Consider Environmental Costs And Inland Transportation Network Optimization For A Container Port

With the recovery of the world economy,the rapid development of the China economy and the increasing level of national living standards;China's port throughput also appeared with the obvious pick-up trend;meanwhile,in recent years,containerization,shipbuilding level is getting higher and higher,The container throughput of the port increased significantly;and at this stage of China's port collection and distribution system there are still many problems,which take the container to see the inland set of distribution has brought no small challenge.In addition,according to statistics in recent years,shipping and related industries carbon emissions cannot be ignored,more and more people began to pay attention to shipping and related industries,energy saving and emission reduction.Based on the above background,this paper takes A port as an example to carry out the optimization of the container inland set distribution system considering the environmental cost in order to achieve the win-win effect of reducing the carbon emissions and increasing the profits of the port enterprises.Firstly,this paper analyzes the status quo of research on the status quo of shipping carbon emission reduction and the research and development of container gatherings at home and abroad.It is found that there are few researches on energy saving and emission reduction in China,which are mostly limited to qualitative analysis and lack of quantitative research.The environmental cost is rarely taken into account in the optimization of the network.Next,this paper introduces the related theoretical basis of shipping carbon emission cost and container port inland set.Secondly,the relevant theoretical basis of combinatorial forecasting is introduced,and the container throughput of A port in the next five years is predicted by the combination forecasting model composed of exponential smoothing method,trend extrapolation method and gray forecasting method.The forecast results show that the container throughput of port A will increase significantly over the next five years.Based on the analysis of the container collection and distribution system at the current stage,it is found that the throughput and delivery system will not be able to meet the increase in throughput in the next five years.Then,K-means clustering analysis was used to classify the 15 hinterland cities in Hong Kong to find the alternative cities of container inland transit stations.The number of transit stations and the specific construction sites were determined by the minimum cost model.On the basis of the above,the optimization model of the inland set distribution network of Port A container considering the environmental cost is established and solved.Finally,the paper analyzes the optimization results of the container inland set distribution and the three kinds of carbon tax rates with different standards,and draws the following conclusions:At this stage,the railway transportation in the A harbor collection and distribution system is seriously inadequate;Higher carbon tax rate,will make more container freight to rail transport transfer.
