Developed drilling states require memory. Choose windows, trends, persistence, event aging, coordinates, and context resets from the physical process and decision timescale.
Read article →When evidence cannot separate plausible causes, unable to determine is the correct result. Explain the missing, conflicting, or out-of-domain evidence.
Read article →A detector identifies a departure; an alert decides whether it is reliable, consequential, timely, and actionable enough to interrupt the right person.
Read article →Event detection decides whether an abnormal condition warrants action; continuous optimization searches for a better admissible operating region. Their designs differ.
Read article →A meaningful change is a contextual departure with sufficient magnitude, persistence, and corroboration. A threshold crossing alone is not enough.
Read article →Separate sensor faults, real process changes, and bad model context by combining physics, supporting channels, operating state, persistence, and explicit uncertainty.
Read article →Time preserves operational sequence; depth preserves location. Converting between them changes eligibility, weighting, aggregation, and resolution.
Read article →Choose sampling rate from the shortest behavior that must remain visible. Acquisition, analysis, aggregation, and display can operate at different rates.
Read article →Rig state gives raw channels operational meaning and routes each interval to the correct KPI, model, event detector, or alert. Classification errors propagate everywhere.
