摘要
Provided are an operational risk analysis server and an operational risk analysis system in which, when an event occurrence factor having a tendency for a more frequent occurrence is extracted from operational risk events stored in a database (4), the event occurrence factor can be extracted according to the magnitude of the factor relative to factors other than this event occurrence factor, without the extraction target being limited to a predetermined combination of event occurrence factors or being dependent on the operation volume of the event occurrence factor; and in which the event occurrence factor having a tendency for a more frequent occurrence can be analyzed and extracted to a greater degree than in a combination of event occurrence factors having a tendency for a more frequent occurrence. An analysis server (1) extracts a combination pattern of event occurrence factors having an occurrence rate at or above a minimum threshold frequency if the number of risk events in the pattern is significantly greater within a significance threshold than the operation volume or the number of risk events in a pattern that has been abnormally extracted with a small number of items.
