Abstract: The performance of the machine will be reduced after a long period of work, which will lead to longer processing time of the job. Hence, considering the deterioration effect caused by the machine, a non-permutation flow shop scheduling problem is studied. A mixed-integer linear programming model is firstly formulated to minimize maximum completion time and total energy consumption, and a two-stage whale optimization algorithm (TWOA) is proposed to solve this model. In the algorithm, the coding method based on the workpiece sequence is used and an initialization method based on the NEH heuristic is adopted to improve the quality of the population. The "better and nearest" individual is adopted and a two-stage global search is designed. At the same time, the tabu search mechanism is used to improve the local search ability. Finally, the simulation experiment is carried out to verify the effectiveness and superiority of proposed TWOA in solving the proposed problem.
