Skipping the Storage Phase in Container Transshipment Operations

The paper deals with the problem of scheduling the loading/discharging operations of two simultaneously berthed vessels, assuming that some of the containers discharged from a vessel must be directly loaded on the other one. For these containers also the stowage position must be decided. The aim is to minimize the time needed to complete all the operations required by the involved vessels. For this problem we present a mathematical model, a heuristic algorithm and discuss the computational results on a set of randomly generated instances.
