Research On Decision Model Of Two Competitive Closed-loop Supply Chain Under Different Information Structure

With the development of social economy,science and technology,the disadvantages of traditional extensive development are becoming more and more obvious.Due to excessive exploitation,energy will eventually be exhausted,it will threaten the sustainable development of human society.So the countries around the world have introduced relevant laws and regulations to protect the deteriorating living environment.In the face of various restrictions and constraints,the traditional supply chain has been unable to meet the needs of social development.At this point the emergence of closed-loop supply chain to save resources and protect the environment opened up a new path.In addition,under the impetus of economic globalization and informatization,the connection between enterprises is becoming more and more closely,and the competition among individual enterprises has gradually changed into competition among supply chains.Combining these two trends with historical background,also,from the perspective of closed-loop supply chain competition,this paper use the theory of game theory,decision optimization theory and equilibrium analysis to study the decision model of two competitive closed-loop supply chains under information symmetry and the recovery channel selection under information asymmetry and information sharing.The main research contents are as follows:1.The selection of decision model under information symmetry when two competitive closed-loop supply chains are recovered by the retailer,the manufacturer and the third party is studied.Three kinds of competitive models of the centralized,decentralized and mixed decision-making are established under different reverse channel.By using the inverse induction method,the equilibrium revenues of the two supply chain are obtained.Then the impact of competitive intensity on the choice of decision-making mode,recycling subsidies and the profits of supply chain members are discussed.Also,the critical conditions of the optimal decision-making mode selection under three different recycling channels areobtained.Finally,numerical analysis are to verify relevant conclusion and theorem.2.The selection of reverse channel under asymmetric information and information sharing is studied.Three kinds of competitive models of retailer recycling,manufacturer and third party recycling are established.Using the backward induction method to obtain the equilibrium solution of the corresponding model.Then the impact of competitive intensity on the choice of recovery channel and recycling subsidies are discussed through numerical simulation analysis under asymmetric information.At the same time,the critical conditions of the choice of recovery channel and the corresponding equilibrium characteristics are obtained under information sharing.In addition,the sensitivity analysis of the relevant parameters is carried out to obtain their effects on the optimal solution and profit of closed-loop supply chain.
