Assessing Aircraft Spares Support in a Dynamic Environment.
Abstract
Funding to provide for replenishment of reparable spares in the United States Air Force (USAF) is appropriated through Budget Program 1500 (BP-15), the Aircraft Replenishment Spares Program. BP-15 includes the Peacetime Operating Stock (POS) essential to the peacetime readiness goals of the Air Force, as well as the War Reserve Materiel (WRM) needed to sustain forces in a conflict. The requirements for the POS and WRM portions of BP-15 have always been computed separately using analytical techniques that differ widely, making the interrelationship between peacetime readiness and wartime capability hard to understand and quantify accurately. The Logistics Management Institute's (LMI's) Aircraft Availability Model (AAM) has been used since 1972 by Headquarters USAF in assessing the PIS requirement. The AAM is a stochastic, multi-echelon, multi-indenture inventory model that relates the POS portion of BP-15 to a measure of materiel readiness called the 'aircraft availability rate'. Consistent with its use as a long-range planning tool for peacetime, it is dependent upon a body of 'steady-state' inventory theory techniques. This working note describes a recent effort to extend the AAM's capability so that it can assess aircraft availabilities throughout a dynamic conflict scenario.
