First-mile logistics tackle the movement of products from retailers to a warehouse or distribution centre, and requires efficient methods different from those developed for last-mile delivery. Additionally, the pickup process is subject to different and impactful disruptions. We model the first-mile pickup problem as a vehicle routing problem for a heterogeneous fleet, with time windows andpacking constraints. Moreover, we propose an approach to tackle the problem on a dynamic setting, where the routes can be modified to accommodate disruptions that arrive progressively when the vehicles are already travelling. We propose a new algorithm for this problem to tackle these disruptions in a dynamic setting. The results allow quantifying the impact of disruptions in this context and demonstrate the value of efficient solution methods that are balanced, incorporate competitive packing algorithms and are tailored to tackle disruptions.
