The Optimal Research On The Multi-modal Transportation Routing Of Dalian International Shipping Center Of Northeast Asia

In recent years,with the development of e-commerce and international trade,the development of modern logistics industry in China has been developing rapidly.The development trend of specialization is obvious,and the scale and service capability of the industry have greatly improved,which has become a real pillar industry of national economic development.Logistics industry has been rapid development,increased competition,the urgent need to find low-cost,high-service mode of transport,multimodal transport is one of the solutions.But the path selection,optimization method has not yet so mature.In this paper,Dalian City,Northeast Asia International Shipping Center as the main research object,from the relevant literature research and examples of information to start,build multimodal transport model and transport network,pay attention to the model of practicality and operability,Dalian-centric transport Route to study,and the use of examples of the form of simulation,make it closer to the actual situation.With a view to the Dalian City,Northeast Asia International Shipping Center of the path planning to make practical recommendations.Considering the characteristics of land transportation and maritime transport,we construct the land transport model and maritime transport model based on the minimum time and cost,and make the transport node as part of the objective function.Under the multimodal transport time-cost model.The fast and non-dominated sorting genetic algorithm is used to design the multidimensional time-cost model.According to the results can be obtained in the form of public transport in the form of maritime transport in the selection of the advantages of line transport.
