Operational risk analysis server and operational risk analysis system

摘要

Deep-drilling designating the event generation primary factor which is as frequent appearance augmentation tendency, from combination of the event generation primary factor which the occasion where the event generation primary factor which from the operational risk event which is stored in database 4 is frequent appearance augmentation tendency is selected, the selection target, it is possible, is in frequent appearance augmentation tendency to select according to the relative abundance for other than that event generation primary factor limiting to the combination of the event generation primary factor of specification, with the operation tonnage of the event generation primary factor, furthermore it offers the operational risk analysis server and the operational risk analysis system which can select. As for analysis server 1, appearance frequency risk event number of cases of pattern, from the operation tonnage, or selects the combination pattern of the event generation primary factor of the narabaso which is more than risk event number of cases of the pattern which is abnormally selected at the number of small-numbered entries, significantly below level of significance threshold concerning the combination pattern of the event generation primary factor above the smallest frequency threshold.
