Stochastic analysis of a reliability model for one-unit system with three types of repair policy

Abstract

The present paper investigates a one-unit system with two types of repairman and resume/repeat repair policies. On the failure of the unit, it is undertaken by an ordinary repairman with the known fact that he may not be able to do some complex repairs. There may also be the possibility of rather damaging the unit by him during repair resulting it to go into more degraded stage. When the ordinary repairman finds himself unable, an expert repairman comes who first discusses the process of repair done by the ordinary repairman and then adopts either resume repair policy or one of the two types of repeat repair policies. System is analysed by making use of regenerative point technique and various measures of system effectiveness are obtained. Profit is also evaluated.
