A Time-Replacement Policy for Multistate Systems with Aging Components under Maintenance, from a Component Perspective

Table 1

Failure-rate function of each component between states.

	0.18+0.04 t	0.18+0.04 t	0.28+0.08 t
	0.14+0.02 t	0.14+0.02 t	0.24+0.04 t
	0.12+0.01 t	0.12+0.01 t	0.22+0.02 t

	0.30+0.10 t	0.30+0.10 t	0.40+0.20 t

Note: is the failure rate at time (hrs) of each component from state to state .
