Demand Based Initial Spares Cost Estimating in Early Acquisition Phases.

摘要

This study was performed to determine whether demand based budget estimating techniques for initial spares could be applied during the early acquisition phases of new weapon systems in place of the more traditional cost factors approach. A demand based approach was developed using the AFLC Logistics Support Cost model and compared to the computational techniques used to develop spares buy quantities in both the initial and replenishment provisioning processes. It was found to be sufficiently representative of these processes to justify its use as a budget estimating tool. A test case was performed to determine whether the demand based approach could be applied to a weapon system actually in early acquisition. The test showed the approach was executable, provided a reasonable estimate, and offered several significant advantages over current estimating techniques. This paper describes the study, its results, and the potential uses of the demand based techniques.
