The results for mean time to failure, mean time to repair, and
long-term availability for each part are shown in Table2. According to Table2, the sensors have the lowest long-term availability
(0.9846). This is due to a lower MTTF ,since this part is subject to
corrective maintenance on an average of every 11.3 days. The
upper rotating union has the second lowest long-term availability
rate(0.9870).This is due to a higher MTTR, which is around 16h.
Thus, it is observed that actions are necessary to reduce the
number of occurrences of failures in the sensors and to improve
the maintenance routine for the upper rotating union.Since the
production line is a series system,these actions would have a
direct impact online availability..
