On‐Time Meal Delivery Assisted by Drone Resupply
Naval Research Logistics (NRL), Volume 73, Issue 7, Page 1047-1066, October 2026.ABSTRACT Ensuring timely delivery is crucial with the increasing competition in online meal delivery services. This requires the industry to adopt new technologies and the corresponding operational models, including the use of drones. Concerning the desired features of meal delivery, such as safety and reliability, we propose an operational model that ...

A Branch‐and‐Price Algorithm for the Symmetric Electric Traveling Salesman Problem
Networks, Volume 88, Issue 3, Page 354-368, October 2026.ABSTRACT The Electric Traveling Salesman Problem (ETSP) is a variant of the well‐known TSP in which an electric vehicle must visit a set of customers minimizing the total cost of its route. The vehicle is assumed to be equipped with a battery of limited capacity that may need to be recharged along the route.

Driver‐Centric Vehicle Routing for Parcel Delivery
Journal of Business Logistics, Volume 47, Issue 4, October 2026.ABSTRACT One issue parcel delivery drivers are facing in their workplace is the limited access to restrooms. Because drivers are constantly pressured to meet the demanding performance standards called work quotas, they have little time to visit restrooms while working, often forcing them to urinate into bottles in the back of their trucks.

Networks, Volume 88, Issue 2, Page 192-210, September 2026.ABSTRACT In response to the increasing volume of parcels, last‐mile delivery innovations are exploring the integration of multiple delivery modes. The most prominent examples are delivery vans that, next to being the base for the delivery tasks of their human drivers, also function as mobile launching platforms for drones or autonomous delivery robots.
