Abstract: For the reversed supply chain system of dual channel recycling whereby the WEEE(waste electrical and electronic equipment) processor recycles itself and simultaneously commits its recycling partners to recycle， the recycling price is viewed as a triangular fuzzy number， and the fuzzy theory and game theory are applied to study the fuzzy recycling pricing of processing enterprises and recycling businesses under the decentralized strategy and centralized strategy. The floating reference point and the floating ranges of their respective recycling prices under the two mentioned cases are given， and the expected fuzzy profits are derived as well. It is shown that the centralized strategy can maximize the systematic profits by setting prices together， compared with the decentralized strategy under the dual channel recycling mode; thus， the centralized strategy tends to improve the systematic efficiency. Finally， an example is given to verify the conclusions.

Key words: EPR(extended producer responsibility), WEEE(waste electrical and electronic equipment), dual channel recycling, Stackelberg game, fuzzy pricing
