Today’s manufacturing encounters more customization, higher standard and shorter response time from the market and customers. Automation and digitalization provide a big improvement of operations level, but also significantly increase the difficulties and challenges of the real-time decision of daily operations. As such, traditional optimization approaches based on limited data information and simplified models, are struggling in providing the efficient real-time decision support. This talk focuses on the production planning and scheduling problems in modern manufacturing operations. A learning-based optimization framework is proposed to enhance the real-time decision-making for daily operations by utilizing the digital twin production systems and industrial big data. In this framework, we develop a novel deep programming method, as a plug-in optimization solver, to automatically generating the efficient real-time optimization algorithms via an off-line learning manner. Convergence analysis and computational budget allocation issues are discussed. Numerical results show the superiority of the proposed framework and its potential to enable the intelligent decision-making technology for the modern manufacturing operations management.
