A generalized geometric process based repairable system model with bivariate policy

The maintenance model of simple repairable system is studied. We assume that there are two types of failure, namely type I failure (repairable failure) and type II failure (irrepairable failure). As long as the type I failure occurs, the system will be repaired immediately, which is failure repair (FR). Between the (n-1)th and the nth FR, the system is supposed to be preventively repaired (PR) as ...
