Some promising methods for improving predictive techniques used in estimating future demands of aircraft spare parts. As emphasis is on the improvement of demand estimates per program element, the study is based on the transactions of B-52 parts consumption from two bases for a period of 33 months. Only Hi-Valu and Category II parts are considered. It is indicated that about 25 per cent of the sample parts showed zero demand through 21 months of data. Other conclusions are drawn as to preferred techniques for particular parts.
This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
