Patent ID: 8094016

Claim:
A status determination method of determining a status of an apparatus and outputting a result of determination, the status determination method comprising: collecting a plurality of types of status data indicative of current status of the apparatus at a plurality of points in time; calculating a feature value from each of the status data, the feature values corresponding to a change over time in corresponding status data; performing multiple determination operations to output multiple determination results, the multiple determination operations being performed by using any one of determining whether status data corresponding to a single target feature value among the feature values indicates an anomalous status or a normal status by using different discriminant criteria to obtain a determination result, and determining whether status data corresponding to a plurality of target feature values among the feature values indicates an anomalous status or a normal status by using different discriminant criteria to obtain a determination result; majority voting including assigning a weight value to each of the determination results obtained at the performing to obtain weighted determination results, the weight values being determined in advance, performing majority vote to determine which ones of the weighted determination results indicating the anomalous status and the normal status are in majority, and determining whether the apparatus is in an anomalous status or a normal status according to the weighted determination results that is determined to be in majority at the performing majority vote; and displaying the determination results obtained at the performing on a single display area such that the determination results indicating the anomalous status are visually differentiated from the determination results indicating the normal status, wherein the determination results are displayed differently depending on magnitudes of the weight values assigned to the determination results.
