Industrial internet-of-things asset management system

A method for ranking a plurality of assets associated with a plurality of spaces, the method comprising:

• generating, by processing circuitry, a knowledge graph comprising a plurality of nodes, each node of the plurality of nodes being associated with (i) a respective asset of the plurality of assets or (ii) a respective space of the plurality of spaces;
• determining, by the processing circuitry, a respective initial ranking value for each node of the plurality of nodes;
• determining, by the processing circuitry, a count of outgoing links for each node of the plurality of nodes;
• performing, by the processing circuitry, a node ranking based on the initial ranking values and based on the counts of outgoing links to determine a respective updated ranking value for each node of the plurality of nodes;
• determining, by the processing circuitry, a respective criticality measure for each node of the plurality of nodes based on the respective updated ranking value;
• comparing, by the processing circuitry, the respective criticality measure with a predetermined criticality threshold;
• and
• generating, by the processing circuitry and in response to determining that the respective criticality measure is greater than the predetermined criticality threshold, a signal indicative of the respective asset associated with the respective criticality measure.
