Cost Effectiveness Approach to B-1B Consumable and Reparable Procurement Strategies

摘要

This research utilized a cost effectiveness approach to evaluate the procurement of B-1B bomber spare parts used for base-level maintenance operations. The average number of backorders and average mission capable (MICAP) hours data for 32 Federal Supply Class (FSC) categories were drawn from an Arena simulation model based on historical supply and maintenance data from Ellsworth Air Force Base, along with corresponding cost data from the Air Force Total Ownership Cost database. With this data, the cost per average MICAP hour for each FSC was analyzed to identify which FSCs are most likely to positively influence MICAP hour reductions in a cost effective manner. An analysis of alternative procurement methodologies demonstrated the benefits of utilizing a strategy that targets incremental procurement of spare parts starting with the lowest cost per MICAP hour. This cost per MICAP hour approach provided the greatest benefit as a result of efficiently allocating resources toward FSCs that have the greatest influence on MICAP hours. This approach provides an alternative method to execute funding in a cost effective manner with the added insight into how the execution of funding can improve the stockage of parts most likely to reduce MICAP hours and improve aircraft availability.
