Abstract: Past and recent events have shown that transportation infrastructure systems are highly vulnerable to natural catastrophes, unintentional accidents and terrorist attacks. Protection investments are instrumental in reducing economic losses and preserving public safety. A systematic approach to plan security investments is paramount to guarantee that limited protection resources are utilized in the most efficient manner. In this talk, several optimization models are presented to identify the infrastructure assets which should be hardened or protected to minimize the impact of external disruptions. We optimize dynamic investments over a planning horizon and consider both man-made disasters and natural catastrophes. In the first case, problems are modelled as a game between an attacker and a defender. In the second case, we consider a scenario-based modelling approach. To demonstrate how these models can be used to support efficient protection investment decisions for real transport infrastructure, two case studies on a railway network and a road network will be presented.
