A
database (POH) provides semi-structured data about a first deployed
system and other deployed systems, wherein each deployed
system is an industrial
automation system at a different location, and wherein each deployed system consists of modules. A
data ingestion component (DIC) uses an ontology (ONT) to integrate the semi-structured data into a single
knowledge graph (KG), by representing a structural development of each deployed system over time, by creating an event node (EN) for each structure-changing event in the deployed system and attaching a subgraph to the event node representing a context of the structure-changing event. A generative deep-learning component (DL) has been trained with the
knowledge graph to perform
knowledge graph completion. It receives as input a new subgraph with a new event node and generates a recommended action for a structural change of one of the deployed systems, by completing the new subgraph with at least one action node (AN) identifying the recommended action and at least one module node (MN) identifying a first module that is added, replaced, or removed by the recommended action in the first deployed system. This modelling strategy for the knowledge-graph breaks down the
continuous flow of changes at a customer site into a
discrete set of subgraphs for which well-established similarity
metrics exist, allowing for an automated recommending of changes to the deployed system. This
automation of a previously time-consuming, costintensive, and largely manual process yields a number of benefits.
