Research On Game Of Coal Supply Chain Information Sharing Based On Block Chain

Coal supply chain has the characteristics of large transportation volume,long transportation distance,including many nodes.For a long time,imbalance between supply and demand,waste of resources and low cohesion efficiency often occur in the operation of supply chain.The reason is the serious information asymmetry between nodes.The key to efficient operation of coal supply chain is to achieve the ideal state of collaborative decision and overall optimization through real-time information sharing.However,the traditional coal supply chain production information management system generally has the shortcomings of centralized management,difficult to ensure information security,low efficiency of information sharing.It is difficult to meet the demand of information coordinated development,which hinders the improvement of supply chain efficiency.This paper takes advantage of block chain’s decentralized,secure information transmission,non-tampering,traceability and other characteristics to propose that block chain technology brings a new mode of information sharing to coal supply chain.Using evolutionary game theory to further explore the decision-making rules of supply chain participating in node information sharing under block chain.So that the participating nodes are targeted to introduce block chain technology for information sharing.Realize the goal of supply chain coordinated development.This paper analyzes the main problems existing in the traditional coal supply chain information sharing,and expounds the applicability of block chain technology to solve the problem of supply chain information sharing.This paper puts forward the idea of using block chain to realize real-time information sharing,which brings a new model for information sharing of coal supply chain.The driving factors of information sharing in coal supply chain based on block chain are comprehensively considered from the three aspects of information subject,object and environment.Based on this,qualitative analysis of supply chain information sharing game.Using evolutionary game theory,this paper establishes the coal supply chain information sharing game model based on block chain,and analyzes the stability of the model.Explore the relationship between key influencing parameters and information sharing selection strategy of participating nodes.It demonstrates how to improve the enthusiasm of information sharing of multi-party nodes in the coal supply chain based on block chain.And based on the coal supply chain of TS port,this paper proposes the preliminary basis for introducing block chain technology into the coal supply chain of TS Port,and carries out the numerical simulation design of information sharing game based on block chain.Through the analysis of numerical simulation results,it puts forward relevant suggestions for the coal supply chain of TS Port to realize efficient information sharing by using block chain technology.
