Intermodal Logistics System Simulation Model and the Empty Container Flows

Abstract

"The average container is idle or undergoing empty repositioning for over 50 % of its life span..." (CRINKS Paul, 2000) High volume of empty container movements and low container productivity are the main problems of the container logistics. Like with all trucking companies, whether they will admit or not, we don't know where all our trailers are..." (Brown, Ike. Co-owner of National Freight Company). The high dynamism, complexity and myriad of delays render the logistics structure more difficult to manage and control. The alterations in the demand generate fluctuations in the behavior. On the other hand, the high dynamism and complexity make it difficult to envisage the whole mental picture of the logistics structure. A generic simulation model of an intermodal logistics system is created to draw this mental picture and System Dynamics aspect led us thorough this high dynamic and complex path. The main shortcomings of the structure are simulated, the causes of the shortcomings are analyzed in detail and possible policies are developed for the cure.
