Research On Multi-period Supply Chain Network Equilibrium Considering Asymmetry Of Inventory Information And Fairness Concern

The survival and development of enterprises are inseparable from the cooperation and communication with other enterprises.Enterprises are closely related to each other.They collaborate and influence each other.Through long-term development,fairness concern behaviors will arise among enterprises,not only for the same type of enterprises,but also for upstream and downstream enterprises.The 21 st century is the era of information,information exchange between enterprises is essential.The behavior of equity concern and the behavior of information asymmetry both have important influence on the equilibrium decision of multiperiod supply chain network.In this paper,a multi-period supply chain network model considering the asymmetric inventory information is firstly established,and a multi-period supply chain network model considering the retailer's fair concern behavior under the asymmetric inventory information is also established to further study the multi-period supply chain network.Finally,the influence of these two conditions on the equilibrium decision of multi-period supply chain network is analyzed by examples,and some reasonable suggestions are put forward.In this paper,the information asymmetry problem of multi-period supply chain network is considered when market demand is determined.Based on the variational inequality and dual theory,the equilibrium model of multi-period supply chain network is established.The effect of misstatement of inventory information on multi-period supply chain network equilibrium is analyzed qualitatively and quantitatively.The results show that when a manufacturer or retailer understates its inventory information,it will increase its profit,but it will damage the profit of the decision-maker who does not conceal the inventory information.High timings do the opposite,but increase the retailer's profits whether the manufacturer(retailer)reports low or high inventory information.Finally,the most favorable asymmetric inventory information mode and the appropriate parameters are given.It is of great guiding significance to the development of enterprises.In addition,this paper,on the basis of considering the asymmetry of inventory information,also considers the retailer's equity concern behavior,and establishes a multiperiod supply chain network equilibrium model that considers the retailer's equity concern under the asymmetry of inventory information.The influence of equity concern behavior on the utility of decision-makers and related variables in multi-period supply chain network under information asymmetry is considered by example analysis.
