Research On Multi-model Of Freight Transportation Choice Based On Behaviour Analysis And Double-layer Game Theory

The cargo transport system is complex and interacts with each other with a wide variety of cargo types,various combinations of modes of transport and various external environments.With the continuous changes of transport for numbers and quality requirements,a single mode of transport is difficult to complete the current large volume.The use of two or more modes of transport cooperation,in a certain technical support,can quick and easy to complete transport tasks.In this paper,through the analysis of the behavior mechanism of multi-modal transport,the shipper,carrier and transportation manager are the center,and the game model is established.The main conclusions are as follows:(1)Through the analysis of multi-modal transport demand analysis and technical economic characteristics,select the optimal combination weight variable fuzzy model to design the freight multi-modal mode,and the factors influencing various transportation modes are analyzed synthetically.(2)The analysis of the selection mechanism of the goods transport mode,based on behavior analysis the shippers,carriers and transportation managers are chosen as stakeholders,and their targets are analyzed respectively.This paper analyzes the decision-making psychology,decision-making mechanism and decision-making process of the stakeholders' choice of goods transportation mode,which lays a theoretical foundation for the analysis.(3)Constructs the game model of shipper and carrier freight mode selection,studies the choice game of freight shipper and carrier transportation mode,and puts forward the development of multi-modal freight development based on dynamic game process.Then the simulation case is used to solve the model.The feasibility of the model is verified by the genetic algorithm based on the optimal response dynamics.It is proved that the game theory is suitable for the analysis and research of the cargo transportation mode selection.(4)Based on the multi-agent transport model,the dynamic planning model of the multi-modal transport scheme based on multi-agent is proposed.The emphasis is on the design of an autonomous negotiation mechanism to discuss the relationship between the carrier and the transport manager.Secondly,considering the autonomy,an autonomous negotiation mechanism is designed.The Lagrangian relaxation algorithm is used to solve the shortest path problem under time constraints,and the problem of multi-modal transport path selection is solved.Finally,the feasibility of the model is verified by simulation experiments.(5)Considering the transport managers,shippers and carriers,the upper level game model between the transport manager and the carrier is established,and the lower game model between the shipper and the carrier is established with the aim of maximizing the social benefit.And then builds a two-layer game model based on transportation managers,shippers and carriers.Then,three-step method is used to solve the problem,and a feasible solution is given.
