Claim 44:
45. An information processing method, comprising:
reading a common condition corresponding to a group to which an operating target vacuum pump belongs from a storage apparatus in which the common condition of an occurrence tendency of an abnormality data of a vacuum pump belonging to a setting group determined using an occurrence tendency of a first abnormality data detected from data of a state quantity of the vacuum pump belonging to the setting group of the vacuum pump is stored for each setting group, wherein the setting group of the vacuum pump is a group of a vacuum pump corresponding to an identical manufacturing number, or a group of a vacuum pump connected to a semiconductor manufacturing apparatus corresponding to an identical manufacturing number, a group of a vacuum pump used in an identical process, the common condition is a data indicating a time change in a permissible range of the abnormality detected in the data of the state quantity of the vacuum pump belonging to the setting group:
detecting a second abnormality data from data of a state quantity of an operating target vacuum pump; and
comparing the read common condition with an occurrence tendency of the detected second abnormality data,
wherein in the comparing, comparing the data indicating the time change in the permissible range of the abnormality with a time series data of the abnormality detected from the data of the state quantity of the operating vacuum pump.
