A dynamic model for disaster response considering prioritized demand points

•Dynamic model for distributing relief items.•Demand points with different dynamic priority values, budget constraints and isolated demand points.•Distribution plan thought to be applied during a planning horizon with several time periods.•Objective function that integrates demand urgency and unmet demand.•Priority of demands is defined based on discretized version of deprivation costs.

This paper addresses the problem of distributing relief supplies after the occurrence of a disaster. We develop a dynamic model to serve demand, while prioritizing the response, according to the level of urgency of demand points. Our model is thought to be applied during a planning horizon and it considers dynamic demand, capacity constraints and priorities. To evaluate the applicability of our model, we use a real case study of a flood occurred in Colombia. We also test the computational solvability of our model and we propose and test different solution methodologies for solving larger instances of our problem.
