The Research On Transportation Network Model Considering The Cap And Trade Policy

In recent years,the deterioration of the ecological environment and greenhouse gases,especially carbon dioxide emissions lead to worsening the global environment.Governments around the world have come to realize that the era of economic growth in exchange for economic growth has gone and introduced relevant policies to guide enterprises to develop low-carbon economy.China,as the world's main emitter of greenhouse gases,has put energy-saving and emission-reduction,the development of low-carbon transport into long term goals on economic and social development.With the gradual opening of the carbon trading market,enterprises have gradually realized that only by reducing carbon emissions in production and transportation,constructing low-carbon transportation system can they keep with the pace of the development trend of the age and achieve a win-win situation both for our economy and ecological system.This paper combines the theory of carbon footprint and basic transport model,add the carbon cap and trade mechanism into the basic transportation model.And makes a comprehensive analysis of the impact of carbon cap and trade mechanism on operational costs and network flow.Firstly,this paper gives a brief introduction of carbon cap and trade mechanism and the calculation method of carbon footprint,analyzes the impact of operational cost under the influence of related factors.Based upon basic transportation model,and taking into consideration of carbon cap and trade mechanism,we construct an optimized transportation network model applying 0-1 mixed integer programming method.Through the numerical simulation analysis of the model,we consider the influence on the enterprise's operational cost and strategy under the cap and trade policy from three aspects,such as consumers,suppliers,manufactures.the industry can use the model to develop a reasonable transportation route to reduce carbon emissions and operational costs.Above all,based on the traditional transportation model,the paper takes the carbon cap and trade mechanism and carbon emission cost into account,which help the enterprises achieve the optimal equilibrium between traffic and cost.
