Increased volatility continues to challenge the automotive manufacturer's production performance. More than a century after the start of mass production, changeable production systems that allow the flexibility for the economic mass production of customized products have arisen. Limitations on established production systems are driving the development of changeable production systems like the Fluid Manufacturing System (FLMS). In an FLMS, the individual production modules are mobile and consist of Cyber-Physical Systems (CPS) which can be combined ad-hoc to adapt to changing requirements. By connecting different CPS - e.g., Autonomous Mobile Robots (AMR) or smart load carriers - adaptable and flexible production will be achieved. This paper presents the first real-world initiation of an FLMS with the design and development of CPS and digital twins for production and logistics at the ARENA2036 research campus.
