For dynamic scheduling of the machine breakdowns in the flexible job shop production environment, the multistage man-machine cooperated dynamic scheduling strategy is proposed to minimize the maximum completion time and the minimum deviation combining with the experience of the shop scheduling staff. The shop scheduling staff ccan participate the optimization process in the different stage to improve the feasibility and stability of the solution. An updating method is designed to update the optimal solution of the external elite library. Various schedules are saved with the same optimal fitness value according to the Hamming distance. The simulation results show that the proposed model and algorithm are effectiveness, feasibility and stability, so as to effectively guide the production practice.
