Abstract:

In the container feeder liner operation, there are uncertainties in the freight demand, the container handling rate, the sailing time and the waiting berth time. In order to optimize the cargo rejection rate and ship capacity, the arrival on- time rate and committed arrival time of given route, all of the above distributions need to be nonlinearly superposed. As for this, the shipping voyage simulation which includes the speed adjustment for arrival on- time is introduced into our model and algorithm. In the numerical example, the shipping voyage simulation diagram of uncertain arrival time is showed. Meanwhile, the ship capacities, ship rents and cargo rejection compensations under different cargo rejection rate are calculated. Both of these help to verify the effectiveness of our model and algorithm. After observing the arrival time distributions with the speed adjustment or not, it can be found that adjusting speed contributes to arrive ontime.
