* Probability of NO failure in any one
year = .988846691
* Probability of failure in any one year
= .011153309
* The odds of failure in any one year =
1 to 89.65948819.
Note that not until "Y+" the time
elapsed does the population exceed a 50
percent probability of failure. Therefore,
the cost model is as follows:
C = Time value of money LESS the unit
cost of the part
C = $5,046,530 (Weighted cost to stock
the part)
Contribution of areas where the part is
to be spared: $1,776 per hr
Lead time = 7 days
Downtime cost = $298,368.
Should the part be stocked? NO
CONCLUSION
Because the new asset reliability programs
are based on RCM principles, they identify
failure modes. These failure modes, formally
documented, made it possible to apply one of
two major categories of maintenance strategies to the asset:

1. Condition-Based Maintenance (CBM)
maintenance strategy:
* for assets such as bearings which fail
randomly but are eligible for a proactive
inspection task for the detection of
given failure modes (resulting in an
understanding of the state of the given
failure mode at the point in time of the
inspection).
2. A No-Scheduled Maintenance
(NSM) strategy:
* for assets such as electronic devices,
which fail randomly with little or
no notice.
These maintenance strategies require a
different approach for making storeroom
spares decisions (stock vs non-stock), but
taking them into account and with rigorous application of this approach, the mill
achieved a storeroom inventory level of less
than 2 percent of the asset value with an
increase in overall mill uptime.
