Abstract: In the reverse supply chain(RSC) composed of a manufacturer and a retailer,quality uncertainty for recycling products may result in uncertainty of the recycling price.For this reason,considering the recycling price as a triangular fuzzy number,the basic point for recycling price fluctuation is decided with fuzzy theory and game theory,and two non-cooperative game equilibriums(Stackelberg equilibrium and Nash equilibrium) and a cooperative game equilibrium(coordination in price decision) are obtained.Moreover,fluctuating scopes of recycling prices under each equilibrium circumstance for the manufacturer and the retailer are presented.
