In an effort to improve aircraft availability, this research
compared the efficiency of ten methods of determining
variance-to-mean ratios (VTMRs, VMRs, V/Ms) for repairable, spare
aircraft parts known as reparables. These methods are base pipeline
quantity, Hill-Stevens (220 LRUs), a variation of Hill-Stevens (10
1s), Hill-Stevens (230 LRUs), the Sherbrooke, a variation of
Sherbrooke (10 1s), historical data, a new regression function,
variance-to-mean ratio equals 1.00 or variance-to-mean ratio equals
1.01. Using VTMRs derived from quarterly organizational
intermediate maintenance (OIM) demands for line-replaceable units
(LRUs) from the D200A Secondary Item Requirement System (SIRS)
databases in aircraft sustainability model scenarios and Excel
spreadsheet simulation, this research concluded the VTMRs have an
impact on aircraft availability and the cost of inventory.
