In the age of smart industry, the developments in manufacturing technologies and automation, combined with the advances in data and AI technologies, lead to a change in how production planning and control decisions are made. There is also an increasing trend in digitized after-sales services offered by the manufacturers of the equipment used in production and service. Combined with the ambition to be more sustainable, flexible, resilient and cost-effective, these trends create new challenges for decision makers. The students in the manufacturing and maintenance track are equipped with the necessary skills and knowledge to address these challenges. The main topics of OML within the manufacturing and maintenance track include data-driven production planning and control, AI-driven decision support, business process optimization, AI-driven process management, digital and sustainable factories, collaborative manufacturing, design and real-time control of material handling systems, predictive maintenance, service control towers, and human performance.
