Abstract: City Logistics has been introduced to study and understand the transport activities in urban areas. Optimisation of urban delivery planning needs to take into account the dynamics of the city in order to provide efficient services. In nowadays delivery systems it is common to forbid heavy trucks to enter city centers. Trucks are forced to unload at logistic platforms located in the outskirts of the city. Merchandise is then loaded into smaller (and possibly eco-friendly) vehicles in charge of final delivery to customers. First we present a survey of the movements of goods that occur in cities. This motivates the study we conducted and the development of optimisation tools for delivery activities in urban areas. Second, we introduce the Multi-Trip Vehicle Routing Problem with Time Windows and Release Dates. Routing problems that take into account time windows and multiple delivery trips are commonly studied by the scientific community, especially when applied to the urban context. On the other side, the study of routing problems that consider release dates on the products is not. Here the release date models the instant the merchandise is available at the logistic platform and ready for final dispatching. A genetic procedure is presented to tackle the problem.
