Abstract: In view of the uncertainties in the remanufacturing process,a dynamic facility layout method for remanufacturing shop was presented.The uncertainties inherent in the remanufacturing process were described,based on which the stochastic logistics elements were analyzed for the facility layout problem.An optimization model for the dynamic layout problem in remanufacturing was formulated with the objective of minimizing logistic cost and relocation cost.A simulated annealing-based optimization algorithm was introduced to obtain the optimal facility layout scheme.The proposed method was demonstrated through a facility layout design for a machine tools remanufacturing floor.The optimal layout scheme and the performance of the proposed algorithm were analyzed through Matlab programming,and the effectiveness of proposed method was proved.

Key words: remanufacturing, uncertainties, facility layout, simulated annealing
