The Mixed Recycle Price Of Closed-loop Supply Chains Under The Condition Of Time Delays

Recently,the development of social economy has not only destroyed the environment,but also increased the contradictions between economy and resources.Thus,many researchers pay attention to the utilization of natural resources.The environmental,legislative and economic factors encourage people to consider Closed-Loop Supply Chains(CLSC).In order to reuse of resources,people makes the traditional supply chains turn to combination of the forward logistics and reverse logistics.The CLSC,which protect the ecological environment and are in line with the construction of a “resource-saving and environment-friendly” concept,have important social significance.On the one hand,in the CLSC,the participants in the decision-making process are often affected by the time lag of the transmission of information.They cannot be shared in time and cannot correctly judge the dynamics of the other participants in the moment.On the other hand,the participants lack of self-awareness and their own understanding of the existence of the lag will affect their decision-making.Therefore,studying the effect of time delay not only is consistent with the actual life,but also has important practical significance.Under the influence of time delay,three different recycling modes are analyzed,including the retailer and the manufacturer,the manufacturer and the third party,the mixture of the party,and the retailer and the third party in this thesis.In the absence of a leader,the participants of three different recycling modes of Nash equilibrium are investigated.Under the different recycling modes,the CLSC models are established.The price and profit of manufacturers,retailers and third party collection are studied.It shows that:(1)Under the three recovery of mixed modes,the time delay effects on the stability of equilibrium are analyzed in discrete time system.It's clearly that delay of information lag may affect the enterprise decision.But it will not affect the equilibrium point which means the sensitivity of the enterprise to the marginal profit of the current period will not affect the stability of the system.(2)In different mixed recycling modes,the price adjustment parameters will affect the degree of difficulty of the system into the stability,but will not affect the stability of the system.(3)In those three recovery modes,the delay parameters will affect the stable field of the system,but will not affect the stability of the system.
