Research On Shipping Route Schedule Optimization For Container Liner Considering Carbon Emission Cost

Last decade, excessive emissions of greenhouse gases causing global warming growing, shipping emissions of greenhouse gases caused widespread concern and gradually become a new focus of international climate negotiations. World powers, led by the European Union introduced the monitoring, verification and reporting measures for the shipping industry in greenhouse gas emissions, the International Maritime Organization is working on the introduction of appropriate policies such as the imposition of a carbon tax and the implementation of maritime shipping carbon emissions trading mechanism to control shipping emissions. Therefore, how to take measures to deal with maritime shipping restrictions on carbon emissions has become an important issue they face in the management process. Discussion shipping industry accounts for the largest proportion of CO2 emissions from container ships carbon emissions, the introduction of low carbon concept container liner shipping arrangement optimization meaningful and forward-thinking.Chinese shipping companies can not be measured based on the carbon emissions of its own ships, carbon emission standards can not be defined exemptions and EUA, CER price estimation method yet, shipping companies using methods common carbon tax research. This article will be converted to carbon emissions carbon emissions environmental costs, the establishment of the company’s total profit maximization objective liner container shipping arrangement optimization model, and applied to a C liner company operated six liner routes and 15 ships container transport network consisting of the use of genetic algorithms to solve, namely the optimization of the cost of carbon emissions under the premise of considering the optimal speed of the ship and the shipping route peaks and troughs of each ship shipping boat with the results, and to explore the non-maritime carbon levy tax and levy low, shipping companies under the change in gross profit, high-grade carbon tax, the ship speed and shipping arrangement strategy.Solving the model show:When the container ship carbon tax, compared to the case without a carbon tax, a general decline in boat speed liner fleet, the company’s total profits fell liner; in the case of a carbon tax, the shipping market in the trough when when compared to the peak of the decrease greater boat speed, even when higher carbon tax, would be a serious phenomenon of idle ships, a serious decline in profits liner companies; shipping market conditions are the same, compared to low-grade carbon tax levy, in the case of high-grade carbon tax levy, the speed of the ship, although declining, reducing fuel costs and carbon emissions due to the high costs there may be a carbon tax and increase the company’s total profits lower liner; under the same market conditions, increasing the carbon tax ships idle increase, but are more reserved type boat to idle large ship, indicating increasing carbon emissions cost items reinforced liner fleet of economies of scale. The results show that the model established in this paper is reasonable and effective, can provide the basis for container shipping company in the case of a carbon tax to deal with maritime reasonable decision-making speed and route with the ship, and provide a theoretical basis for further study of the feasibility of a low-carbon shipping.
