This study investigated pipeline spares calculation with four life cycle cost models for the Maverick Missile System. The research goal was to evaluate any differences in the pipeline costs that were calculated by the Hughes Cost of Ownership Model, the Maverick Life Cycle Cost Model, and the Modified METRIC Maverick Model, and a variation of the Modified METRIC Maverick. The analysis was accomplished by identifying the independent variables with a Factor Analysis. A Factorial Design of three factors and five levels was used to develop the observations that were used by the life cycle costs models to calculate pipeline costs. The relative affect that each of the independent variables had upon the pipeline costs was evaluated by an Analysis of Variance. Differences in life cycle cost models pipeline costs were determined by Tukeys procedure. The results indicated that costs produced by the Hughes Cost of Ownership Model and the Modified MOD-METRIC Maverick calculated equal pipeline costs, but the Maverick Life Cycle Cost Model and the MOD-METRIC Maverick did not compute costs equal to any other life cycle cost model. The independent variables of Mean time Between Failure and the Depot Cycle Time had the most effect upon each of the life cycle costs models pipeline costs. Author
