Research On Network Equilibrium And Coordination Mechanism Of Aviation Logistics Service Supply Chain

At present,China's aviation logistics market is in a stage of rapid development,but the inconsistency between the sudden increase in capacity in the market and the gradual increase in customer demand has become increasingly prominent.Specifically,the lack of demand under the existing capacity has led to space utilization The low price,or the bursting phenomenon when the demand grows but the capacity is insufficient,all show a certain degree of imbalance between the market space supply and demand.With the opening of national policies to control freight rates in the domestic aerospace logistics market,how airlines coordinate market demand based on the two perspectives of capacity input and freight rate formulation has become the key to their foothold in the market.At the same time,considering that the aviation logistics service supply chain network also involves other business entities besides airlines,how to coordinate the transaction tariff and cabin volume of each link in the network is of great significance to the healthy development of the aviation logistics market.Taking the general equilibrium theory in economics as the cornerstone,and maximizing the profits of the nodes at all levels of the network as the optimization goal,by matching market supply and demand to maximize the benefits of each level of the main body,that is,the management of the aviation logistics service supply chain network reaches a balanced state.First,by constructing the profit maximization model of each layer of enterprises,using the variational inequality tool to merge the target models of each layer of enterprises,and establishing an overall balanced model of the aviation logistics service supply chain network,in order to obtain the optimal decision of each layer of node enterprises On this basis,the impact of the characteristics of each enterprise in different scenarios on the equilibrium state of the network is measured and analyzed.Secondly,due to the widespread competition in the aviation logistics network and the individual economic characteristics of the enterprises in the network,the service chain network cannot reach equilibrium under normal operation.Therefore,a profit sharing contract is introduced to coordinate the relationship between enterprises and seek a way to achieve equilibrium.Finally,the representative flight segment is selected for analysis in the empirical part,and the transaction rates and cabin conditions of each branch in the service chain network in its equilibrium state are sought.The established air logistics service supply chain network equilibrium model can effectively improve the market supply and demand structure,optimize the operating status of enterprises in the market,and improve the level of enterprise decision-making.
