Optimization of liner route allocation considering carbon emissions

Abstract

With the general awareness of energy and environmental issues in the whole society, the issue of greenhouse gas emission reduction has gradually become the focus of attention. Ocean transport undertakes more than 90% of the world's cargo transportation and also produces a large amount of carbon dioxide. In order to achieve carbon emission reduction in the shipping industry, in June 2012, the ECOFIN proposed to impose a Maritime Carbon Tax, which will increase the operating costs of shipping companies. In view of this, it is of great significance to consider carbon emission factors in the optimization of liner routes. This paper considers the carbon emissions of maritime transportation, establishes a mathematical model that minimizes operating costs such as maritime carbon tax, ship management fees, and fuel costs, verifies the effectiveness of the algorithm through calculation examples, and provides a plan for the carrier to make optimization decisions on liner route allocation.
