The allocation of spare parts for deployed Naval aircraft is delineated by an aviation consolidated allowance list AVCAL. The current policy for stocking AVCALs has been found inadequate to meet the Chief of Naval Operations 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. Author
