Column generation for vehicle routing problems with multiple synchronization constraints.
European Journal of Operational Research(2019)
摘要
•Ground handling modelled as vehicle routing problem with multiple synchronization constraints.•Problem covers all five synchronization types, making it a vehicle routing problem with multiple synchronization constraints archetype.•Two flow formulations to efficiently model all synchronization constraints.•Branch-and-price heuristic with novel fixing technique finds near-optimal solutions.
