Research On Multimodal Transport Scheduling Based On Network Freight Platform

With the continuous development of China’s logistics industry,more and more emerging technologies have joined it,and the logistics industry has made great progress in the technical level.At present,the network freight operators have just entered the development period and are highly welcomed by the market.However,the network freight operators are also faced with the problems of single transportation mode and poor organization and coordination ability of actual carriers.They need to improve their coordination and scheduling ability of business on the basis of their own information resource advantages.The development of multimodal transport on network freight platform can effectively reduce the transportation cost.This paper studies the multimodal transportation scheduling problem based on the network freight platform with the technical support of the network freight platform:This paper summarizes the previous research on network freight and multimodal transport,and finds that the research on organization and scheduling under the network freight platform is insufficient in China.At the same time,it also studies and analyzes the algorithm of multimodal transport scheduling problem,and puts forward the algorithm suitable for multimodal transport and gives the basis.After analyzing the operation mode of network freight transportation,it is proposed that the multimodal transport mode of network freight operators can solve the problems brought about by single mode of transportation.In this paper,the mathematical model of the actual problem is modeled,the reasonable assumptions are given,and the variables are defined.Finally,a function model with the lowest total transportation cost is established,and the delivery time and receiving time in the transportation process are used to constrain the time.Firstly,a heuristic algorithm is designed to solve the initial solution,and then the simulated degradation algorithm is used to solve the optimal solution.After the multimodal transportation scheduling model and design algorithm based on network freight platform have been established,a case study is carried out for an actual network freight operator.By using the algorithm designed before,the multimodal transportation scheduling scheme is obtained.After obtaining the scheduling scheme,the results are analyzed,which provides a scientific basis for the network freight operator how to increase profits and reduce losses.By comparing with the traditional enterprise single transportation mode,the rationality and effectiveness of the multimodal transportation adjustment model and algorithm based on the network freight platform are verified.Finally,this paper studies the development of multimodal transportation scheduling transportation by means of data sharing mode,and puts forward the optimization strategy of multimodal transportation under the data sharing mode.
