Vehicle routing

Definition

Vehicle routing is the process of determining the most efficient routes for a fleet of vehicles to deliver goods or services to various locations. This concept is crucial for optimizing logistics and supply chain operations, minimizing travel costs, and improving service quality. Effective vehicle routing involves considerations such as vehicle capacity, delivery time windows, and customer demand, which makes it an important area of study in operations research and optimization.
