Abstract:A study has been carried out on the coordination mechanisms governing the closed-loop supply chain, with one supplier and two competitive retailers subjects under investigation, and a bidirectional risk aversion involved in the process taken into account. A coordination model of revenue sharing contract has been established on the basis of the analysis of characteristics of decentralized decision-making model and centralized decision-making model. Thus, the feasibility and rationality of the model have been verified by analyzing with numerical simulations the inter-relationship between the wholesale price, sales price, recycling price and the coefficient of risk aversion.
