Abstract:

For the traditional flexible job shop scheduling problem, a joint optimization of machine dynamic pre-maintenance and green scheduling is considered to establish an integrated optimization model with the optimization objectives of minimizing maximum completion time, total carbon emissions, and total cost. An improved NSGA-II algorithm is proposed to solve the model. A three-layer encoding method based on process, machine, and pre maintenance is adopted to design a one-step decoding scheme that considers process allocation, machine selection, and machine pre-maintenance strategies. The algorithm improves the elitist retention strategy, designs an adaptive crossover mutation function with algebraic changes, and a mutation operator based on neighborhood search. The experiment validates the effectiveness of the improved algorithm in solving scheduling problems of different scales, the proposed dynamic pre-maintenance strategy can more effectively solve the collaborative optimization problem of pre-maintenance and flexible job shop green scheduling compared to other maintenance strategies.
