Abstract
Maintenance of technical systems aims at retaining their reliability and availability,
restoring their capability of continuing their operation in case they have failed. A number
of reliability and maintenance policies that play a significant role in reducing system
failures and in making cost-effective decisions on whether to repair or replace a system
will be examined in great detail.
This research report places greater emphasis on the total repair cost (TRC) limit policy
and compares it with other polices like the economic lifetime (EL) policy. The maintenance
cost rate will be used to obtain the optimal parameters.
When a system fails, it is replaced with an identical unused one if the total repair cost
goes beyond a pre-determined repair cost limit by a preventive replacement if in the
time period (0, v) no failure forces a replacement of the system. Else, a repair is carried
out.
