Analysis of South East Asia Maintenance Data to Develop a Method for Predicting Demand for Reparable Items.

Abstract

The War Readiness Spares Kit (WRSK)/Base Level Self-Sufficiency Spare Requirements Computation System (D029) is currently used to compute the demand rates (DRs) and spares levels (SLs) for WRSK line replaceable units (LRUs) from peacetime failures per flying hour. This thesis applied linear regression analysis on C-130 aircraft subsystems data, collected during the South East Asia conflict to calculated LRU DRs. The results indicated the reciprocal for flying hours the number of aircraft, and the reciprocal of average sortie length rather than flying hours were better determinants of the C-130 subsystem DRs. A WRSK was created by apportioning the subsystem DRs to the LRUs under the subsystems. The D029 marginal analysis methodology was applied to refine this WRSK. The final WRSK (WRSKs) a D029 WRSK, and a WRSK with the DRs from WRSKs and the SLs of the D029 WRSK were input into the Dyna-METRIC model to evaluate the effect of each WRSK on aircraft availability for a 30 day conflict without resupply of spares.
