A synchronized two-echelon vehicle routing problem with two objectives in urban logistics

Beschreibung

Increasing urbanization combined with still high amounts of greenhouse gas emis-
sions currently constitute two major trends city logistics has to cope with. Both developments impose severe challenges to sustainable high-quality urban freight transport. The use of emission-free or at least low-emission vehicles is one strategy. Cargo bikes fit perfectly well in this profile of requirements, although two drawbacks of this mode of transport, i. e., limited capacity and restricted operational distance, have to be taken into account. A two-echelon routing scheme with synchronization of vans and cargo bikes for transshipment
purposes can tackle the above mentioned drawbacks of cargo bikes. In addition to the economic objective of the problem also external effects (emissions and disturbance) are considered in the respective optimization model: on the one hand to form a holistic approach and on the other hand to tackle objectives of companies as well as of citizens and municipal authorities. Therefore, we develop a bi-objective bi-modal solution procedure for a two-echelon vehicle routing problem with synchronization between echelons and customer deliveries on
both echelons. Pareto-optimal solutions are found by a metaheuristic epsilon-constraint method. Preliminary computational results illustrate the influence of external effects on the modal split and can give planners decision support in using a sustainable and sophisticated urban freight distribution scheme.
