Abstract: A method for generating respective self-description data modules with respect to at least one functionality and/or at least one component, device, or system, wherein a data collection is provided comprising engineering elements from at least one of the three data sources, where relationship information is ascertained in which each piece of relationship information is assigned to engineering elements of the data collection, a multigraph comprising nodes and connections between nodes is generated, a clustering method is applied to the multigraph to ascertain at least one sub-graph within the multigraph, a sub-graph is selected from the ascertained at least one sub-graph, and a self-description data module relating to a component and/or a functionality of the device or system is generated.

Abstract: A method for generating a digital twin of a system or device includes identifying component data clusters within the first data source, where the component data clusters are assigned or assignable component types or component ID information relating to the system or device, allocating a respective component type designation or a respective component ID information designation to at least one of the identified component data clusters, and generating and storing the digital twin of the system or device.
