Abstract

The present paper deals with pairwise comparative analysis of two reliability models with regard to undertaking the failed unit by ordinary or expert repairman in the concept of instruction and replacement time. In model-1 if at the time of completion of the repair of a failed unit by the expert the second unit is found in failed state, it is also repaired by the expert. In model-2 every failed unit first goes under the repair of ordinary repairman who starts repair after getting instruction from the expert.
