A new parameter is introduced for modeling the reliability of systems with standby spares. Dependability, d, is defined as the conditional probability that the checker reports a module as good given that the module is good. The trade-off between the number of spares and dependability then is examined.

The purchasing policy of spare parts for maintenance and the reverse inventory chain logistics has been attracting researcher’s attention in recent years.
