Flying,Maintenance,and the Sale of Parts to the Field. Interactive Models for AH-1and CH-47Systems.

摘要

Computer-generated graphic displays are used to investigate the relationships of AH-1 and CH-47 fleet flying hours, and of maintenance occurences of short and long duration during selected peacetime and wartime (RVN) periods. The rationale for observed relationships is explored in detail, and the discussion is supported with the results of correlation analyses. A similar approach is sued to explore the relationships existing between monthly gross sales of stock-funded airframe parts to the field and the number of short and long duration maintenance events, and between those sales and monthly fleet flying hours. The AH-1 and CH-47 fleets are examined during a peacetime period of 1-1/2 fiscal years. The two elements of the study are shown to be complementary and suitable for the construction of interactive models of operations and supply support. A probable connection is postulated between managed field maintenance support activities and the cost-effectiveness of On Condition Maintenance (OCM) world-wide team visits.
