IFAC MIM 2019 Mission was to connect Control, Industrial Engineering, OR and Computer Science for better management decision-support systems in digital, resilient and sustainable manufacturing and supply chains in the era of Industry 4.0. The central theme of the 9th IFAC/IFIP/IFORS/IISE/INFORMS Conference on Manufacturing Modelling, Management and Control MIM 2019 was Digital, Resilient and Sustainable Manufacturing 4.0. Digitalization, resilience, and sustainability shape current and future trends in manufacturing modelling, management, and control. The aim of MIM 2019 was to bring together researchers and practitioners in automatic control, optimization, computer science, industrial and manufacturing engineering and supply chain management, to present and discuss emerging topics in modern manufacturing modeling, management, and control. MIM 2019 followed a rich tradition of previous IFAC conferences and symposia in Manufacturing and Logistics held in Germany. MIM 2019 focused in particular on the most innovative methods proposed in the last few years in the context of digitalization, risk management, and resilience in production and logistics systems in the 21st century.
