Method and device for identifying correlations between alarm messages or between alarm messages and operator interventions

摘要

The correlations identification method involves analyzing, via market basket analysis method, the historical data relating to alarm messages and operator action that occurred at fixed intervals, as a market basket. A data processing device, which has access to the historical data, forms a quality characteristic from a relationship between respective operator actions before and after the occurrence of a respective alarm message, and from the correlation between alarm messages and operator actions. An independent claim is included for the correlations identification device.
