摘要
An event analyzing device (10) includes an event data collector (101) configured to collect event data which represents an event including an alarm which has occurred in a plurality of devices in a plant and an operation performed to the devices, a process data collector (103) configured to collect process data of the devices in the plant, a trend change detector (104) configured to detect a trend change of the process data collected by the process data collector, an event data converter (105) configured to convert the trend change detected by the trend change detector into a process change event represented in the same format as the event, and a cause-effect relationship analyzer (106) configured to integrate the event data collected by the event data collector and process change event data which represents the trend change in the process change event converted by the event data converter to analyze a cause-effect relationship between the event and the process change event.
