In this webinar the partners of the FAIRWork project will provide an overview on the design thinking approach for creating user requirements. Afterwards, we explain the chosen overall methodology of creating complex decision-making. In this part we give an overview on relevant concepts for the research direction and implementation of such complex decision-making by using AI services. Technical concepts for a concrete implementation such as digital knowledge base, digital twin, and digital shadow will be discussed as well. Finally, an explanation of the orchestration of decision-making processes by using micro-services will be presented.
