Pickup and delivery problems with transfers
We consider the Pickup and Delivery Problem with Time Windows and Transfers (PDPTW-T). In this problem, a set of transportation requests needs to be satisfied by a vehicle fleet and each request is associated with an origin, destination and specific time windows for service. Transfer points are locations in the network where requests can be transferred between vehicles and temporarily stored. Those transfer opportunities might help to facilitate constructing and maintaining more cost-effective and robust transportation plans. In this preliminary work, we investigate static settings, i.e., all requests (location and time windows) are known before the optimization, and identify circumstances in which transferring requests lead to improvements as well as suitable solution methodologies to tackle the problem. Based on this results, our goal is to investigate how transfers could provide the means to leverage routing strategies under dynamic settings, in which the set of transportation requests arrive in real-time and the routing plan needs to be adjusted accordingly to the new information.
An brief introduction into the Vital Logistics programme will be made, specifically about effective and efficient multi-channel and multi-company collaborations. A brief explanation of auctions applied to logistics service providers will be given, and some extra results will be explained. Subsequently, a brief introduction into the planning of collaborative multi-channel networks will be given.
