The transportation problem with packing constraints
( Elsevier Ltd , 2023 , Article)We address a new variant of the transportation problem, where a set of different commodities, available at several supply nodes with different prices, are distributed to demand nodes using a set of heterogeneous vehicle ... -
A variable neighborhood search for parcel delivery by vehicle with drone cycles
( Elsevier Ltd , 2023 , Article)In spite of the growing literature on and relevance of vehicle-drone parcel delivery, the logistical impact of cyclic drone flights, in which a drone launches and lands at the same node (as opposed to distinct sites) while ... -
The cost of carrier consistency: Last-mile delivery by vehicle and drone for subscription-based orders
( Taylor and Francis Ltd. , 2024 , Article)We investigate a deterministic last-mile delivery problem in which a firm delivering scheduled orders determines a subset of customers to be prioritized for drone delivery, relegating the rest to vehicle delivery. The ... -
Lower and upper bounding procedures for the bin packing problem with concave loading cost
( Elsevier B.V. , 2024 , Article)We address the one-dimensional bin packing problem with concave loading cost (BPPC), which commonly arises in less-than-truckload shipping services. Our contribution is twofold. First, we propose three lower bounds for ... -
