Modelling for the optimal sizing of an automatic intermodal freight terminal

In this paper the problem of the strategic design of an automatic intermodal terminal is addressed. In particular, the considered terminal is supposed to be provided with an innovative transfer system (such as the Italian system Metrocargo) allowing to load/unload containers in a fast and horizontal way under the electric line. In this system, the main strategic decisions regard the number of shuttles, as well as the number of storage locations to be used in the terminal. At this purpose, an optimization problem is stated for determining the optimal resources in order to minimize the overall cost and taking into account some specific constraints. An algorithm is also defined for solving the proposed optimization problem.
