Abstract: The reassembly strategy of used components is an important factor affecting the cost of remanufacturing of used mechanical equipment. The uncertainty of the reuse strategy and the complexity coupling relationship between used components, make the optimization of the reassembly strategy more complex, and affect the multi-life cycle cost of product. A research on the reassembly strategy of used mechanical equipment components based on non-cooperative game is proposed, the multi-objective optimization model of reassembly strategy with cost and balance of residual service life is transformed into a non-cooperative game (NCG) model and a mapping relationship is formed. The cost and balance of residual service life of different reassembly Strategies are taken as non-cooperative game parties, fuzzy cluster analysis is used to form the strategic attribution of two players in the game, and the utility matrix is formed by combining the utility function of the players. The optimal reassembly strategy is obtained through the Nash equilibrium analysis of the utility matrix, to improve the short comes of previous methods which depend on experience or linear weighted. A used lathe C6132 is taken as an example, to validate the feasibility and effectiveness of the proposed method.
