Research On Price Strategy And Coordination With Contracts Of Closed-loop Supply Chain

The problems of population, environment and resource have been three major problems of the human society being faced, and environmental and resource issues is particularly outstanding in our modern society, and thus the development cycle and low-carbon economy has become the core of modern economy. The recycling project is also become an important strategy for modern manufacturing enterprises operation. This behavior on the one hand recycling business force the government environmental protection laws and policies related to external pressure. On the other hand, much as the recovery and recycling enterprises can reduce their production costs, has won the reputation of environmental protection, increase profits and increase market competitiveness. Study on the pricing and coordination mechanism design of closed-loop supply chain system is extremely important theoretical and practical significance for the recovery mode choice and performance management of the closed-loop supply chain system, and the income distribution and improve overall operating efficiency of closed-loop supply chain system etc.Although the study about the closed-loop supply chain system modeling has made great progress, the emergence of a number of pricing and coordination model in the past few years, almost all of these models based on the remain in the market demand is determined, information symmetry, and recycling products and no difference in the case of new products research, and the existence of these models are themselves one way or another theory and method defects, and there is a big gap for t the operation of closed loop supply chain management practices. The paper take full account of more realistic various circumstances, such as asymmetric information, multi-retailer competition and new product and the price difference between recycled goods, etc. The paper constructs the corresponding model, and analyses the pricing decisions. And to further explore the complex case closed-loop supply chain coordination mechanisms designed to achieve closed-loop supply chain coordination and efficiency of optimization. Its main contents are as follows:Firstly, the coordination of the closed-loop supply chain and its theoretical base are studied in the paper. These include:closed-loop supply chain re-definition content, and analyses the characteristics and key processes of the closed-loop supply chain from at the point of the integration of the forward and reverse logistics; And then the paper analyses the three different recovery models and the main features, and use game theory to analyze the stackelberg problems in the closed-loop supply chain, and describes the system design and coordination mechanism in the display principle, the mechanism for the follow-up to find a theoretical basis for the design.Then, the pricing and contract coordination design issues of closed-loop supply chain system are studied in the paper. The pricing and contract coordination design issues are studied under asymmetric information by building models of different recycling closed-loop supply chain pricing model, and analyze the optimal pricing strategies of each member and profits, and comparative analysis between variety of models; The paper propose a coordination contract revenue sharing costs to achieve the closed-loop supply chain coordination and efficiency of optimization; The pricing and contract coordination model of the closed-loop supply chain was constructed based on the situation of asymmetric information of the retailers recovery costs; By use of the game theory and optimization theory solve the decision-making model, the study found that retailers is always false information on their recycling motivation operating costs. For the asymmetric information situation, proposes a coordination contract revenue sharing costs, effectively drawing up the recovery of operating costs retailers misrepresent their self-interest behavior. Further expansion of the retail competition of the closed-loop supply chain system, studies on the contract pricing and coordination mechanisms, and analyzes comparatively with the pricing model about a single retailer above. Finally, the numerical simulation is analyzed to validate the models various conclusions.The differential pricing model of closed-loop supply chain system is built under asymmetric information assumptions based on the differences between the recycled products and new products. The paper analyzes and solves these models by use of game theory and optimization theory, and obtains manufacturers and retailers the optimal pricing strategies and profits, and proposes a coordination contract revenue sharing to achieve cost efficiency and optimization of the system., and differential pricing and non-differential pricing strategies were compared. The paper studies the differential impact of a new product and the recycling coefficient of substitution, the retailer's operating costs to pricing strategies and profits of the system. The result found that new products and the degree of substitution between recycled products make for the system members profit and system profit and channel efficiency.Based on the above research, and further the differential pricing model is built under asymmetric information of the retail operating recovery cost in the closed-loop supply chain system. By use of game theory and optimization theory, this model is analyzed and solved. The paper proposes a revenue and expenses sharing coordination contract to effectively fiction retailer false information on their operating costs under asymmetric information and recovery of self-interest behavior, and achieve coordination and efficiency of optimization of the closed-loop supply chain system. Finally, the numerical simulation is analyzed to validate the models various conclusions, and the paper analyzes the sensitivity of the main parameters, and compares with the previous model under asymmetric information. These results can provide a useful theoretical basis for the decision-making practice of corporate in the closed-loop supply chain.
