With the continuous growth of online commerce, managing last-mile deliveries has become increasingly complex, leading to higher costs and longer delivery times. New technologies have made it possible to use autonomous wheeled robots to support trucks, allowing for multiple deliveries to be carried out simultaneously. This thesis presents and analyzes an innovative strategy that combines trucks and robots to make the delivery process more efficient. Unlike other approaches, no depots are used for renting robots; instead, it is assumed that the robots are owned by the delivery companies, making the system less dependent on external factors and therefore easier to implement.
