Study On The Model Of Vehicles Assigned Under The Cap And Trade Mechanism

With the development of global economics, more freight transportation is needed by the company. At the same time, the greenhouse gas emissions coming from vehicles are more and more, so, it is a very important problem for us that how to reduce the carbon emissions coming from freight transportation. In order to deal with the over carbon emissions and also help the enterprises to reduce the carbon emissions, the United Nations have proposed three feasible carbon reduction mechanisms, one of them is called Cap and Trade. While, this article will research the problem like that:how the company to balance the relationship between the total costs and carbon emissions, by making the vehicles-purchasing decision and the vehicles-assignment decision under the mechanism of Cap and Trade.First, the thesis builds up a model of vehicles assignment with capital budget. It analyzes what would happen on the company’s total costs and carbon emissions while the company using the capital budget to purchasing the new energy vehicles. Under the Cap and Trade mechanism, the company might face different carbon prices, so, this paper will discuss how the total costs and carbon emissions would reflect when the price of carbon emissions is changing. After that, we will consider about the change of vehicles assignment under different carbon prices. For the company which has the budget for purchasing new energy vehicles, we analyze how the two factors which are carbon quota given by government and carbon price decided by carbon trade market affect the company’s vehicles purchasing decision. At last, we discuss the situation of company’s carbon emissions under different capital budgets.The government’s macro control is one of most important method for cutting down the company’s carbon emissions, so, our work proposes the factor of Over Emission Intensity (OEI). We discuss the effect of OEI on company’s total costs, carbon emissions and vehicles assignment decision. Then, the paper compares the method of macro control to the method of market control, and also discusses the effect of two methods on company’s total costs. According to analyzing the costs, we find out how the company controlling its total costs and carbon emissions through adjusting the vehicles assignment. Lastly, the article analyzes the effect of OEI on company’s vehicles purchasing decision and vehicles assignment decision.At the end of this paper, this article researches the effect of time window on company’s total costs and vehicles assignment decision. The time window represents the requirements of customers on service time. Different time windows require the company using different vehicles assignment schemes, so, it can also cause the changes of total costs and total carbon emissions. At first, according to adjusting the extent of customer’s time windows, we discuss the effect of time windows’extent on company’s total costs and carbon emissions. Then, the paper analyzes the change of company’s vehicles assignment decision and carbon emissions while the departure time of new energy vehicles is changing, at the same time, the company’s vehicles purchasing decision is also been considered. At the end, we find out the relationship between the departure time of traditional vehicles and company’s operation.
