An Exact Algorithm for the Pickup and Delivery Problem ...

    https://pubsonline.informs.org/doi/10.1287/trsc.2019.0905
    Research on exact methods to solve the pickup and delivery problem with time windows (PDPTW) and its variants has mainly focused on branch-and-price-and-cut algorithms. In this paper, we propose a novel exact approach based on fragments— a series of pickup and delivery requests starting and ending with an empty vehicle.Author: Ali Mehsin Alyasiry, Michael A.

    In the pickup and delivery problem with time windows (PDPTW), capacitated vehicles must be routed to satisfy a set of transportation requests between given origins and destinations. In addition to capacity and time window constraints, vehicle routes must also satisfy pairing and …Author: Stefan Ropke, Jean-François Cordeau, Gilbert Laporte

Exact algorithms for the multi-pickup and delivery problem ...

    https://www.sciencedirect.com/science/article/pii/S0377221720300771
    In the multi-pickup and delivery problem with time windows (MPDPTW) a set of vehicles must be routed to satisfy a set of client requests between given origins and destinations. A request is composed of several pickups of different items, followed by a single delivery at the client location.Author: Imadeddine Aziez, Jean-François Côté, Leandro C. Coelho

    The pickup and delivery problem with time windows (pdptw) is a generalization of the vrp which is concerned with the construction of optimal routes to satisfy transportation requests, each ...

The General Pickup and Delivery Problem Transportation ...

    https://pubsonline.informs.org/doi/abs/10.1287/trsc.29.1.17
    In pickup and delivery problems vehicles have to transport loads from origins to destinations without transshipment at intermediate locations. In this paper, we discuss several characteristics that distinguish them from standard vehicle routing problems and present a survey of the problem types and solution methods found in the literature.Author: Martin W. P. Savelsbergh, Marc Sol
