Claim 43:
44. An information processing system, comprising:
one or more processors configured to detect a first abnormality data from data of a state quantity of a vacuum pump;
the one or more processors configured to determine a common condition of an occurrence tendency of an abnormality data of the vacuum pump belonging to the setting group for each setting group using an occurrence tendency of the first abnormality data detected from the data of the state quantity of the vacuum pump belonging to the setting group of the vacuum pump, 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:
the one or more processors configured to detect a second abnormality data from data of a state quantity of an operating target vacuum pump; and
the one or more processors configured to compare a common condition corresponding to a group belonging to an operating target vacuum pump with an occurrence tendency of the detected second abnormality data;
wherein the one or more processors compare 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.
