Buyback Contract with Fuzzy Demand and Risk Preference in a Three Level Supply Chain
نویسنده
چکیده
F F Abstract—This paper analyzes the buyback contract of a supply chain including one retailer, one distributor and one supplier in a fuzzy decision making environment. The market demand is characterized as a fuzzy variable. To defuzzify the fuzzy number into a crisp one, the weighted possibilistic mean value method is applied, and the risk attitudes of the supply chain members are also considered. The centralized decision-making model and the buyback contract are proposed, and their optimal solutions are also derived. Finally, the impacts of the retail price, risk basic coefficient, and values of the contract parameters are analyzed for illustrating the results of the proposed fuzzy supply chain models with the help of numerical experiments.

Supply Chain Coordination Based on Buyback Contract under the Imperfect Product Quality and Fuzzy Demand Environments
The coordination of two-echelons supply chain by buyback contract under the imperfect product quality and fuzzy demand environment is investigated in this paper. The mathematical models are built based on credibility theory, and the optimal parameters of buyback contract are obtained. In addition, the influence of the imperfect product rate on the parameters of buyback contract is analyzed. Fin...

متن کاملChannel Coordination for a Supply Chain with a Risk-Neutral Manufacturer and a Loss-Averse Retailer
This article considers a decentralized supply chain in which a single manufacturer is selling a perishable product to a single retailer facing uncertain demand. It differs from traditional supply chain contract models in two ways. First, while traditional supply chain models are based on risk neutrality, this article takes the viewpoint of behavioral principal–agency theory and assumes the manu...
متن کاملAnalysis on the Stackelberg Game Model and Risk Sharing Based on Buyback Contract
This paper deals with the Stackelberg game model based on the buyback contract predominated by the supplier, and the equilibrium solutions to the model are available when wholesale price and maximum buyback rate are determined by the supplier and the order quantity is determined by the retailer with respect to the stochastic market demand. Coordination of different supply chains and risks share...
متن کاملCoordinating a decentralized supply chain with a stochastic demand using quantity flexibility contract: a game-theoretic approach
Supply chain includes two or more parties linked by flow of goods, information, and funds. In a decentralized system, supply chain members make decision regardless of their decision's effects on the performance of the other members and the entire supply chain. This is the key issue in supply chain management, that the mechanism should be developed in which different objectives should be align...
