AI extensions and intelligent model validation for an industrial digital twin
Industrial smart data tags conforming to structured data types serve as the basis for creating a digital twin of an industrial asset. The digital twin can comprise an automation model and a mechanical model or other type of non-automation model, both of which reference the smart tags in connection with digitally modeling the industrial asset. The structured data topology offered by the smart tags allows the digital twin to be readily interfaced with artificial intelligence (AI) systems. AI analysis can leverage the smart tags to discover new relationships between key performance indicators and other variables of the asset and encode these relationships in the smart tags themselves. These enhanced smart tags can also be leveraged to perform AI-based validation the digital twin. Additional contextualization provided by the enhanced smart tags can simplify AI analysis and assist in quickly converging on desired analytic results.
AUTOMATED INSPECTION-PLAN BASED DETECTION
An inspection-plan based inspection method includes receiving data characterizing an inspection plan associated with inspection of one or more nodes in an inspection site by an inspection device.

Providing real-time feedback to a user from states of a model physical system via a surrogate function
The present invention is notably directed to a computerized method for providing real-time feedback to a user from states of a model physical system, or MPS, via a computerized system comprising one or more processors and a user interface system, or UIS. The method comprises the following steps, each performed via the one or more processors. Configuration inputs are repeatedly received, to modify a configuration of the MPS, said inputs including user inputs received via said UIS. While receiving said configuration inputs: configurations of the MPS are updated based on the configuration inputs received; and a state of the MPS is repeatedly computed, whereby each computed state corresponds to a latest updated configuration that was available before starting to compute said each computed state. While repeatedly computing a state of the MPS: a surrogate function is obtained, upon completion of each computation, which surrogate function approximates a function of said each computed state; and at least one type of feedback is repeatedly provided via the UIS in respect to said user inputs received. Said at least one type of feedback is provided by sampling the configurations being updated and by evaluating a last surrogate function obtained, and/or a function derived from it, according to the sampled configurations, at a frequency compatible with real-time user-interactivity. The present invention is further directed to related computerized systems and computer program products.
