【Abstract】 To improve the efficiency of multi-modal transportation and reduce carbon emissions,the paper systematically studies the comprehensive optimization model and method of the path and transportation mode of multiple transportation tasks consi-dering carbon emissions.Firstly,from the perspective of multi-modal transport operators,a multi-modal transportation path integrated optimization model is established,with multiple tasks,considering carbon emissions.Secondly,according to the features of the problem,considering the integration of paths and transportation modes among multiple tasks,the path integration strategy is proposed and the cultural genetic algorithm of variable length symbol coding mechanism is designed.Finally,designing the example and solving it,it is found that the total cost after path integration is reduced by 3.47%,which proves the validity of the model and algorithm.The study shows that by adjusting the carbon tax collection program,multi-operators can be guided to adjust transportation plans and reduce carbon dioxide emissions.更多还原
