Research On The Optimization Of Container Multimodal Transportation Route And Transportation Mode

With the rapid development of the world economy and the rapid development of the globalization process,the trade between countries is getting closer and closer,so that the container transport business,which bears the role of trade bridges in various countries,is growing rapidly.The joint transport system,take port as the center,has become the most important mode in current international logistics transport.So,as a provider of transport services,the efficiency of transportation,improvement of efficiency and the enhancement of the level of service have become their urgent problems.And how to choose the proper way of transportation and the way to improve the efficiency and reduce the cost of transportation has become the focus of academic research.In this paper,through the analysis of the various factors in the container multimodal transport system,after systematic analysis on the process of container multimodal transport system and the transfer station,the network model of the city as a node and the transportation route as arc is established.On the basis of comparative analysis of various modes of transport,considering the cost of transportation,replacement and time penalty in the process of container intermodal transportation,then use the improved genetic algorithm to solve the model.Based on the standard genetic algorithm,the migration operator is added,ensure the diversity of population,avoiding get local optimal solution,enhance the ability of search algorithm.At last,the simulation experiment is carried out by using MATLAB,verify the rationality of the model and the feasibility of the improved algorithm.Final results show,the use of multimodal transport network operation model,at a certain extent optimized the transportation service chain,improved the efficiency of transport,saved the cost of transportation,thus improved the economic benefits of multimodal transport.
