Using sustainable delivery modes in a two-echelon last-mile delivery setting

Résumé

Last-mile delivery costs account for 50% of the total supply chain costs. Furthermore, last-mile delivery causes noise, pollution, emissions and the congestion of traffic in urban areas. Planners need to create a comprehensive delivery strategy to minimize costs and achieve sustainability goals. Therefore, interest in solutions using sustainable modes of transport for delivery in urban areas is growing. Since the sustainable modes of transport have a lower capacity and range, they are best employed in a multi-echelon setting. We consider a two-echelon multimodal vehicle routing problem for urban delivery, using porters and cargo bikes as sustainable vehicles in inner city areas while vans are employed in the outskirts. An intermediate zone where all kinds of vehicle are usable is considered. The vans start from a central depot while transshipment to porters and cargo bikes is done in mobile satellites. We propose a mathematical formulation that can solve small instances to optimality by a commercial solver. We also propose a large neighbourhood search to tackle larger instances. We consider different sets of instances from the literature and propose a new set of realistic instances that represent different city characteristics. In the computational study we analyse the impact of choosing different customer zones and multiple types of vehicles for the delivery. The computational results show the validation of the mathematical model and the heuristic on a set of small instances. Meanwhile, with the large data sets, the heuristic methods provide solutions that reach the expectations of reducing costs of delivering and obtaining sustainable targets. The study not only helps to plan the routes of deliveries in cities, but also supports policymaking.
