Nowadays, the complexity of the global supply chain is increasing. Thus, the vehicle routing
problem (VRP) has become a very important problem because of its practicality in real-world …

This research proposes a mathematical model for the vehicle routing problem (VRP), which
involves pickup and delivery of cargos to different depots. Vehicle capacity and energy …

Today, goods transportation is considered to be one of the most important activities of
national economics. Logistics and supply chain play an important role in the industry and …

Unlike classic vehicle routing problems, real-time vehicle routing problems (RTVRPs) are
real-world dynamic vehicle routing problems (DVRPs) in which customer requests are …

Split delivery heterogeneous vehicle routing problem with three-dimensional loading (3L-
SDHVRP) is a critical issue in manufacturing logistics. Current mainstream research …

Vehicle routing problem with time windows (VRPTW), which is a typical NP-hard
combinatorial optimization problem, plays an important role in modern logistics and …

The increasing focus on environmental regulations and the economic advantages of
