This thesis develops a methodology for updating the Navy's Logistics Factors File, which has been neglected in recent years and requires updating. This study is limited to Repair Parts (Class IX of the Department of Defense Supply Class Codes) for the following four classes of ships: CVN-68 (Nimitz class) Aircraft Carriers, CG-47 (Ticonderoga class) Guided Missile Cruisers, DD- 963 (Spruance class) Destroyers, and FFG-7 (Oliver Hazard Perry class) Guided Missile Frigates. The current Logistics Factors File structure includes a single data entry in pounds per unit per day to describe the sustainment requirements of these units for all of the supply classes and their respective subclasses. For Repair Parts, these values are severely understated when compared to contemporary data. These 'pounds per unit per day' random variables have heavily skewed distributions. These distributions can be fitted with mixtures of standard probability distributions, and it seems wise to recommend that associated variability information be included either directly in the Logistics Factors File, or in a readily available companion source.
