Abstract: Material convergence (MC) in humanitarian logistics refers to the movement of relief supplies from donor sites to distribution centers in disaster areas, from which the final deliveries are made to survivors (last-mile distribution). We investigate how the choice of MC strategy (approach) affects the effectiveness of last-mile distribution. Specifically, we investigate the relative performance of the two frequently used MC approaches in terms of their ability to facilitate (propel) effective last-mile distribution. These two approaches are: (1) p–method (in which the most-urgent material always flows into disaster areas first) and (2) m–method (in which every shipment bound to disaster areas is comprised of a mix of urgent and less-urgent materials). We first analyze advantages and disadvantages of each approach from the theory perspective, and then perform numerical experiments to examine the specific conditions under which each approach performs most, or least, effectively. Results indicate that, in 83.3% of cases, the m–method (less widely used approach in practice) works more effectively than the p–method (more widely used approach).
