Joint Energy, Maintenance, and Throughput Modeling for Sustainable Manufacturing Systems
With increasing concerns on climate change and energy shortage, manufacturing industries must adopt more sustainable production and facility control strategies. Such strategies require operational practices that emphasize sustainability by considering economic, energy, and environmental aspects simultaneously. In this paper, a new combined production scheduling model that jointly considers energy control and maintenance implementation to address the concerns of energy consumption, intelligent maintenance, and throughput improvement simultaneously is proposed. Multiple measures are combined and evaluated using a single objective, i.e., cost minimization. Particle swarm optimization, with a local optimal avoidable mechanism and a time varying inertial weight, is used to solve the cost minimization problem to find a near optimal solution of production and maintenance schedules. A numerical case study is implemented and the results show that the cost per unit production can be reduced up to 27% compared to the existing benchmark strategies. The implications to practitioners with respect to the tradeoff between cost and throughput/energy consumption, and the model applicability considering energy tariff structure, are also discussed to provide more insights for using the proposed joint model in the real world. The proposed model advances the state-of-the-art on maintenance and energy scheduling, which is typically performed exclusively. It is expected to guide operational activities on shop floors toward sustainability.
