Transort Mode Selection To Meet Compamy's Emission Target Under Low Carbon Environment

With the successful sign of the Paris agreement,people are paying more attention to greenhouse gases.It also drives enterprise to make efforts to reduce emission.In fact,some consumers,when they are making choices of buying products,are more sensitive to product's price,which makes them more willing to choose low-priced products.For those consumers,enterprises tend to choose one transport mode with lower carbon emissions.As for those who are more sensitive to time,they tend to choose a shorter transit time of products.In this regard,enterprises will choose more efficient means of transportation at the cost of high emissions.Therefore,enterprises,when facing different needs of consumers,are choosing the transportation modes not only depending;on.the transportation cost,delivery.time but also on.the carbon emissions.The previous scholars are considering more of products' transportation cost or transportation time.In this paper,we bring a third decisive factor,namely the cost of carbon emissions cost.Firstly,enterprise makes the transportation mode selection decisions under different emission mechanism.It is well known that there are three kinds of carbon emission mechanisms,namely the carbon limitation system,the carbon tax system and the carbon trading system.Facing with different customers,the choices of the mode selection are different.So,how to determine the corresponding mode of transport to maximize the profit of enterprises is the first problem to be considered in this paper.Secondly,customers with different demands are giving the price differently due to different distances.That's why we also need to determine the price of products.Finally,the author analyzes how the carbon emissions affect the profit or the optimal prices of products under three carbon emission mechanisms.The author not only put these questions in a two-stage supply chain,but also considers it in a three-stage supply chain network to determine the best transport mode selecting decision.Through comprehensive model solving process,we give the final results under different mechanisms.
