The new fault data base allows a more detailed overview of the faults that are reported. In Table 2 the number of faults and total time lost as a function of the system and kind of fault is presented.
|For each system-type category the total number of faults and total time lost are given|
One thing that one can see from Table 2 is that the relative limited categories both in system and type do provide a proper frame work to classify the large majority of faults. The simplicity of this system makes it also much easier to search the data base and allows us to draw more general conclusions about the problems. A straightforward conclusion from the information in Table 2 is that the main problems we have are with the electronics of the building.
