Abstract: System and method enable development of an industrial metaverse used in engineering by computer aided design. A metaverse pipeline includes a plurality of metaverse entities including at least one design application and one simulation application configured to develop a virtual environment metaverse representation of an industrial facility. A metaverse knowledge graph describes semantics and relationships between the metaverse pipeline entities and is configured to exchange information across the software applications of the metaverse pipeline entities of various platforms while developing the virtual environment metaverse. The metaverse knowledge graph enables synchronization across metaverse development platforms, such that updates to one platform are transferrable, whereby the virtual entities and environment can be assimilated according to new edits.

Abstract: Device, Computing Platform and Method of Analyzing Log Files of an Industrial Plant are disclosed. The method including: determining at least one block in log entries of the log files, wherein the log entries includes one or more log messages and wherein the block represents co-occurring log messages; annotating the co-occurring log messages of the block using semantic metadata, wherein the semantic metadata defines one or more message types for the co-occurring log messages, wherein the semantic metadata is indicative of at least one of a start action, an end action, a source, an anomaly, a cause and an inspect action; generating a coherent representation for the block by representing the co-occurring log messages in a graph based on the semantic metadata; and enabling detection of at least one event in the block based on a comparison the coherent representation with template representations of predefined events associated with the industrial plant.

Abstract: To create or update a digital twin modeling a physical system, data from several conjoint data sources are repeatedly extracted and semantically annotated, wherein semantic annotations of data that have been extracted from a first conjoint data source are influenced by previously extracted and semantically annotated data from at least one other conjoint data source. The semantically annotated data are used to create or update the digital twin. This provides a modular and easily expandable solution for enriching a digital twin from a plurality of conjoint data sources with heterogenous data. Processing of different data sources does not happen isolated from one another while the system remains modularly expandable to new data sources. Compared to previous approaches, instead of creating yet another stand-alone digital representation of the physical system that is not compatible with already existing solutions, these solutions are augmented with a modular data management pipeline.

Abstract: A method for generating graph-structured representations of a brownfield system including collecting training data of training systems. Training data includes training pairs, with each training pair including training sensor observations and a training digital twin model. The method includes transforming the training digital twin models into training graph-structured representations. The training graph-structured representations include nodes and links. The nodes represent components of the training system and the links represent relations between the components of the training system. A graph generative model is trained to generate graph-structured representations of the brownfield system using the training sensor observations and the training graph-structured representations of the training digital twin models. Graph-structured representations of the brownfield system are generated using the trained graph generative model and sensor observations of the brownfield system.
