【 摘 要 】

This paper proposes a methodology toprioritize interventions in Peru's road network. Anetwork model is built, linking the country's economicand population centers through indicative corridors, whichare defined as the least-cost routes to connect origins todestinations. The network's critical links areidentified by systematically simulating disruptions andcalculating the costs associated with them. The network isthen overlaid with natural hazard layers. The average annuallosses associated with the hazard disruptions of thecritical links are calculated in many scenarios, includingclimate change uncertainty and different impacts andreconstruction times. A robust decision-making approach isthen used to select interventions that decrease hazarddisruption costs.
