For many critical machines the only source of diagnostic knowledge is passive experiment during machine operation. If we treat the observed vibration symptoms for a group of machines as an outcome of the Weibull type stochastic process we can calculate the average symptom life-curve and the alarm and break-down ratio. These appear to be dependent on the Weibull shape factor (existing machine quality) and maintenance parameters used at a given plant. The results of passive experiment shown in the paper confirm fully the paper’s theoretical consideration.
