- Abstract
This paper considers an advanced replacement model for a two-unit system. One is the key unit called unit 1 and the whole system is replaced once unit 1 fails. The system is preventively replaced in order to prevent failure of unit 1. The other unit referred to as unit 2, is cheaper and easily replaceable. Unit 2 is only replaced when it fails. However, if its failure is within a threshold of the planned preventive system replacement, the system replacement is done in advance to avoid over replacements of unit 2. A framework is proposed to jointly optimize the preventive replacement interval and the threshold for advanced replacement.
