Liner ship speed optimization based on the influence of emission control area in waterway transport system

With the development of green transportation, many effective measures have been proposed in the waterway transport system. In order to save navigation costs and reduce carbon emissions under the emission control area (ECA) policy, this paper first establishes a mixed integer linear programming model to optimize the speed of the liner ship inside and outside the ECA; then a liner route is taken as an example to verify the model; finally, the speed optimization effect of the model under different fuel prices and carbon emission tax rates is analyzed through experiments. The results show that the proposed model can save voyage costs under the ECA policy and different carbon emission tax levels.
