| In recent years,China's consumption of transportation has increased rapidly,and now it exceeds 383 million 176 thousand and 600 tons of standard coal,accounting for more than 8.91%of the total energy consumption of the whole society.Freight transport,as an important part of physical transportation,has significantly increased its energy consumption and proportion,and has become a key area of energy conservation and emission reduction.From the perspective of future development,a reasonable transportation structure can reduce the energy consumption of the freight transportation system to the maximum extent under the condition of meeting the social and economic development demand,and straighten out the transportation price system,and can effectively improve the transportation cost of the low energy transportation mode(railway transportation and waterway transportation)in the transportation cost.Competitiveness will guide the development of freight transport structure to a more energy efficient and reasonable direction,so as to reduce the energy consumption of cargo transportation.This paper analyzes the three influencing factors of freight transport energy consumption,namely,freight turnover,energy consumption intensity and transport structure from the macro level.The change trend of transportation turnover and energy consumption intensity is analyzed and predicted.The forecast value is used as the simulation environment parameter,and the optimization of transportation structure is an effective means to reduce the energy consumption of the freight transport system.It also reveals that transportation costs have important significance to study the energy consumption of cargo transportation.In addition,the calculation method of the generalized cost of freight transportation is introduced,and the elastic coefficients of four kinds of goods are calculated on the basis of the demand equilibrium model.The demand response model of freight owners based on price elasticity is constructed,which is the foundation for the realization of the interaction between the freight owners and the transport enterprises and the mathematical model of the construction of the simulation system.Based on the simulation theory of Multi-Agent system,the simulation model of transportation cost adjustment is set up in the transportation energy consumption system.The three main bodies of the system,the government Agent,the transport enterprise Agent and the owner Agent,are abstracted to determine the demand response criteria of the cargo owner Agent for transportation costs,and the overall goal of the system is to reduce the goods.Transportation of energy consumption.Netlogo simulation platform is used to simulate the interaction between the subject and the subject,the subject and the environment.The simulation scenario of four different transport modes of transportation cost adjustment was designed.The change of each body,the change of transport structure and the change of the total energy consumption were analyzed.According to the results of the simulation experiment,the policy evaluation and decision support were provided for the energy saving and emission reduction of cargo transportation.In this paper,Multi-Agent simulation technology is used to analyze the effect of freight transportation costs on energy consumption.The simulation results show that a reasonable transportation cost system is formulated,and the real price signal is used to guide the owner to choose the lower energy consumption of railway transportation and waterway transportation.It can promote the optimization of transport structure and further reduce the freight system.Source consumption has a significant positive effect.At the same time,it also creates an experimental platform for the study of the influence factors of the freight energy consumption system,Multi-Agent simulation technology,which has an incomparable advantage for the visual research of the characteristics of the various main bodies under the complex freight transport energy consumption system,to make up the lack of observation data and so on,and to fill the present study of the goods.The transport energy saving policy is blank in visualization,dynamic and visualization.Therefore,the use of Multi-Agent technology to study the factors affecting the energy consumption of freight transportation is of great significance for the realization of the goal of energy conservation and emission reduction and energy sustainable development of the cargo transportation system. |
