Branch‐and‐Cut POPMUSIC for the Electric Vehicle Routing Problem With Time Windows

Networks, EarlyView.
ABSTRACT Advancements in computer hardware and commercial software have enabled the use of branch‐and‐cut (BC) methodologies to address medium‐scale vehicle routing problems (VRPs). Despite the introduction of efficient heuristics in the literature, tailoring these approaches to suit various VRP variants, such as the electric vehicle routing problem ...
