  • Publication number: 20240020895
    Abstract: A chart generation method includes: extracting history information for sensor data detected from an apparatus that corresponds to the state of the apparatus at the time when a specific event has occurred; generating a chart representing time-series data obtained by statistically processing the extracted sensor data history information with reference to a memory unit that defines a statistical processing technique; and displaying the generated chart on a display unit.

  • Publication number: 20240012373
    Abstract: An information processing apparatus includes an acquisition unit that acquires a physical sensor output value output from a plurality of physical sensors installed in a substrate processing apparatus; a prediction unit that predicts a virtual sensor output value of a virtual sensor corresponding to a prediction target physical sensor by using a statistical model or a physical model, based on a degree of similarity between the physical sensor output value and data learned by the statistical model; an abnormality determination unit that compares the physical sensor output value of the prediction target physical sensor with the virtual sensor output value of the virtual sensor, thereby determining whether an abnormality occurs in the physical sensor; and an instruction unit that switches from a control based on the physical sensor output value to a control based on the virtual sensor output value when determined that the abnormality occurs in the physical sensor.
