If in the M/G/1 retrial queue with server subject to active breakdowns, the service time distribution [B.sub.1](x) and the repair time distribution [B.sub.2](x) are NBUE (or NWUE), then the stationary distribution of the number of customers in the system is less (respectively, greater) relative to the ordering [[less than or equal to].sub.v] than the stationary distribution of the number of customers in the M/M/1 retrial queue with server subject to active breakdowns and exponential repair time.
If [B.sub.1](x) and [B.sub.2](x) are NBUE, then [B.sub.1](x) [[less than or equal to].sub.v] [B.sup.*.sub.1](x) and [B.sub.2](x) [[less than or equal to].sub.v] [B.sup.*.sub.2](x) (the inequalities are reversed if [B.sub.1](x) and [B.sub.2](x) are NWUE).
Indeed, the simulator can estimate the stationary distributions of such a system when the service and repair time distributions are NBUE or NWUE.
