Abstract: For the dynamic processing environment, the existing research on dynamic disturbance events mainly focuses on new job arrival and machine random failure, and rarely considers the influence of dynamic changes in the total number of machines (such as increasing and decreasing the number of machines). In order to make up for this shortcoming, a multi-objective flexible job shop integrated scheduling problem including new machine insertion, old machine scrap, processing speed selection and predictive maintenance(PdM) is studied, which includes new machine insertion, old machine scrap, processing speed selection and predictive maintenance(PdM). The specific research contents include: ① a multi-phase-multi-threshold PdM policy with processing speed selection, variable PdM thresholds and sixteen discrete inspection policies is designed based on the accelerated degradation Gamma process; ② an adaptive rescheduling strategy(ARS) is constructed for new machine insertion, old machine scrap and the scale of production scheduling problem; and ③ an adaptive bi-population cooperative multi-objective evolutionary algorithm (ABCMOEA) is proposed to address the concerned problem. In the numerical simulation, the effect of parameter settings on ABCMOEA algorithm is firstly investigated. Secondly, the effectiveness of proposed cooperative initialization method and three local search mechanisms is demonstrated by literature comparisons. Thirdly, the superiority of proposed ABCMOEA algorithm, PdM policy and ARS strategy is separately verified by comparing with other intelligent algorithms, PdM policy and rescheduling strategies. Finally, through sensitivity analysis, it is found that the selectable range of processing speed and maintenance level has a significant impact on the research of integrated optimization, and the former has a greater impact.

Key words: flexible job-shop scheduling, new machine insertion, old machine scrap, processing speed selection, maintenance level selection, predictive maintenance, multi-objective evolutionary algorithm
