Abstract: The present disclosure provides a computer-implemented method for constructing a hierarchical industrial knowledge ontology, comprising generating a multi-tier semantic graph model representing an industrial facility. The graph comprises an equipment components tier defining components that compose individual pieces of equipment, an equipment tier defining physical asset instances, an equipment-to-equipment connectivity tier defining physical connectivity relationships among the equipment, a flow tier defining directional transfer relationships for process or utility media, an equipment-to-function tier defining functional characteristics at the equipment or component level, a functional group tier defining nested functional subgraphs composed of multiple equipment and flow relationships, and an operating group tier defining outcome-driven subgraphs associated with specific operational objectives or modes.

Abstract: A method may include obtaining a graph including components of a facility and connections among the components, receiving a query corresponding to a subset of the components, and generating, based on the graph and according to the query, a visual representation comprising the subset of the components and connections among the subset of the components.
