Event analysis apparatus, an event analysis system, an event analysis method, and an event analysis program

摘要

An event analysis device includes an event collector configured to collect event log data which represents operation history of a DCS operator; an event analyzer configured to analyze event log data collected by the event collector to extract analysis result data representing operation method based on the operation of the DCS operator or analysis result data representing operation intention based on the operation of the DCS operator; an operation sequence extractor configured to extract analysis result data respectively in every period in specified multiple periods and extract operation sequence sorting analysis result data based on operation time; and an operation sequence clusterer configured to cluster the operation sequence based on the degree of the similarity between the operation sequences which are different from each other.
