核心概念
Improving response times for naval accidents through strategic vessel allocation.
要約
The paper focuses on optimizing the allocation of rescue crafts in the North and Baltic Sea to reduce response times for maritime incidents. It introduces a mathematical model to allocate vessels to stations efficiently, considering factors like tides and incident-prone regions. The study shows that the problem is NP-hard and proposes an Integer Programming formulation to address it. Different simplifications are suggested to enhance computational efficiency, with a case study comparing their effectiveness based on real-world data.
