Optimal Routing Algorithm Design And Simulation Of Container Sea Rail Transportation

The proportion of container sea-rail transport is generally increased year by year.Compared to China's,the proportion of transport is very low;In recent years,the international trade continued to decline,the shipping industry is faceing huge losses.At present the shipping industry competition situation is more severe,the container transport companies can not substantially increases the price of mileage to increase profits as before.Therefore,in order to ensure the safety of containerized cargo transport,how to link the various modes of transport,optimize the transport path,control their costs at a minimum is the focus of increased profits.In this paper,the research is mainly carried out from three aspects.First,in view of the high cost of container transportation and the slow development trend,the paper analyzes the present situation of the development of container sea-rail transport domestic and foreign,the optimal path algorithm,such as the classic Dijkstra,Floyd ant algorithms,and the development of the algorithm in the sea-rail transport;proposes the suggestion to increase the sea-rail transport mode of transport between the convergence and optimize the sea-railway transport routes;Second,analyzed the path coverage algorithm and rail transport path optimization algorithm,and proposed the improved the designed algorithm,and compared the traditional and designed algorithm search efficiency.Then establish the multiple constraints sea rail transport model and considering the time waiting for the train,cost factors such as path length,the improved ant colony algorithm is used to solve the optimal path problem under multiple constraints.Third,with the help of computer simulation technology to solve the problem.Using the GIS map of Anylogic simulation tools,the improved algorithm is applied to the rail transport optimization route choice and compared with different rail transport path time through the case analysis,provides decision-making basis for the container ports along the selected path planning.Through the simulation and solve the optimal selection problem in the sea and railway transport path,it will contribute to speeding up the rapid response capability of China's container sea rail transportation,saving operating costs and improving the competitiveness of container rail transport to increase the algorithm feasibility,economy,feasibility.
