The Ship Delay Recovery Problem with Variable Buffer Times



In liner shipping ships follow a fixed route within a fixed time schedule. Additional costs are incurred when ships are delayed. Delay can be handled in two different ways: prevention and recovery. To prevent ships to incur delay, buffer times can be added to the schedule. The buffer time will then be used to capture (a part of) the obtained delay. However, when a ship does not encounter delay during the trip, it has to wait before it is allowed to start with the new trip. The total amount of buffer time that can be allocated to a schedule is limited. On the other hand, ships can perform recovery actions to reduce the amount of delay. Examples of recovery actions are increasing the sailing or port handling capacity. In the ship delay recovery problem the objective is to determine a recovery policy that minimizes the costs associated to delays and recovery actions for a given liner shipping route with variable buffer times.
