The Influence of Systems Support Division Funding and Safety Levels on Aircraft Availability.
Abstract
The Systems Support Division (SSD) of the Air Force stock fund finances wholesale and retail supply levels for the set of consumable repair parts assigned to the Air Force for management in the DoD supply system. This work describes how fluctuations in SSD funding are likely to affect aircraft availability rates. It shows that at current funding levels, a moderate, one-time reduction in SSD Obligational Authority (OA), if managed through temporary reductions in wholesale order quantities, is not likely to have a significant effect on weapon system readiness. Aircraft readiness is more sensitive to SSD safety levels than to order quantity reductions. Deep or repeated cuts in SSD OA (because such cuts could force safety level reductions) can have more serious effects on aircraft availability. Thus, the small effect of a one-time cut does not mean that SSD budgets can, or should, be cut. In fact, SSD supply performance since 1980 suggests that the Air Force Logistics Command (AFLC) should be increasing SSD safety levels. The report includes source code (FORTRAN) for a PC-based analytic inventory model used to emulate the AFLC SSD requirements system, along with a 320-item 'template' of unit cost and demand data for SSD items, used to calculate and project overall SSD supply performance.
