| Abstract | For a carrier, provide a large fleet of owned containers could generate unnecessary costs for maintenance of their inventories; however, if the fleet of owned containers is small, it might result in a large number of short-term leased containers. Thus, it is developed a linear programming model capable to determine the optimal fleet size of owned and leased containers that involves the difficulty of decision-making in an extremely unbalanced trade. The literature survey presents few publications that deal with the considered subject. The work developed for Imai and Rivera (2001) is examined by being more similar to the subject considered in this project. For dealing with the container fleet sizing for two ports and not admitting stochastic travel times inland of containers other procedures are examined. To solve the problem of own container fleet sizing for the carriers two methods are analyzed: probabilistic simulation model and linear programming model. The simulation model is developed for a small problem. As the growing of this model and the increase of the number of variables, the simulation model becomes difficult to control, because the change of the values of these variables would become very hard. The linear programming model is developed on the basis of the characteristics and definitions adopted for the simulation model. This mathematical model incorporates the existing stochastic inland times, in accordance with the adopted hypotheses. This model allows to assist the planner to make strategical decisions, with regard to the size of the fleet of containers necessary to attempt the demand of transport throughout the planning horizon, and operational, for presenting the flow of empty cont ainers between ports, as well as the amount of leased containers, if necessary, to carry through the special operations associated the peaks of demand throughout the period of planning. To test the consistency of the model, hypothetical scenes had been generated. By the results gotten for these scenes, it is showed the relation of the cost of leases containers and the cost of the transport of empty owned containers above the owned container fleet size. |
