Inventor(s) include Tan, Ruomu; Kotriwala, Arzam Muzaffar; Song, Chen; Hollender, Martin; and Fechner, Tobias.

The application for the patent was published on Nov. 14, under issue no. 46/2025.

According to the abstract released by the Intellectual Property India: "A computer-implemented method (100) for identifying and/or analyzing operating states (2) of an industrial process (1) that is being executed on an industrial plant, comprising the steps of obtaining (110) at least one time series (3a) of measurement values of at least one process variable (3) of the industrial process (1); determining (120), from the at least one time series (3a), using a given classifying logic (4), for at least one point in time in the time series (3a), at least one operating state (2) of the industrial process (1); and from one or more of at least one statistical quantity (2a) computed over multiple operating states (2); at least one sequence (2b) of operating states (2); the duration (2c) for which at least one operating state (2) lasts; and o a combination of at least one operating state (2) and measurement values from the time series (3a) that relate to this operating state (2), determining (130) one or more of at least one quantity of interest (5) that further characterizes the operating state (2) of the industrial process (1) a fitness (6a) of at least one given model (6) for explaining the time series (3a) of measurement values; and o a fitness (3b) of at least one measurement value of the time series (3a) as a training example for the training of at least one machine learning model (1), and/or o training (140) a model (6) that describes the behavior of the industrial process (1) in the operating state (2) determined by the classifying logic (4)."
