Abstract
The allocation of spare parts for deployed Naval aircraft
is delineated by an aviation consolidated allowance
list (AVCAL) . The current policy for stocking AVCAL '
s
has been found inadequate to meet the Chief of Naval
Operations 1 (CNO) goal for stockage level effectiveness.
This led to the development of the Retail Inventory Model,
Aviation (RIMAIR) as an alternative stockage policy.
This thesis compares the two models on the basis of
stockage level effectiveness (ratio of demands filled to
total demands) and the availability afforded three hypothetical
systems.
The RIMAIR model allows the budget constraint to dictate
stockage levels while the current policy is deterministic.
However, RIMAIR stockage levels are bounded by
both a minimum and maximum constraint which limit its flexibility.
As a result, RIMAIR stockage levels and total cost
are considerably higher than currently allowed. The
effectiveness and availability measures are also much
higher. A modified RIMAIR model provided increased effectiveness
and availability on an equal cost basis with the
current policy.
