Sustainable Production: Technical products are complex systems that affect the environment through the use of energy and raw materials as well as through the generation of emissions. Solutions towards achieving a sustainable development demand a life cycle-oriented approach. The aim is to minimise costs and optimise revenues as well as minimise risks and environmental impacts throughout the entire product life cycle. Digital twins - the connection of the physical world with digital models - establish a framework to evaluate both energy and material efficiency in a production process.
