The increasing rate at which goods ranging from food products to electronic products are
consumed has led to rapidly increasing waste worldwide. This huge amount of waste poses …

In the past decades, there has been an increasing body of research in vehicle routing
problems involving cumulative costs. These problems consider cumulative objective …

We present a mathematical formulation and a heuristic solution approach for the optimal
planning of delivery routes in a multi-modal system combining truck and Unmanned Aerial …

In this paper, we conduct a comparative analysis of three synchronized truck-and-drone
delivery models for package delivery. In these models, drones are launched from the truck to …

The paper presents a Hybrid Tabu Search-Variable Neighborhood Descent (HTS-VND)
metaheuristic algorithm for the Cumulative Capacitated Vehicle Routing Problem with Time …

During natural disasters or accidents, an emergency logistics network aims to ensure the
