Cyber-physical ecosystems are among the most promising solutions to adopt circular manufacturing (CM), extending product lifecycles with customer-centric approaches that optimize energy and materials use in interconnected organizations. However, information sharing increases significantly, putting standardization at the top of the industry priorities. This paper reviews interoperability standards for circular manufacturing and devises initial guidelines for its identification and management in cyber-physical ecosystems. The study was conducted within the framework of KYKLOS 4.0, one of the innovative Horizon 2020 projects advancing the field. The results include (1) an overview of interoperability standards in manufacturing and (2) the proposal of a standards list to support circular practices. Our findings are relevant for identifying circularity requirements in cyber-physical ecosystems and defining an interoperability baseline. As more standards appear in the market, continuous interoperability assessment and cyber-physical structures for multi-standard scenarios must enter the manufacturers’ agenda.

ISO 10303 STEP AP209 edition 2 ISO (1994), ISO (2014a)[1,2] is a data model standard intended for data exchange and storage of simulation information. The standard has a wide coverage of FEA (Finite Element Analysis) information, but is missing certain features such as nonlinear FEA. This paper gives an introduction to the STEP AP209 standard and presents projects in which AP209 has been implemented.The study then identifies requirements that should be supported by a standard FEA data model, but are not fully covered by AP209. Each requirements are discussed in the context of how they are supported by existing major solver applications. Without giving detailed solutions for how these should be implemented in AP209, starting points for further research is suggested.
