has a 2.5% of this length at each side as a safe distance.
- ceil(2.5% of its length vessel)
- Available Quay Cranes: 7
- The maximum number of assigned QCs by a vessel depends on its length, since a safe distance is required be tween two contiguous QCs (35 meters), and the maximum
number of QCs that the container terminal allows per vessel (5 QC). Both parameters are given by the container terminal.
- min(5, floor(length/35) )
- Movements of the Quay Crane per time unit: 2.5 movs/t.u.
