The Study Of Closed-loop Supply Chain Profits Comparison And Coordination

With the rapid development of science,technology and social economy, the re-use of the product resources caused widespread concern. The closed-loop supply chain integrates forward supply chain and reverse supply chain.It realizes the sales of the entire life cycle of the product, recycling, re-use and re-sale process. Implementation of closed-loop supply chain management not only can reduce enterprises’cost and increase efficiency, but also can protect the environment and conserve resources. Therefore, on the basis of the domestic and foreign scholars research about closed-loop supply chain, the paper briefly introduces concept,development status and future research directions of closed-loop supply chain. Combined with the prevailing uncertainties in our life, the paper in-depth studies the profites comparison and contract coordination of closed-loop supply chain.The main work of this paper are as follows:Firstly,under the random market demand,the paper uses two different cooperative modes to study supply chain profit distribution.Using of game theoretical knowledge, this paper introduces a shared contract under a random market demand,The article establishes Stacklberg game of supply chain and ZhangBoLun profit distribution model.Especially under the unequal competitive position, ZhangBoLun cooperation mode is better.Secondly,the paper studies the contract design of closed-loop supply Chain under the condition based on third-party assorted-recyle.We collect the discard products which are classified into two kinds.Considering the randomness of the market demand and the government incentives to manufacturer,this paper sets up the centralization decision-making and decentralization decision-making models of the closed-loop supply chain which is composed of manufacturer,retailer and third-party logistics provider.Therefore,it puts forward a revenue-and-expense sharing contract to coordinate the closed-loop supply chain,which makes the profit of the decentralized closed-loop supply chain equal to the profit of centralized closed-loop supply chain Thirdly,The paper studies recovery strategies of the closed-loop supply chain under distributor risk aversion.Considering the random market demand and the risk aversion characteristics,we establish two recovery modes which are the manufacturer’s responsibility and distributor’s responsibility.Then we get equilibrium optimal solutions under different model parameters.The paper analyzes and compares the impact on both recovery modes under the distributor of risk aversion characteristics. By comparing the two recovery modes, the paper provide a theoretical basis for decision-makers,and help them to make rational decisions.
