Research for RBS

In a previous research, we showed how the Navy can cut the cost of carrier Aviation Consolidated Allowance Lists (AVCALs) by as much as 26 percent without cutting readiness by implementing Readiness-Based Sparing (RBS). The RBS method of selecting inventory allowances is different from the current Demand-Based Sparing (DBS) method in that it links supply resources to aircraft readiness at least cost. Our earlier RBS work prompted the Navy to conduct an at-sea test of an RBS AVCAL on USS AMERICA. The Navy asked us to perform the analysis and report the results. In this memorandum, we analyze how well AMERICA's new RBS AVCAL supported the airwing during its 1993-94 deployment and report our findings. We summarize the results of our analysis and the aviation support lessons we learned. We discuss how RBS AVCALs fit into the Integrated Logistics Support (ILS) system, present our analysis approach, and describe our analysis of mission capable rates, maintenance operations, and cannibalization actions.

This research memorandum presents a means of calculating the expected length of 'awaiting-parts time' of weapon replaceable assemblies, which are needed to calculate aircraft readiness in a multi-indenture, readiness-based sparing model. The method presented is appropriate for any other level of indenture. Although full scale application of the model is not feasible at this time, the model aids in comparing and evaluating existing models.
