Casestudie Breakdown prediction Contell PILOT - Transumo

This way of visualizing data is the most often way, past time data is looked at
[Weerdesteyn06]. Due to missing additional decision support, this is currently the
only way “data analysis” can be done. In fact, the person in charge has to analyze
the behavior of the different monitored devices by having a look at their graphs. In
case of an uncommon behavior, it is necessary to look at this specific graph more
frequently.
The third way, data can be displayed by the use of XiltriX, is basic statistics. It offers
additional information to determine the current condition of a monitored cooling
device. Although statistical analysis is a powerful method to detect changes in
behavior, the current approach is too simple, as described in the following. 21
Figure 3-6: XiltriX – Available Statistical Information [DEMO06]
Figure 3-6 presents the currently available statistical data. Again, the calculations
refer to the same dataset as above. The single columns contain the channel number
of the connected sensor as well as the minimum, the maximum and the average
temperature value. Furthermore, the standard deviation, the number of occurred
