During wildfires, community assets are at risk of being damaged or destroyed. Preventive actions can be carried out to protect these assets. The Asset Protection Problem (APP) aims at routing vehicles and teams in order to protect assets, under time windows and synchronization constraints. When a disruption occurs, vehicles need to be rerouted in order to take into account the consequences of the disruption. We studied the mathematical model used to represent the dynamic version of APP to deduce good valid inequalities based on the bi-objective and dynamic nature of our problem.
