Reliability of critical component may be traded off
with a replacement policy, assuming that component is detected in time, and the recovery
time is acceptable.
Replacing a component is also costly, and it might involve interruption in the
system functionality.
The costs of reliability should be compared with those
due to the interruption and recovery activities.
