Integrated Production and Maintenance Planning Considering Machine Degradation and Energy Consumption

Energy and environmental related performance of manufacturing systems has recently drawn great attention due to increasing concerns about climate change. Meanwhile, maintenance has also been traditionally considered a critical factor in improving equipment reliability and productivity in manufacturing systems. A great deal of research focusing on energy and maintenance issues in manufacturing has been implemented. However, most of the existing literature addresses the two issues separately and there lacks an integrated model that can direct manufacturing practitioners to make appropriate decisions considering equipment degradation, production throughput, and energy consumption jointly. In this paper, we propose a joint energy, maintenance, and throughput management model for sustainable manufacturing systems. It aims to identify an optimal production schedule that can minimize the total cost. A numerical case study is implemented to illustrate the effectiveness of the proposed method. Furthermore, a sensitivity analysis for the proposed model is conducted.
