Abstract

Most existing inverse scheduling studies adjust processing times or resource parameters. They pay little attention to equipment degradation and maintenance decisions. To address this gap, this paper proposed a joint inverse scheduling and maintenance optimization method for permutation flow shops with equipment degradation. First, it built a maintenance-driven multi-objective inverse scheduling model. The model took sequence deviation, comprehensive adjustment cost and high-service-age exposure as objectives. Limited adjustments of the job sequence and the processing times created feasible windows for opportunistic maintenance. Second, it designed an improved VNS-NSGAII algorithm. The algorithm introduced adaptive variable neighborhood search, an opportunistic-window-induced processing-time adjustment neighborhood and a perturbation retraction mechanism. Finally, comparative experiments against NSGA-II, SPEA2 and MOEA/D verified the effectiveness of the proposed algorithm. Experimental results show that the method reduces total high-service-age exposure from 213.50 to 60.57 and high-service-age points from 13 to 6, at acceptable sequence deviation and adjustment cost. The method therefore offers a new inverse scheduling route for coordinating scheduling and maintenance under equipment degradation.
