Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for determining whether an operational metric representing performance of a target machine has an anomalous value. SOLUTION: The method includes a step of collecting operational data from at least one machine, and a step of calculating at least one exceptional anomaly score from the obtained operational data. Moreover, the method may include a step of aggregating the operational data, a step of creating at least one sensitivity setting concerning exceptional abnormal scores, a step of creating at least one alarm based on the exceptional anomaly score and/or the operational data, and a step of forming at least one heat map. The heat map exhibits the exceptional anomaly score and/or the operational data visually. COPYRIGHT: (C)2009,JPO&INPIT
