Study on the effect of carbon emission trading mechanism on logistics distribution routing decisions
To solve the logistics distribution routing problem under the carbon emission trading mechanism,we introduce a carbon emission calculation method considering the vehicle load and speed.Based on TSP model,a logistics distribution routing model under carbon emission trading mechanism is proposed.It is shown that the routing arrangement under carbon emission trading mechanism is better to reduce carbon emissions over the traditional routing arrangement only considering economic cost.We analytically and numerically examine the impacts of carbon trade,carbon price and carbon cap on routing decisions,carbon emissions,and total cost.We make some interesting observations for logistics companies about how to control cost and reduce carbon emissions from the numerical analytical results.
