A predictive production planning with condition-based maintenance in a deteriorating production system

摘要

In this study, a capacitated lot sizing problem (CLSP) which suffers uncertainty by the equipment degradation is investigated. Condition-based maintenance (CBM) is considered with aperiodic inspection at the beginning of every batch. And a prognosis threshold is taken to decide the maintenance action. A predictive planning model is proposed to make the production and maintenance plan considering the uncertain degradation of the equipment. The objective is to minimize the expected total cost during a finite planning horizon, including production, maintenance and depreciation costs. A two-stage relaxation heuristic algorithm is designed and the results show that the method has a good quality.
