Research On Dynamic Supply And Demand Matching Of Port Coal Supply Chain Considering Carbon Emissions

Affected by the energy structure,China’s coal transportation pattern has the characteristics of “north coal transportation to south” and “western coal transportation to the east”,and coal is an important energy source to ensure the normal operation of our national economy.Therefore,it is very important to ensure the efficient and coordinated operation of China’s coal supply and demand.At the same time,in order to respond to the development of low carbon,it is particularly necessary to study the low carbon status of the coal supply chain,a high carbon emission network.Here,this paper uses ports as key nodes to study the process of coal supply and demand matching in the port coal supply chain and its decarbonization.The specific research content is as follows:First,sort out the current status of port coal supply and demand matching,and define the significance of studying this matching process and its low carbonization.Summarize the domestic and foreign research trends of port coal supply chain,bilateral matching,carbon emission measurement and multi-agent system,and sort out related concepts to clarify the purpose,significance and key issues of the research content of this paper.Secondly,determine the basis for matching the supply and demand of port coal supply chains.Clarify the goals of the supply and demand matching indicator system,determine the indicator system of port coal supply chain supply and demand matching,from the port perspective,based on the influencing factors of port coal supply and demand matching.Thirdly,the supply and demand matching of port coal supply chain considering the decarbonization of supply chain is analyzed dynamically.Describe the problem based on the idea of a multi-agent system,while considering the coal transaction price and preference order,adding considerations to the economic indicators of carbon emissions in the supply chain,a dynamic negotiation model meeting distributed constraints is established,and a multi-agent interaction method including asynchronous weakly coupled search is designed to solve the model.Finally,a numerical example is designed to verify the applicability of the model andalgorithm.This is of reference significance for optimizing the dynamic supply and demand matching process of the port coal supply chain while reducing the carbon emissions of the supply chain.
