Starting from the existing literature in Service Network Design Problems with asset management, the goal of this work is to manage the usage of containers, both at a strategical level, that is initial acquisition and allocation, and at a tactical level, that is usage and re-allocation. The expected outcome of the model is, given a hub-and-spoke network of terminals and marshaling yards and a set of commodities to be delivered within specific time intervals, the optimal number of containers to purchase and where to initially allocate them. Moreover, the model considers the possibility to rent idle containers as storage space at terminals for a fixed periodic fee, that is taken into account when computing the objective function.
