About the Seminar
In this talk, we present an aggregate planning model for the deployment of a fleet of container ships to liner shipping services that are rotated around different regions of the world; It aims to maximize the total profit at strategic level, where cargo demands are aggregated by the regions of their origin and destination ports. The proposed model takes into account a joint optimization of decisions on the numbers and speeds of ships deployed for each service, together with the cargo flows. By separating the fuel cost of a ship into two terms, associated with the ship speed and load, respectively, we have obtained a mixed integer programming formulation of the model, so that it can be solved to optimal for up to give regions, which are commonly faced by practitioners in liner shipping. We have further conducted numerical experiments to demonstrate the accuracy of the formulation, the efficiency of the solution methods, and the performance of different deployment strategies.
