Integrated preventive maintenance and production scheduling optimization on uniform parallel machines with deterioration effect

Abstract

Integrated preventive maintenance (PM) and production scheduling problem has become one of research hotspots, but few research discusses the topic under uniform parallel machine system with deterioration effect. In this article, both characteristics of uniform parallel machines, deterioration effect of machine and job are considered, flexible PM strategy is adopted and integrated bi-objective optimization model is proposed. To verify this model, a numerical example with two machines and 40 jobs is provided, and by using NSGA-II algorithm, a set of Pareto optimal solutions is obtained.
