Dynamic Rescheduling for Optimal Transportation Incident Management in Inland Waterways

This paper proposes a novel two-layer monitoring and rescheduling approach designed for vessels navigating natural inland waterways, addressing diverse scenarios such as arrival delays, speed reductions, and machinery failures. Firstly, a methodology for incident detection and classification is proposed, which compares the planned trajectory of the vessels with their actual position provided by an automatic identification system. Secondly, in case an incident is detected, the plan for each vessel is rescheduled. To achieve this, various rescheduling strategies are proposed, taking into account the particularities of each incident. The aim is not only to ensure the safety and efficiency of the operation but also to minimize the impact of rescheduling on the original plan, thus averting any negative repercussions on the port's reputation. Different simulations have been carried out taking the Guadalquivir River as an example, demonstrating the efficiency of the proposed methodology in preventing incidents and ensuring optimality.
