In the following paper the effect of some critical parameters on the efficiency of a logistics & transportation system operating within the supply chain supporting the large scale retail sector is presented. In particular a three stages supply chain made up by 5 suppliers, 3 distribution centres and 120 stores, is considered. A Modelling & Simulation based approach is used for investigating the relationship between the mean service level provided to customers and the organization of the unloading and loading operations at the distribution centres. To this end two critical parameters (the trucks arrival time and the trucks waiting time at the distribution centres) are considered.
