Abstract
An event analyzer includes: an event collector configured to collect event log data representing operation history which an DCS operator performed; a basic unit operation analyzer configured to analyze event log data, and extract basic unit operation data representing operation method based on the operation by the DCS operator; and an unit operation analyzer configured to analyze basic unit operation data, and extract unit operation data representing intention of the operation by the DCS operator.
Claims20
An event analyzer comprising:
- an event collector configured to collect event log data representing an operation history of operations performed by an DCS operator;
- a basic unit operation analyzer configured to analyze the event log data, and to extract basic unit operation data representing an operation method based on the operations performed by the DCS operator;
- and
- an unit operation analyzer configured to analyze basic unit operation data, and to extract unit operation data representing operational intentions of the operations by the DCS operator.
An event analysis method using a computer comprising:
- collecting event log data representing operation history which an DCS operator performed;
- analyzing event log data collected in the step of collecting the event and extracting basic unit operation data representing an operation method operated by the DCS operator;
- and
- analyzing basic unit operation data extracted by the basic unit operation analyzer in the basic unit operation analyzing step and extracting unit operation data representing operation intention of the operation by the DCS operator.
A non-transitory computer readable storage medium that stores a computer program for causing, when executed by a computer, the computer to perform:
- collecting event log data representing operation history which an DCS operator performed;
- analyzing event log data and extracting basic unit operation data representing a operation method operated by the DCS operator;
- and
- analyzing the basic unit operation data and extracting unit operation data representing a operation intention of the operation which the DCS operator performed.
